My Mercedes C180K SE Classic - 4 door saloon, Auto, 2002 reg.
Unlocked the car got in put the key in ignition, turned to engine on, engine started but lost most of electrics, i.e dash display, indicators, wipers, cruise control, electric windows, fan, air con, steering wheel controls. Head Lights, brake lights and internal cabin lights work but that's about it.
So I turned engine off and turned key to position before engine start and all electrics are fine, everything works but as soon as I turn key to next position,(engine start) electrics go off again.
After turning off and removing key and trying once more every thing was ok, i.e engine on and all electrics working. So drove to work parked up, came out after work put key in and same problem, turned off and on 3 times and everything ok, drove home parked up, next morning same problems again, but this time after turning on and off about 20 times all electrics stayed off, ahhhhhhhhhhhh.
Left it for a day and next day tried again, same problem but managed to get it all working after 5 attempts.
Have checked all fuses and relays in cabin, engine bay and boot all look ok, no corrosion as far as I can see and its now driving me up the wall.
Someone has advised taking it to a Mercedes specialist so they can run a diagnostics check, but before I go down this route,(the costly one) has anyone come across this problem and if so can you please offer advise. Thank you.
