DIY CVT repair 01j

In detail: do-it-yourself repair of the 01j variator from a real master for the site my.housecope.com.

At the beginning of the 2000s, Audi was actively developing a continuously variable variator, which was supposed to become an alternative to traditional automatic transmissions. CVT 01J CVT appeared in the proposal of the Audi company in 2002. This CVT was offered for all-wheel drive modifications of A4, A6, A8 cars. The maximum engine capacity was 3 liters. That is why this gearbox was not installed on top-end modifications with powerful power units.

These CVT models were one of the first series-produced transmissions to be installed on Audi vehicles. Note that this gearbox has proven itself from the best side and is capable of running more than 200,000 kilometers without overhaul. Due to its design features, the automatic variator 01J CVT it has a compact size, which makes it easy to install it on small-sized Audi A4 models.

Weak point automatic transmission 01j is the control unit. This element does not have the proper resistance to temperature extremes and can fail in summer heat and in subzero temperatures. We also note the fact that regular oil change using high-quality spare parts is the key to trouble-free operation of the variator. To carry out a complete oil change, you will need 7.5 liters of original gear oil. In some cases, there may be problems with the tightness of oil seals and gaskets. All this leads to loss of oil and insufficient pressure in the system. This variator is extremely critical to the quality of the lubricant mixture and the oil pressure in the system. At the first signs of a breakdown, messages appear on the center panel of the vehicle. When such a message appears, the car owner should contact the service center as soon as possible, where they will carry out the necessary repair work.

A common failure is a problem with the clutches, which must be replaced if damaged. The problem is that clutches are sold exclusively as a set and they need to be completely replaced, which somewhat increases the cost of repairs.

Secondary through a reducer.
Primary so. If the secondary is diluted, then the circuit in the primary will come out indiscriminately.
It seems that I have not confused anything.
What are your goals?

Your question is not clear to me.
When they tear a badly going box, then they leave. It is always necessary to disassemble and look, she does not forgive dumb experiments.

AGGREGATKA is a federal network of technical centers, the main specialization of which is the repair and maintenance of automatic transmissions of all types, including robotic transmissions with double clutch, CVT transmissions and classic hydromechanical automatic transmissions

Dear forum users, we really need help, there should be specialists among you who repair or refurbish the jf011e 4WD variator. The problem is when disassembling the valve body, metal balls fell out of it, I don’t know where to put them now. I really need your help. And tell me the addresses in St. Petersburg where at the stand they can check the valve body for me. I thank everyone who will respond to help. Photo of the plate in the attachment

I want to replace the claw, it is also the position sensor of the leading cone))
Protruding parts do not interfere, presumably, the cover guide does not allow you to remove, is it possible?
how much can you pry on and jam the flange? or will the sealant close everything?

update: Removed. Sits very tightly on the guide pins, in my case - on one.
What is the best way to clean the inside? just wipe it with a lint-free cloth? attacked while shooting some trash.

Well, the expected question is how to collect? ))
Apply sealant to the flange according to the instructions, align the triangles on both shafts with temporary longer screws, insert the parking pin into the “very middle” and put my “foot”. Tighten with what moment?

Novel!
You are a sadomasochist

- kroilovo leads to a hitalov.
I would have removed the checkpoint and did it on the removed one.
Here and here look at the pictures on the repair reports

Thanks for the compliment ))
I started this because there is no money, there is nowhere to take it.
I read a lot of forums, I realized that I can.
I do it on the street in the yard under the trees))

Hard. On the street and without a hole
Military field conditions

The last time I did this was in the 90s - I also threw off the checkpoint without a pit

PS I invited the Partner to the topic, we are waiting for his answer, maybe they will tell you what

I didn’t throw off the box, it’s too much for me, I just took off the lid.
I will collect on the weekend, while there is no time.
if you have any advice - I will only be glad.

Wait - so judging by the photo, the cover on the drive side?
and according to other photos you have already opened the box.
What happened to the plug? How did you determine what exactly it needs to be changed?

Here in the photo you can see that in the main body there are some guides or rods from forks or something else

Interesting description.
Alexey from the partners is not yet in touch. We are waiting for his opinion and advice.
Yes, another question - is the car front-wheel drive or all-wheel drive?

UkRA, before your intervention in the box, this error was not?
Maybe when we drove at a low oil level, the bagel was out of order. Hence, by the way, overheating can easily be.
After removing the error, how quickly does it appear and under what circumstances?

Before the disassembly, this error did not exist, it was only 1778.
Perhaps I assembled the valve body in the wrong way, I disassembled it, washed it, I could confuse the springs or the solenoids could not be pushed into the landing gear - anything happens for the first time))
Now I have drained the oil, it’s gray - is it sharpening my foot again? Remained in a bagel liter 2, could they paint the remaining 7? or something different?
The error pops up when the box warms up and tries to block the GT. I erase it and almost immediately again. Although it was that the error was gone - it means I could))
I attach a file with the parameters of the last trip, look at line 3358: TGT_SEC_PRESS suddenly scales.

