What does this all mean?

Post by uk786 » Sat May 01, 2021 6:31 pm

Hello

As per the subject title I'm totally lost as to what all the data really means. My car is a 1.6tdi mk6 Golf. I have been having issues with the car often going into limp mode at what seems random times. The workshop fault and glow plug looking icon appears on my dash.

I was thinking it maybe is a dpf or egr issue? The mileage is 99k.

Thanks and appreciate the work!

There something strange in this picture, the soot mass calculated value clearly is impossible and also time/distance since las regen value are very high.
Moreover if you report strange engine behaviors, I think there is something faulty in the system, but it's pretty impossibile to understand where is the problem seeing a picture.
First of all you should verify if the data given by the app are correct; your engine ecu version could be not compatible with the app giving wrong values, it's a rare case but it's already happened with other engines. The best would be using an official diagnostic software, of course. If this check confirms the strange data, a complete system diagnosis is recommended.

Have you already checked for errors in the ECUs? Usually this kind of problem generates many errors in the ECU log.

Thanks for the quick response. I see what you mean. I will try using the app again this time with a different OBD2 device. Shall report back.

There are no errors or engine lights on the dash. When the car does go into limp mode it says workshop fault or something like that with a glow plug like icon lighting up. A restart of the engine and it's back to normal.

Just another question: have been your ECU chip tuned? I ask this because an engine working in recovery state without any warning light on (and no errors in the log) is a common case that happens when the tuner removes all the diagnostic functions in the ECU to prevent any problems, for himself of course.
This is a common way to complete a poor job and pretend it's perfect.

I have no idea. I have only had the car for about 7 months. :?
