Hi,
i tried to tune a Mercedes Sprinter 902 208 CDI (60kw) out of 12/2000 today. All went positive when writing the EDC15C6 with MPPS, but after this the car will not start (Display: Start error).
It even not turns the engine around.
When i read it with Mercedes diagnosis DAS, there is some strange behaviour, as i can't read the engine ECU, because DAS says, that Immobilizer is defective and needs to change. But i can access the Immobilizer ECU and nearly all tests are ok.
Of course car has had one problem before, as the key is not removable from ignition, so owner leaves it in and closes door with another key. But car drives before.
Tried also recovery with MPPS and KESS, but no help.
Me and my tuner are sure, that there were only maps readed and flashed, but maybe we triggered something inside Immobilizer?
Is it possible to remove this Immobilizer from car?
Maybe someone has experienced similar behaviour on such a car? Or maybe knows solution to get the car running again.
Thank you
Christian
P.S: DAS has info on "Start error" fault...i should learn transponder again. But i don't have this FDOK chiffre and also car says, it hal already 8!!!! keys learned!!!!
