My sons 2.0 GTD (2015) keeps going into limp mode, seemingly at random.
I set up ODIS Service on my laptp and ran a scan, and found lots of faults...So deleted them and asked him to bring it back to me next time fault occurred, which he did.
Codes main I got were:-
There are plenty of other codes from other modules, but suspect they are a result of the car going into limp mode, rather than the cause.
So I have replaced the Camshaft Position sensor and MAP sensor. The Crankshaft position sensor should have also been replaced today but the shop sent wrong one, so this will have to wait, and I am about to order a fuel pressure sensor.
However I am concerned about the Reference Voltage"B" fault. Would this be triggered by one of the mentioned sensors failing, or is this likely to be the cause of all the alarms.
I suspect the ECU generates the 5V reference "B".
The car entered limp mode again a few hours later, and exactly the same codes were present.
All codes are sporadic, and no codes remain when cleared, and car runs 100% until going into limp mode.
Is anyone experienced in reading the output of ODIS scan, who could help me fine tune the diagnosis?
My son took his car to two VW garages and neither have been able to help him, one even said there were no fault codes to read, yet have charged him a small fortune in investigations so far!
Scan results enclosed.
Any help or suggestions warmly welcomed.
