C30 Electrics : Voltage supply issues

[hansC30]

Hi everyone,

It was the first day of snow here in Belgium and apparently my c30 2.0d does not like it one bit. While driving my radio stops working all the time and restarts. Sometimes works for 5 minutes sometimes for 10seconds. About 10 times in a trip of 1,5hours, a couple of lights in the dashboard light up for about half a second. I looks like anti-skid service is required is also on the dashboard then. This message also disappears within half a second. One of those times I felt a big "bump" in the engine (definatly not the road;-)).

So I got home, hooked up vida and got following errors (see attached image for extra info)
BCM-0058
Bcm-0118
CEM-8F24
ADM-E010
ECM-2135
CEM-DF11
PAM-E010
Battery was replaced very recently.

Anyone any ideas? :-)

alternator voltage too high? You need to measure the voltage across the battery terminals with the engine running .. should be around 14 to 14.5 volts

Just did, voltage was 14.57V

Perhaps it intermittently goes high as several of those codes indicate high voltage

It does look like that indeed.. I cleared the errors, started the engine and the errors stay out.. Will drive it tommorow and see what it does..

After 2 short drives of about 40km in total I had no issues with voltage.. I did get into limp mode a lot due too something with the accelerator pedal (ecm 2135) AP position sensor faulty signal. Always gone after restarting the engine.. Any ideas here?
