DIY opel astra h ecu repair

In detail: do-it-yourself repair of an opel astra h ecu from a real master for the site my.housecope.com.

OPEL Astra, Corsa, Vectra and a number of others with ceramic engine control units installed. The most common failure of ceramic blocks is the appearance of sporadic or non-erasable errors on various sensors. The reason for this is the not very good location of the block in the engine compartment on the engine. The unit is constantly exposed to vibrations transmitted from the engine.

Reports on the repair and restoration of ECUs ("brains") of Opel cars:

Malfunctions of the electronic engine control unit on OPEL vehicles. One of the malfunctions is associated with problems in the operation of the accelerator of the gas pedal. At the same time, the car does not respond to the gas pedal, or the reaction is slow and the car is in emergency mode. Does not accelerate, loss of power, “Check Engine” lamp comes on. Computer diagnostics on one of the cars Opel Vectra B 1.8L Z18XE 2001 showed the following errors:

P0120 - Throttle sensor / pedal position A - malfunction.
P1525 - Throttle valve actuator - malfunction.
P1550 - Throttle actuator motor - System or component in alarm condition.
P0683 - Preheating relay control. Malfunctioning spark plug.
P0603 - ECU. Memory device error or electrical failure.

The cause of this malfunction is in the “brains” of the motor control. We restore ECUs with such faults with a guarantee!

In addition, it is possible ignition malfunctions - these are misfires, the absence of a spark in one or more cylinders. It is also possible to eliminate such irregularities. Typical errors:

P0300 - Ignition misfires detected.
P0301 - Cylinder 1. Ignition misfires detected.
P0302 - Cylinder 2. Ignition misfires detected.
P0303 - Cylinder 3. Ignition misfires detected.
P0304 - Cylinder 4. Ignition misfires detected.

Summing up, I would like to say that Opel cars, on which "brains" are installed, made using hybrid technology, the failure of any sensor or executive component is possible after 8-10 years of operation.

Malfunction of the electronic control unit for the high-pressure fuel pump of the injection pump on OPEL vehicles with a diesel engine. A typical manifestation of a malfunction of OPEL cars with Isuzu injection pump ECU is that the car starts, runs and stalls after a few minutes. Difficulty starting the engine. Over time, the car stops starting. No signal to control the injection pump valve. Computer diagnostics show error 0251.

The owner of the car contacted us with such a typical malfunction. Checks at one of the service stations in our city revealed that the problem is in the injection pump control unit. Soon, the ECU was brought to our craftsmen. After a visual check of the injection pump ECU, a poor soldering contact of the throttle output in the 130V voltage circuit was found. Within a couple of hours, the block was cured, the place of cold soldering was cleaned and soldered. This fairly simple unit malfunction saved the owner several thousand rubles and time. As a rule, it takes more time to find more complex causes of a malfunction.

Malfunction of OPEL vehicles with injection pump ECU PSG5, VP30, VP44 is accompanied by the inability to start the engine. Computer diagnostics show errors associated with the pump control circuit.

In the life of every car owner, especially if he is the owner of an inexpensive and old foreign car, there comes a moment when on the dashboard of the car the icon lights up Check - check the car engine.

One of the reasons for this malfunction on Opel Astra G and H cars is the failure of the ECU (electronic control unit for the car). It is about the brain of Astra that will be discussed in our today's article.

Opel Astra ECU G and H- what models are installed

The petrol engine Z 18 XER DOHC-I is equipped with an electronic engine management system Simtec 75.1 EMS manufactured by Siemens VDO.

Opel Astra ECU repair - wire soldering

The Opel Astra ECU provides camshaft position adjustment and engine temperature control. To perform these functions, the computing power has been increased and additional sensors have been installed.

The design of the control unit located on the intake module has been improved. A new crankshaft sensor and two camshaft control valves for the intake and exhaust valves are used. In addition, a new throttle body is installed with heating from the coolant circuit. Electronic engine control module Simtec 75.1 located on the intake manifold housing and secured by four threaded bushings.

Technical features of the Opel Astra ECU G and H - table

The engine management system has the following differences from the Z 18 XE and Z 16 XEP engine systems:

installed PCB - printed circuit board;
a second camshaft sensor is installed;
a second temperature sensor is installed.

Now I would like to touch on the topic of common malfunctions found on the Opel Astra G and H ECUs

Common malfunctions of the Opel Astra ECU arise for the following reasons:

mechanical damage. The engine control unit is damaged from shock and strong vibrations, which contribute to the appearance of microcracks in its circuits and housing;
sharp jumps in temperature, as a result of which the engine control unit itself overheats;
corrosion;
depressurization and ingress of moisture into the ECU case;
interference in the work of a block of people who do not have the necessary skills;
the so-called "lighting" from a car with a running engine;
rearrangement of terminals when connecting the battery;
starting the starter without a connected power bus.

