MERCEDES W210 E_CLASS CRANKING PROBLEM

[ngakson2002]

Hello Mate,

Please need suggestions of what could be the problem regarding the following experienced with a Mercedes E-Class W210.

1) ESL Unlock >>>>>> Ok
2) Key Turns in the EIS >>>>>OK
3) Instrument cluster comes ON >>>> OK
4) But no Cranking noise from the Starter motor (in fact, starter motor does not crank the engine)

Furthermore, i have noticed that following several attempts ON and OFF of the key, at times, the starter motor will crank the engine for not more than 10 seconds

Best Regards

Always problem with sync between EIS and ECU. Virginize ECU and teach in with DAS !

it is ecu fault very common on e class follow starter solenoid wire if comming from ecu surely need to replace ecu
