Passat edc17, problem with ecu after obd writing

**bugarcek** · 21st April, 2015, 02:57 PM

Hello

I have problem with Vw passat 2.0 tdi 140 hp manual 2009 year.

ecu hw: 03L907309

I read this ecu with galleto via obd. All was ok. I made egr off file and write it without a problem via obd on ecu.

Now after 3 months I tried to do also some dtc off on this ecu, I used my old obd read file, mod it and write back to ecu. Than I get error at end of writting and car does not start. (Customer was on official service 1 moth ago, he told me now)

Now I attached ori file readed by obd 3 moths ago and my full boot read.

Thanks for any help

I think your file egr off is wrong ..
Depending on what maybe the problem is the miscalculation of cks in the second writing ..
you try to write the file that worked before though egr is not off to 100%

Yes... If knew before that car was at the dealer. I would not do that... What should I do now?

Tprot not active. Maybe if you can check with VCDS date of last flashing (if it was flashed at dealer)
