DIY webasto bmw e39 repair

Can anyone have an instruction manual for Webasto? (otherwise everyone has some different opinions and experience of use).
Or who would clearly (competently) say:
1. The main purpose of Webasto.
2. Types, depending on the modification of the autos.
3. Principle of operation.
4. Programming options.
5. Care and maintenance.

Thanks in advance from all webasto dummies.

Perhaps there is still dependence on the number of salaries in the tank, tk. a couple of times sutra the car was cold and there was less than 15 liters in the tank, xs can also glitches, all the same not new

Definitely there is - if the fuel is on reserve - it does not work. I don't know how many the seven have, but the 39th has about 7 liters of the remainder.

Found links on the network where curious Russian guys took Termotop apart

I will summarize all your work: I would read the forum and understand that the pump is a very weak point there, and often fly. I also died, changed. Second, the diagnostics would show you everything, you can also check every element there without disassembling the webast.
Disassembly is always a hall of bolts, because the place is not very good for installation. Well, the second weak point is the brains, fail due to oxides and other things.

Hello again to the place.

P.S. How to check the board - a lot of information has also been written. Only where does such a desire come from, to check all complex electronics with improvised means, a tester and anyhow? Diagnostics in the form of the simplest K-line for 300 rubles will show you everything.

I do not argue that prevention is really a good thing, and in any case it is necessary. Now you will restore it and you will know that everything is in order and for several years I definitely think not to remember about it. And as for diagnostics, I mean that the keys responsible for starting the pump, or glow plug, or fan may not work on the brain board. Although these things themselves will ring and will be alive. Also, you will not see if the readings of the temperature sensor are correct, because there is a thermistor that does not like overheating and starts to fail. Either always or at some moments show 125 degrees (its maximum), respectively, the webasta will crash. Diagnostics can trace the weight cycle from startup to operation, or to an accident, but then with the formulation of why the webasta stopped working. View the glow plug temperature, the temperature of the temperature sensor, check the fuel supply, etc.

P.S. Pumps - there are substitutes and analogues. You can put something there. Not necessarily the original with the BMW badge.

P.P.S. There is a good topic about Webastu on neighboring forums, for example, in Belarusian. In the E39 branch, in the FAQ subsection. Only there are 140 pages, you can poke around until you read everything or find something)))

I read. And he made his own. Start from the end, they recently talked about pumps.

dauzh)) .. you upset me right .. there is all disassembly in full growth) But 140 pages is creepy! I started from the end - so there is a stupid dispute about nothing, moved to the beginning, there is the same thing only about another dispute. Unfortunately, today, when replacing the pump, I cut my hand with a fucking metal gasket, so I didn't have time to do anything (.
I'm postponing it until tomorrow.
normex thanks for the useful information!

With all the tools in place, the job takes no more than a day. There is nothing complicated, you just need care and accuracy - such a procedure can extend the service life for more than one year.Another important point - to mount the exhaust system well - it will be very unpleasant if it is not sealed or brought out - in this case, all gases will be under the hood and fender, and therefore in the cabin.

BMW E39 Flashing Webasto thermo top ZC Onboard Incident Log

Yesterday I was lucky to rewrite my webasta - Webasto Thermo TOP ZC

Webasto Thermo TOP ZC badge under the hood bmw e39

What did I get as a result of these manipulations? A lot of warm impressions every time you come to the parking lot to your BMW E39 and sit in an already warmed up car, now you boldly start up and head in the direction you need. In one warm-up cycle, Webasta spends about 100 grams of fuel, and this is 2-3 times less than warming up with a running engine, and you also save engine resource.

What did I get by flashing?

I got control of Webasto in my car interior. Now I have:

bmw e39 timers webasto
HEAT ON - Forcibly enable Webasto
VENT ON - Turn on the ventilation of the passenger compartment.
1 TIMER 2 - Two independent timers for starting webasto by time.

1. Forced inclusion of webast - HEAT ON

2. Forced activation of interior ventilation. - VENT ON

3. Two timers set at any time, which are triggered when the installation time coincides with the time of the on-board computer. - 1 TIMER 2

Now my vibasta starts up at a preset time and heats up the engine coolant and the interior for 20 minutes (blowing on the windshield.)

When the webasta is set to start, an asterisk is displayed next to the timer.

You can also just go down to your BMW, if you have not set the timer to start the webasta, but you know that you will need to go in about 30 minutes and turn on your webasta manually for one cycle (which I did right now :)).

Webasta will warm up the coolant, oil, and interior, but do not forget to warm up the automatic transmission before leaving.

Maybe someone will ask: What do you need to change your webasta?

5. BMW E39 and Webasto Thermo TOP ZC.

Other people have read after this article:

1. Found a little problemThis morning I found out that the protection is under the front right wheel.
2. Small accidentLittle Pichalka happened yesterday evening (08.02.2012).
3. BMW E39 contact oxidationMileage 247.7 thousand km. Date 27.02.12 Problem: Oxidation of contacts.
4. Replacing the xenon ignition unitWhen one door closes, the other is bound to open. That's just not.
5. BMW E39 Injector Repair ReportOnce I wrote an article not so long ago about INPA.

Owner BMW 5 E39 I called a specialized car service "PIK" and signed up for the diagnosis of the engine preheater system - Webasto. The reason for petition - Webasto does not work... The car has been traveling around the country for a long time, came off the assembly line in 2002, the mileage is almost 270 thousand kilometers. The BMW 5 E39 car is exposed to the lift, the diagnostician of the PIK specialized car service is ready to start troubleshooting. The owner of the car noted that the problems began after severe frosts, which were at the beginning of the year. Let's figure it out. The diagnostician's experience is more than 10 years, the reasons for Webasto's failure have long been studied.

The diagnostician of the PIK specialized car service connects the scanner. Computer diagnostics, carried out using Rheingold dealer software, can help you find the problem. However, the scan attempt was unsuccessful - no response. Either there is no power, or the motherboard ordered to live. The pre-heater is a small unit that is installed in the area of ​​the left front wheel and is connected to the cooling system, to the vehicle's electrical network and to the fuel tank. Therefore, the auto mechanic of the PIK specialized car service must dismantle the left front wheel and the locker. Then you can check the power supply, strip the wires and "terminals". The food comes in. After the work done, the diagnostician again tried to scan the system Webasto... To no avail. The preliminary diagnosis is “motherboard burned out”.Further diagnostics is possible only after disassembly. Based on his experience, the diagnostician of the specialized car service "PIK" recommended replacement of the engine preheater... The BMW 5 E39 car leaves the repair area of ​​the PIK specialized car service.