He removed the valve body - relapse.
Apparently, the low oil level was not so low - the reason is different, what? Help.

It seems that I have found the reason 744 - the TCC valve does not fit tightly into the connector.
Now to understand the reason for sewing the paws, where to dig?
Help! Help !!

Club partners also can not give advice? then it probably makes no sense to go to them for repairs - they will look for a malfunction for your money.

You, Qashqai, have a bunch of topics on the paw (like a sore?).It all comes down to a malfunction of the dptchikstep motor (this is by reading the topics).
Youtube Video

Roma!
1. Have you been with partners in the service? You are doing military field repairs.

2. Can you diagnose remotely? Me not. I think partners too.
For it is necessary to see live, and not from photos and videos. From the photo video, we can only guess and guess.
Again, with such wear it should give errors. Do you have them? Give me the numbers. We will give you instructions on where to dig. Again - the instructions of the MMS-PSA, not Nissan.
3. You came to visit with a non-core car and you run into

And what about in kashkai clubs? Can't anyone tell? It turns out yes, since you came to us for help.
4. Do you think that everyone is on the online forum around the clock? Have you tried to call Partners?

NL, but sometimes it's better to chew.

I do not want to argue with you, because as a guest here, thank you for sheltering))
I am asking and looking for help in many places, but so far I have not been able to find the cause of my illness, everyone gives the same links to different reasons.
I "stuck" to you because you have a specialized partner in boxes.
For example: how can slip bearings affect the fork if the cone gets its rotation relative to the cover anyway? It comes to the point that the bearing almost grinds the balls into porridge, but the fork is in order, and I have no noise, but the fork was cut?
It seems to me that the more actively the partner helps in the topic, and for this he becomes a partner), the people reading understand that the partner is really competent, and not like that, you come, we will throw off the karobasik, split it, take out everything, wash it, replace what is there not so, we collect, we will fill in fresh butter and you will go as on a new one - 50-100tr.
Tell the astronauts or anyone else in distress about remote assistance - that's exactly how I do it now and I don't want you to find yourself in such a situation, no matter how you stutter from it.

And when will they repair cars if they hang out on the forum all the time?

Yes. When troubles, they have video communication and a full set of diagrams / drawings / manuals / instructions and a staff.
Everything seems to be on a voluntary initiative with us. And I have so generally a hobby

I repeat - call the Partner and talk.

PS NL, but when I encountered problems, I called and / or went to the service / specialists of the Club and decided everything there, and not in the parking lot on my knees through the forum, waiting - when they would answer me.

You talked about the army there, why didn't you call the service or you would go or call a technician, or then you had different conditions and other times. I'm not busy, should I continue

upd:
Let me rephrase everything I wanted to say again:
Baloo! You are welcome! Could you once again disturb the guys-partners on my question, I really need their help!
Thank you in advance, guys-partners and all who responded !!

UkRA, inspect carefully the surface on the cone on which the “foot” works. There are no scoring, scratches, etc. on it.
I still didn't get it. may not have read it carefully. Have you examined the cone bearing seats?
For good reason, the variator must be removed and disassembled. I do not insist that you give a lot of money to the service, you can do it yourself. Your hands grow from the right place, your head understands, judging by your thoughts. Therefore, when you spread the variator on the table and under normal conditions, you will most likely see the problem yourself, if not, then 89030013099 Alexey.

The "scattered" variator is on the car! A bad diagnosis is made by partners over the phone. Well this is a carburetor on a six.

I opened my varik, all 3 seats under the bearings of the cones are already blue from slipping 40-50% of the surface, however, the step foot is like new .. I think once the foot is erased, it means it wedges somewhere .. maybe the valve itself wedges the one that is on the primary pressure of the cone (try stick it on a break) if it wedges, then 100% in it is the case

Variable speed drive 01J (CVT 0AN Multitronic or VL-300) released by Audi in collaboration with LuK GmbH & Co in 2002 for the popular all-wheel drive models A4, A6 and A8. With engines from 1.8 to 3 liters. Transmits up to 310 Nm of torque.

Refurbished Multitronic VL-300 on ZF variator 01J.

Two variants of Multitronic are known to be repaired:

- Square connector (on right 130446 B).

- With K round connector (left 130446A).

Although the investment in a proprietary European CVT project was astronomical, this pull-belt CVT design could not compete with DSG and push-belt CVTs. Many designers and financiers consider such a design to be a dead-end branch of automatic transmission development and an unsuccessful investment by Audi.

