E70 35d US - EWS-Manipulation after dead Car Battery and all keys Lost - alrochmaro - 09-29-2024

Hello, I have bought an US X5 MY 2011 with the 35d engine. Unfortunately the keys have been stolen before, so no keys were left for the car. The previous owner stopped the engine due to strange sounds. Afterwards he wasn’t able to start the engine, because the battery was drained.

I checked at home the battery, it was completely dead, showing about 7 V. 

So replaced battery and took it to someone who made a key for me with his CGDI over OBD. 

After a few minutes the key was ready and everything in the car worked, ignition worked, starter worked. 

But even though the car cranked, it wouldn’t start.
Only one relevant error code came up 2E3C - so EWS manipulation or tamper protection. 

Tried to sync CAS and ECU, but without any chances to get it working. 

As it’s an CAS3+ it is not possible to just sync them, so what could be the issue here? 

I suspect that maybe ISN in CAS was corrupted by CGDI, even though the dealer says CGDI can not mess up any ISN. Probably because of the drained battery? 

Updated the car today with ÎŜ†Ä/P, but error still is there, car won’t start. 

Any ideas what can be done else to get this fixed? 

Thanks!
