Cl203 Sportcoupé

[Kaurinho]

Hallo. My dad has a problem with his/my old Sportcoupé 2004 c220 cl203. Sometimes it woun't start. He just turns on cooling fan full speed and woun't crank or start. Turning key does nothing. After waiting some time it starts cranks like nothing happened. Any ideas? We tried diagnostic original one and no Errors to be found but he didn't manage to make connections to other parts of the car. the mechanic reminded himself few years ago he had an ML which did same thing. After changing Central Gateway it was gone. Now problem is also where is CG to be found? Can anyone tell me where should it be? Thanks

Still got problems with intermittent starting

I started a thread a while back where I thought my intermittent starting problems were related to going through deep(ish) water. I no longer think the water aspect is relevant but, I still have starting problems. First thing in the morning the car will start 1st time (2005 C220cdi coupe)...