This is what the Opel Astra G ECU chip looks like

All of the above factors affect the efficiency of the engine control unit in different ways. Some of them cause minor harm to the “brains” of the car, while others can instantly break the block. Fortunately, there is still a way to prevent the final breakdown of the unit - ECU diagnostics, which should be performed at least once a year.... This is the only way to save on expensive part repair or complete replacement.

In most cases, self-repair of the Opel Astra ECU is impossible, therefore, now I will give you step-by-step instructions for parsing and removing.

CHIP48.COM - chip tuning in Lipetsk ›Blog› Repair of ME7.6.2 ECUs in Lipetsk, we repair and bind ECUs to Opel Astra H in Lipetsk!

Over the past two weeks, with absolutely the same breakdowns, they came to me - or rather, they brought two Opel Astra H with 1.4L - Z14XEP engines on a "Tie".

Both cars have the same malfunction - they will not start, and the reason for this is a faulty Bosch ME7.6.2 ECU
The owners and myself made several mistakes while working with the ME7.6.2 ECU.
It turned out to be a pretty penny for the guys. On disassembly on the ME7.6.2 ECU - constant demand, despite the fact that the blocks are old and ancient - the average price for it is 10,000 rubles

Now let's talk about the peculiarities of working with brains on these machines and why are owners trying to save money - overpaying 2 or 3 times more?
1) ME7.6.1 and ME7.6.2 control units were installed on the Astra H in conjunction with the Z14XEP motor - the units are not interchangeable! I am not a strong specialist in Opel, but we were unable to bind ME7.6.1 instead of ME7.6.2
"Strong" Specialists could not answer my questions about the interchangeability of ME7.6.1 and ME7.6.2
People buy these blocks but cannot tie them ...
2) There are two types of ME7.6.2 control units - for Opel Astra H and for Opel Corsa D.
Control unit ME7.6.2 from Opel Corsa, we could not bind to Opel Astra H
Inexperienced people buy and can not do anything with them, taking out the brain for themselves and inexperienced service men
3) 80% of disassembly control units do not have “CarPas” for linking the ECU to another car. ECU without KarPas - not worth a penny ...
Many blocks do not allow getting data from them, "workarounds" also do not give success when working with these blocks - do not buy an ECU if the seller does not have KarPas from ME7.6.2
4) 70% of control units that are sold at disassembly or Avito are either no longer working, or their resource is close to becoming non-working.

ME7.6.2 - made on "Ceramics" - the solution is not so successful ... There is no method by which you can assess the state of the ME7.6.2 control unit
5) Do not try to “tie” the ME7.6.2 ECU to the car yourself. Cheap Chinese devices - make it appear that they are working. Spend time, nerves and money - a lot of money.
To "bind" these particular brains - you need access from the original device to the "Portal" Opel
In Lipetsk, Pavel Zhinkin has such an opportunity - id21909779 (Pavel Zhinkin) - my friend and a professional in his field.

And once again I will repeat two important points -
1) The ME7.6.2 control unit must either already be “Untied” or there must be KarPas to it.
Do not buy an ECU without KarPas, - the price for such a control unit is "0"
2) Do not confuse ME7.6.1 and ME7.6.2 - the blocks are not interchangeable!

Good day!
Opel astra g 2004 Z14XE

Now I scratch my head and think what to do next, the new ECU is definitely not (the price tag is 60,000 rubles). but I've been waiting for 1.5 months.

To everyone who has read to the end, thanks for your patience, I hope that it will be useful to someone.

Thank you

No thanks

tmeter, I didn’t try to call Vadim Sorokin. I don’t have contacts for communication (but I have met somewhere here I think this is not a problem) and I don’t know how it works. To begin with, I thought to write off in order to provide as much information as possible about my ECU (photo number or something else) so that a person's brain does not soar in vain. And the fact that “a proven person does with a guarantee” is what I already understood from the forum, and the auto electrician Andrei is probably familiar with him, he also advised him.

tmeter, Thank you for your help!

I will put in my 5 kopecks, as I was worn out in my time with these blocks.
About the gel.
There are two ways. I tried only one myself.
1. I use YaXun oil-base wash. Dissolves gel well. Then it is simply washed off with alcohol. No sticks. Contacts are not mechanically affected. The board is clean.
2. Before Chinese chemistry came to our market, people used a polyurethane foam remover. I will not vouch - I have not tried it.
Before that, I had tried everything: alcohol, acetone, gasoline, kerasin, nitro solvents, hydrochloric and sulfuric acid (alas, there was no nitrogen), aqua regia, a temperature of 480 grams. Uselessly.

