Hello

Strange problem after flat battery replacement on Mercedes (w204 2009) C180 kompressor . Car wont crank.
KEY is sending +50 signal but no turn over.
All Actual values in DAS are ok, except in engine ECU SIEMENS SIM271KE where in first dialog STARDIAG inform me that

ECU is BAD(DEAD) ,transport locked not authorized etc...and I cant enter ecu .

I dont have developer version.Is that mater????

[benzstop]

can you hear the steering lock operate? the key will always turn,even if the wrong key is inserted so that does not say much.Do the ignition lights come on? can you lock/unlock car using remote? if you can lock and unlock car using remote and key turns but no lights on dash,you may need to replcace steering lock.many problems with steering lock in this model

Wont loose key data like that, check pre fuse box and also go to control modules /front Sam/power supply / ins sensor and check voltage in actual values..compare ins sensor voltage to battery voltage and they should be the same.if ins sensor(located on ground terminal of battery) reads a lower voltage then ins sensitization faulty

[benzstop]

sorry,that shyould read ibs sensor faulty
