Glow plug light is flashing, CCS does not work, this is the only one DTC. After clearing it comes back after restarting ignition. Car is stock, without any modifications, how far I know. Any ideas what direction to dig, what parts or circuits to check etc are welcome.

That one is a head scratcher. Even the extended info for that fault has nothing more than, "Invalid Data Received FromAnti-Lock Brake System Control Module". But no clue why.

There are couple TPI's for gasoline engines, according those TPI's the ECU FW update should solve the problem. Can't find TDI related similar TPI.

SW is already quite high with tdi-fix.

I would look into undocumented adp channels that need to be confed according to base engine pr code. Unfortunitely B7 abs doesn't have them in label file. If i get a chanche I will look them up from my memos.

Thanks, golfi_vend, will wait for some news from You. Have located used ABS module, will have it handy for testing next week. BTW AQ module production is cancelled, it is superseded by BM already in 2012, car is MY2014 :confused:

A061,7,is engaged. Check the Data Plate for the Engine Type/PR-Code.
A061,9,0 = PR-D2D/D2L/D4X/D4L/D34/D38/D42/D48/D67/D91/D93/D94/DB0/DE2/M92
A061,10,1 = PR-D4X(With 1AS)

Maybe some of them are existing in original label file, but I know I added some to my own file.

If checking the Adp channels in 03 doesn't resolve this you might want to re-code 01 and 03 back to the original values.

Sorry for giving feedback so late. This issue was solved a lot of months ago. The car just visited my workshop with another problem and I remembered that I haven't told the Forum what was the problem :confused:
I found an additional aftermarket immobilizer sitting on powertrain CAN and messing up data exchange... Customer didn't told me that he have such device installed... :banghead:
