MERCEDES SLK - W170 - Start Error

[CARPARTS]

Hi,

Before : Car drive without problems / owner removed odometer for km programming
After : re-programmed odometer back in car, now the odometer shows "Start Error"...

Immo is NOT in odometer , but only in FSB and ECU !

How is this possible, what could possibly go wrong or is this failure a coïncidence ?

Thanks for advises

check actual value-transponder on fbs ecu

solved !

it was the transponder-antenna, dammaged while removing.....

so the "start error" is logical and caused by not detecting the key-transponder !
