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)

**wiski** · 21st April, 2015, 06:13 PM

Write by boot , let the tool make chks.

**bugarcek** · 21st April, 2015, 06:44 PM

Still error at the end and car does not start

Your original boot mode backup you can't write it? I can help with this....

**bugarcek** · 21st April, 2015, 07:43 PM

I do not have original boot mode backup... I boot mode read after obd fails.

You can try to write these file

**bugarcek** · 22nd April, 2015, 09:29 AM

Does not work. Is there any way of getting all read (eeprom plus flash) And immo off the flash?

EDIT: I load again kire106ka file via boot mode and noticed, that glow plug light comes up. But car did not start, after that I load the same file again via obd and car just started. Impressive....

kire106ka THANK YOU VERY MUCH