CVTs are gaining more and more popularity among the varieties of gearboxes. So the carmaker Audi did not stand aside and installed variator gearboxes on the new A6 C6 models.

Each of the above listed elements can fail at any time. In today's article, we will analyze with you the main malfunctions of the Audi A6 variator, their causes of failure and methods of self-repair.

Earlier I already told you about how to replace the fuel filter Audi A6 with your own hands, so anyone interested can read this article by clicking on the link.

Most of the malfunctions in a CVT gearbox arise from improper operation, which I would refer to:

Violation of the frequency of replacement of the working fluid
Violation of the frequency of filter replacement
Using poor quality fluid
Aggressive driving style

In addition, there are other malfunctions that are determined using computer diagnostics. Each malfunction has its own diagnostic code. The codes determine:

malfunctions of input sensors (working fluid temperature sensor, speed sensors of the driving and driven pulleys, pressure sensors in the main line, pressure in the driving and driven pulleys);
malfunctions of the electronic control unit;
malfunctions of actuators (stepper motor, solenoid valves of pressure in the main line and pressure in the driven pulley, lock-up valves of the torque converter and control of the planetary gearbox).

The most common cause of variator malfunction begins with wear on the bearings of the cones, while a characteristic hum becomes audible. Bearing noise occurs due to the ingress of wear products on their working surfaces, as a result of which they become unusable. Special oil filters retain metal suspension for the time being.

The next reason that can cause problems with the variator is jerking and jerking of the vehicle, which occurs due to the seizure of the oil pump pressure relief valve. The same harmful wear products interfere with the normal operation of this unit, disrupting the stable pressure in the system.

Timely contacting a specialized workshop will help to avoid higher repair costs. Minor damage to tapered pulleys is removed by grinding, while the belt will most likely have to be replaced.

The rather rare malfunctions that precede the breakdown of the variator include the failure of the torque converter, as well as failures in the electronics caused by breakdowns of some elements of the control unit. However, this kind of malfunction occurs quite rarely and is not a regularity, but rather a factor of bad luck.

As I already noticed earlier, the most common variator failure is considered to be worn out bearings for cones. A sign of this problem is a prolonged hum, which manifests itself already when driving 50 thousand km. To change all bearings and their parts, the motorist will have to pay over 34,000 rubles. Such a malfunction most often occurs in Audi A6 C5 cars.

Loud noise of bearings, and then their slow destruction occur for the following reasons. First, the destruction of the working surfaces is facilitated by the ingress of various foreign metal bodies, such as wear products, on them.

The installed oil filter and magnet collecting metal powder cannot block access to the working surfaces of the variator for heavy foreign bodies. In this case, the bearing life will extend the reduction of the engine oil change time to 25 thousand km.

But that doesn't always help. There are cases when some CVTs work quietly for 100 thousand km, while others, under the same operating conditions, buzz even when driving 50 thousand km. High bearing noise is often caused by poor quality bearings, low accuracy and low load ratings.

When it comes to shortening oil change intervals, not all manufacturers share the same point of view. For example. During the warranty period (100 thousand km), Renault advises only to carry out periodic checks of the oil level and condition. At the Audi concern, the oil change must be done once every 75 thousand km.

In addition to the usual machine oil, it makes sense to fill the variators with special oils marked “CVT”, original NS-2 or ELFMATIC CVT fluids. For Audi cars, DiaQueen type CVT-J1 can be used. It is not recommended to pour the oil used in the hydromechanical automatic into the variator, although some little-known manufacturers have adapted their variators for these substances.

Often, when the vehicle is moving, jerks and twitching appear.Reason - the pressure relief valve in the oil pump does not work.

Wear products falling on the contact surface wedge it in an intermediate state. As a result, the pressure level deviates from the norm, which impedes the operation of both pulleys and causes the belt to slip. In this situation, you need to make a visit to the service center as soon as possible.

With timely treatment, repair work will be cheaper: small defects in tapered surfaces are eliminated by grinding.

During diagnostics, specialists often consider problems with the front wheel bearings to be the cause of the noise of the variators, which are immediately replaced with new ones. Replacing these bearings can be costly, since on some machines it is one piece together with the hub, which costs between $ 300 and $ 400.

Many motorists who pull out a stalled vehicle by jogging by quickly moving the lever from position D to R and vice versa, are faced with the following situation - jerks when moving the lever from the parking position to R and D. with friction wheel. The wear of the splines is explained by the absence of a pause when moving from D to R and vice versa (you need to wait for the vehicle to stop). As a result, the gears of the planetary gear must be replaced.

Some drivers, when this problem occurs, immediately begin to check the valve body for malfunctions, which is actually reliable and problems with it rarely happen.