About soldering. I solder the contacts on the comb with the usual POS-61 with aluminum flux (with thorough rinsing). On ceramics it is possible with flux on aluminum, it is possible with ordinary rosin and so and so it takes (of course, with washing).

It was once on the block from the X18XE-1 that two contacts from the flash drive to the ceramic (thinner than a hair) came off.Nothing, soldered - a microscope and a soldering iron with a very thin attachment + a tripod.

But, IMHO, all the same, all such shares do not go for a long time.

BlackRaven, shamanroman, thank you guys for responding!)) Very useful information that is very difficult to find.
To summarize: How to solder and with the help of what (solders and fluxes) the information was received and everything is clear! If, of course, someone can advise some kind of miracle flux, this will not be superfluous!

The experts also explained what conductors to use!
Now we even know how to dissolve this terrible and terrible gel. Thanks BlackRaven
The question of the option to solder the conductors to "blocking capacitors" remains unanswered. The fact is that there are more conductors than conductors, and if it is not possible to solder a conductor to a ceramic pad and the conductor is not called - what to do.

If someone has experience in this matter or schemes, even sketched by themselves, photographs, please share your hard-to-reach experience!

Hello everyone. My ECU Repair Story:
Astra Sedan 1,8 XER automatic transmission
In the spring, the arrows of the speedometer and tachometer began to jump from time to time, the battery charging lamp began to light up, the machine began to dull, switch with delays, the auto-neutral stopped working, the condo was periodically cut down, a couple of times the EGUR stopped working when the car was started. Periodically, the car did not start, the relay in the trunk worked, and the starter did not turn. When pedaling, there were 20 different errors that were not related to each other.

When visiting Autoimport on Kolomenskaya, the masters removed the errors and, without explaining anything, recommended driving - like it's Opel .. well, there are glitches .. As a result, 1400 rubles. for diagnostics, without solving the problem.
In Genser in Zhulebino, the problem was found - a failure of the engine control unit. Discount price 29,500 rubles. waiting for a block from 10 days to a month.

Because the money is not small, we decided to dig into the block, since there is a person familiar with electronics and who knew how to solder this kind of board. The evening was spent on disassembling the “non-separable” ECU block. In principle, they were dismantling in vain, because in the end, as it turned out, the problem is that contacts on 2 connectors, which are fixed on top of the block, began to move away from the vibrations of the block (standing on the intake manifold). Those. it would be enough to simply "squeeze" the pins inside the block. As a result, the block was disassembled, the contacts on both connectors pressed a little into the board and soldered them from the back side. The engine started up at random, but by the evening it began to run, as it turned out, during disassembly, one of the resistors (2nd cylinder) that was on the key was broken. There are a lot of parts on the edges of the board, so when removing the block cover, you need to be careful not to break anything.
As a result, the resistor was changed, the car with the key went out, the engine works as before, there were no problems with the box or with the electronics.

Immobilizer (Immo) Car Pass

The modern engine control system (ECM) is very complex.Developers apply new ideas towards increasing engine power, while reducing harmful emissions of СО СН and increasing its resource. Engineers are introducing a large number of sensors, electronic ECUs (brains) and actuators with kilometers of wires into the creation of modern engine control systems.

The use of a modern electronic engine control system (ECM) allows you to optimize the engine performance to the maximum. It becomes possible to take into account the state of the environment, the quality of the fuel, the degree of engine wear, the driver's control actions on the accelerator and brake pedal, gear shifting - easytronic (isitronic), the operation of electrical consumers, etc.

Electronic control of fuel injection and ignition ensures optimum air-fuel ratio, torque and spark energy.

control of injectors;
control of executive devices (air conditioning, El-thermostat, El-shock absorbers, etc.);
energy and spark management;
control of the electric fan of the cooling system;
crankshaft speed control;
control of the "CHECK ENGINE" warning lamp, check the internal combustion engine, generation of diagnostic trouble codes and interaction with diagnostic equipment;
electronic throttle and gas pedal control;
fuel pump control;
interaction with the immobilizer (anti-fire system);
control of valve timing systems;
generation of signals for electronic units (signals about speed, engine speed, fuel consumption, etc.).
control of the canister purge (EVAP) and exhaust gas recirculation (EGR) valve;

All of the above is carried out according to the results of processing information about the monitored parameters coming from the sensors.

You will need: TORX T30 and TORX E8 keys.
1. Disconnect the wire from the negative terminal of the storage battery.

