Hi ,This is the story: I have an Audi a4 8e quatro 1.8t
0261208228 and 8E0920900 CLUSTER RB4. and only one working key. When i try to mess with kilometer with vag & can comander 1.4 full china sh*t it makes the def fault.

I found a file from this forum i put it and def fault gone ,but i lost immo and car doesnt start no more.
The file i found have the login code. What else do i need and what is the procedure to sync the key again and one more that i have buy?
Pls help.

You damaged the crypto area with odometer and immo information. You can not load another RB4 crypto dump and make it work.. You will get DEF and Error on display. Every RB4 crypto has an unique crypto mask. The only way to repair is with specific RB4 tools via OBD2. Repair via dump IS NOT possible.

Otherwise, your only hope is if you have a early RB4 non crypto (2001/2002). You can only use another dump only if your RB4 is an early non crypto version, but your chances are very slim.

You have to re adapt new dash to ECU with Vag-Com/VCDS, then adapt keys... so you need both PINs: for the ECU in the car and the new dash (which you apparently already have).

This might help:
