VW Passat 2.0cr CBAB edc17cp14 won't start, OBD write failed

by **Finseth-K27** » Sun Jul 09, 2017 3:53 pm

Hi.

I really need some help.

I tried to write a file to my fiends car through OBD with KESS, it failed and now the car wont start.
Properly it is Tprot locked.

Before that, I read the original file through OBD, and wrote it back again with no problems.
But now it is properly locked.

Afterwards i have put the ECU to boot mode with kess tricore module, where i have made a "backup file read" and a "normal read"

I have read something about creating a restored file from the three files i just mentioned above.
Hopefully one can guide me in a right direction or help me creating a restored file so the car can start again.

Thanks in advance

I have attached my files.

3 files means FULL BDM.

I have now read out some files with MPPS V18, maybe they can help me better?

I bet you used protocol 198.

For this type of car always use protocol 501.

Give me your id, and i will send you the original file,

With the file I sensed you, you have to use recovery on protocol 501 and your car will work again

Thank you for helping me.

The problem was solved about 15 minutes before that you brought me the files. But thanks anyway. I appreciate that you took your time to help me.

The problem was solved with this guide which I found in another thread.

=================================================================
Problem: ECU VAG EDC17CP04/14 blocked writing MOD by OBD (so called EEPROM crash)
caused by: ECU remain in programming mode.
1. Read IROM / XROM and EEPROM in bootloader mode.
2. Fix IROM/XROM using bootloader readout and OBD ORI readout (you will probably need to paste part of map zone and chk/RSA zone)
3. Write fixed IROM/XROM by bootloader (do not touch EEPROM!)
4. connect ECU to the car and write repaired IROM/XROM (same used for bootloader) by OBD.
It will automaticaly fix eeprom problem.
Resolved

=======================================================================

I did not fix the iRom by myself. To do that I got help.

I hope that this can help some other who runs in to the same problem ;)