2. Press down on the latch on the wiring harness holder ...

3 ... .fold the holder upwards ...

4 .... and disconnect the connector from the ECM.

5. Disconnect the second block from the block in the same way.

6. Remove the bolt securing the lug of the "ground" wire to the base of the electronic engine control unit and disconnect the wire.

7. Remove the four bolts securing the ECM to the bracket on the intake manifold ...

9. Install the electronic engine control unit in the reverse order of removal.

10. If it is necessary to remove the bracket for the electronic engine control unit, use side cutters (or cut with a knife) the clamp for securing the wiring harness ...

Note.
The clamp is disposable.

11 .... and take the harness aside.

12. Remove the four bolts securing the bracket to the inlet pipe ...

13 .... and remove the bracket.
14. Establish the bracket of the electronic engine control unit in the reverse order of removal.

It was once on the block from the X18XE-1 that two contacts from the flash drive to the ceramic (thinner than a hair) came off. Nothing, soldered - a microscope and a soldering iron with a very thin attachment + a tripod.

But, IMHO, all the same, all such shares do not go for a long time.

ICE control units OPEL

ECU (brains) OPEL (1998-2010 in fact represent an open-frame microcircuit (with rare exceptions) and cannot be repaired.

All the repairs that the workshops can offer are the restoration of fallen off aluminum conductors between the microcircuit (the one that is filled with gel) and the pins of the connector where the wiring is connected (see photo # 1). Since all 128 (. This is how many conclusions the ICE control unit has) conductors are in the same conditions, then all the rest will be unsoldered after the first. Everyone who is familiar with a soldering iron knows that without active fluxes, aluminum is poorly soldered (you already know about the disadvantages of active fluxes), so repairing on "knees" is not effective. At the factory, contact welding is used in the manufacture of the ECU.

By the way, when they hear the phrase “hybrid ECU” in reputable workshops, they immediately hang up.

An alternative to buying a new (and therefore more expensive) unit can be the installation of a BU unit.

A typical misconception is that you must definitely buy an electronic engine control unit (brains) for an Opel with the same number as on your car. This is not true. All blocks, with rare exceptions, are interchangeable, they need to be "flashed" for your VIN and configuration. Modern ECUs, which are produced to replace the old ones, have completely different numbers. The main problem of all ceramic ECUs is their dilapidation, constant temperature drops and vibration lead to unsoldering of the contacts inside the block. When buying a used block, you must look at the release date. Chances that a used block will last longer with an ECU manufactured 5 years ago than a 15-year-old

You can buy an Opel ECU depending on your preferences:

1 Programmed - ECU (reset was made to the block, your VIN is registered and configured) - you need to bind the block to the immobilizer, you need a competent specialist with the equipment. You must know your Carpass (Secret Code)

2 Kit (a bunch of ECU + chip + immobilizer) - you just need to install the kit on the car.

For cars (1998-2004), it is advisable to buy a set consisting of 3 elements or, if desired, a zeroed block (made by RESET):

1 KEYCHIPS (the chip is in the key)

2 keychip reader (immobilizer)

3 ECU (engine control unit - ICE brains).

For cars (2004-2010) it will be a reset block (made by RESET) or a block with a known secret code (CARPASS). You only need to bind the block to your car (if you are in Moscow, this can be done in our technical center).

You will need CarPass from your car - a sheet of thick paper in the same format as a service book, which is issued when buying a car. If it is lost, it can be ordered through a dealer or deducted from the old ICE control unit or another unit.

For correct operation on your car, any ECU (control unit or new) must be reprogrammed for your VIN and vehicle equipment (type of box, presence of ABS, air conditioning, etc.).

Attention! "UNIQUE SERVICE", all units purchased from us will be adapted to your car, ie VIN and vehicle configuration will be registered. The presence of dealer equipment and dealer software allows you to do this. You just have to install it on your car.

The following information is required for programming

2. Engine model (read PTS)

4. Availability of ESP (Heading Stability System or Traction Control)

7. Gearbox type (automatic or mechanic)

Write what kind of malfunction you have, the diagnostic results, on the basis of which you came to the conclusion that you need a unit.

Send order to ru or to the form below

If you want a new block, we will link it to the immobilizer and program it for your car. Easitronic control units are always available.

1 month warranty for the unit (for testing and installation).

Opel ECU firmware

If you bought an Opel unit during disassembly, we will be able to decode the ECU, update the firmware to the latest version of not only the “brains” of the internal combustion engine, but also other electronic units.

Qualified technical assistance

If you have any questions - call, do not hesitate!

We work with regions (we will send the block by any express delivery).

The cost of the ECU is 10,000-17,000 rubles.
