Hello everyone,

My friend, the Yellow Angel, just dropped me off at home in my car... It was a really great day today icon_wink.gif.

Nachdem ich meine Sommerreifen endlich drauf gezogen habe wollte ich eine kurze Proberunde drehen. Als ich dann eine Kreuzung ĂŒberquert habe ging der Motor einfach aus. Ich hab versucht Ihn wieder zu starten allerdings orgelt er nur springt aber nicht an. Die Rohrzuleitung zu den DĂŒsen hab ich kurz eine abgeschraubt um zu wissen ob da noch Diesel kommt. AHe's coming.

Back home, I immediately connected the VAG-COM and had to witness a strange sight.

In almost all control units (transmission, ABS, instrument cluster, comfort system, etc.), the error "...sporadic communication with the engine control unit" appeared. When I clear the errors and restart the engine, some of them reappear. I've attached a log file. Maybe you have an idea.

It should also be mentioned that my engine control unit once had a defect (with hairline cracks and cold solder joints) - and it also has a chip tuning modification.

Sure, no problem. Here's the translation:

"Thank you in advance."

A 2.5 TDI without ABS and not a station wagon... that's something new icon_wink.gif.

Please provide a complete record, if you're going to.

Then, please code the number 19 (the gateway) to 00006.

And then we'll get a complete scan, PLEASE with a...
Readable formatting.

While the errors in lines 08 and 46 are also silly, they are completely irrelevant to the problem.
Personally, those in 46 would still bother me icon_wink.gif.

Thank you for the quick response.

I'm just going to grab my laptop and take a look.

By the way, it's a combination with ABS icon_biggrin.gif.

I've shortened the log file a bit to make it more readable. I'll be back in a moment...

Okay, here's the complete log file as saved by VAG-Com:

Unfortunately, the number 19 cannot be encoded as 00006; it always reverts to 00005! Could this be related to the workshop code?

Okay, that's bad luck. I tried to change the encoding again. However, I made a very slight typo. Now it shows "00007" as the encoding, and I can't change it anymore icon_eek.gif. Originally, it was "00005"...

Please take care of the error in the engine control unit (ECU) first.

Apart from that, 00007 is correct on your end, that was my mistake... so the 'incorrectly coded' message should be able to be deleted.

My problem is that it's either the fuel injection pump or the engine control unit (ECU) that's broken.

"This strange issue with the track switch mechanism didn't appear from the beginning. It only started happening after we unplugged and replugged the ESP connector. The engine control unit has had so many problems and has been repeatedly repaired or soldered... it's a never-ending story."

"Before that, I was getting almost every possible error code from the engine control unit (ECU), including communication errors. Isn't that strange?"

I only want to fix the car one last time, then it will be sold. I can only get 6500 icon_biggrin.gif for it, which is what I can get for a running car.

Then I would probably lean towards switching to MSG.

This morning, after the engine was cold, I checked the values 01 and 19 again.
Today, things are different.

Here is the 19th one.

Does that change anything about the story?

Generally, this is typical for a faulty pump control unit, but in those cases, the errors are not "sporadic." Since your main system control (MSG) is also a potential source of problems, I would try to obtain a replacement from exxx or borrow one somewhere.