A lot of attention in a stepless unit is paid to the temperature regime. Often, problems in the operation of variators arise from an increase in temperature. In modern cars, a self-diagnosis device is provided, which includes special sensors. When the temperature value rises, they turn on the indicator on the dashboard indicating a malfunction, and the variator is put into emergency stop mode.

To maintain the normal temperature of oils in modern cars, in addition to a heat exchanger, another radiator is installed in the engine compartment near the climate system. Various dirt gets into the bumper through the air duct.

The first sign of a dirty radiator is overheating when the vehicle is moving at high speed. Therefore, once every 3 years (or more often) it is necessary to thoroughly flush the radiator. It would also be nice to install a special mesh in the air duct to protect the radiator from various objects flying out from under the wheels of the car in front.

Despite the mistrust of domestic motorists towards CVTs, Western motorists install this type of transmission with a greater degree of optimism. According to statistics, they break down much less often compared to hydromechanical gearboxes. That is why many car manufacturers, who initially doubted the durability of CVTs, are now being installed more and more every year.

For example, the manufacturer Audi installs variators on a new generation of crossovers with a two-liter engine. Subaru has CVTs for XV, Forester cars. By the way, most of the users of these cars cannot be classified as calm motorists.

These machines are used for high speed cross-country travel. But before, many thought that the variators in such conditions would immediately fail. This means they have become better quality.

A variator is a gearbox without steps (i.e. without the usual gear shifting by means of gear engagement). In fact, there is no gear shifting in the variator at all, the torque is transmitted and changed smoothly, without jerks, and it is limited by the specified parameters.Therefore, a car with such a box is suitable for those who drive without sudden accelerations and stops and want to save a lot on fuel. Instead of the usual gear pairs, this type of transmission has two pulleys connected together by a belt or chain. CVT repair will be associated with them, or with its electronic control.

The variator is quite reliable and rarely needs repair, but there are things that it does not like. This is a fast driving style, constant use of the maximum power of the gearbox and hard braking. The second destructive moment is the working fluid, if it is of poor quality or does not change to a new one according to the regulations. All of the above, individually and in combination, leads to overheating and increased wear of parts and leads to a malfunction of the variator. Separately, it is worth noting the filter element. You should know that every time you change the fluid in the variator, the filter must be replaced with a new one.

Symptoms of a malfunctioning variator in an electrician will be seen immediately. A light on the instrument panel will tell you about this. "Service required"... You can find out in more detail what kind of malfunction is taking place using the variator diagnostics.

The most common malfunction is jerking when driving, as they say "the variator jerks."

These may be malfunctions of the variator control unit, electronic actuators and various sensors, which are abundant in this type of transmission.
Signs of a variator breakdown in its mechanical part are shocks when shifting gears, the inability to manually switch, the gearbox speed does not change, its movement in neutral gear, slippage, or no movement at all.

If you need to get to a car service, then remember that if it is impossible to change speeds, towing a vehicle is impossible in other ways, except on a tow truck. It is also not recommended to tow on a flexible or rigid hitch in the event of other malfunctions, but there is such a possibility if a certain sequence of gear changes is observed, without sudden movements, very slowly and not far.

To repair the variator with your own hands, you will need a lot of knowledge and skills. Not every service takes care of these boxes. The main reason for this is the large number of electrical devices. To check the variator properly, you need to have a whole arsenal of diagnostic equipment, which, by the way, will also see mechanical breakdowns. But if you still decide to fix the problem yourself, then this is possible.

How to identify a malfunction of the variator?

For diagnostics, it is necessary to dismantle the variator and disassemble, before that, carefully disconnecting all the wiring and remembering the sequence of actions. Just like with any other box, this is the only way to determine exactly what is out of order and fix it. Without disassembling the boxes, it is impossible to say unequivocally what kind of problem is taking place. In this case, the cost of repairing the variator will be much cheaper and consist only of purchasing the necessary spare parts.

CVT repair in service

This begs the question - how much does it cost to repair a variator in a car service?

It is quite expensive to repair a CVT transmission, so many car owners prefer buying contract or new boxes to repair.

It is impossible to answer it unequivocally. First, it depends on the make of the car (and the price difference is huge). Secondly, from the type of breakdown. In the best case, it will be flushing the valve body valves with an oil change - approximately 6-8 thousand rubles, replacing these valves - 10-13, replacing the entire valve body - 20-25, complete restoration of all elements - 40-45 thousand rubles (Such calculations are applicable to models Peugeot, Honda). Consider also the price of diagnostic services. Thirdly, the cost of repairing the variator depends on the region in which you live.

This is the selection of the optimal speed range for the engine speed. As already mentioned at the beginning, the variator does not have a gear change in our usual understanding, it moves smoothly within the given framework.

Calibration is setting the desired speed range.

The variator is calibrated either in the process of movement or in the parking lot. Before and after the repair of the variator gearbox, calibration must be carried out.
