C220 CDI W204.008 2007
Error 203A, Circuit 87 and A10D00

Hi,
Someone out there with a black belt in electrickery you can make sense of those iCarsoft MB2 error codes and I quote:

"203A Check component N10/1 (Front SAM control unit with fuse and relay module) N10/1kl"

"Circuit 87 (Circuit 87 relay, engine) General error"

"A10D00 The power supply is low"

These errors may just be related. Just changed the Varta battery. Questions: Where are those parts, where can I buy them and can I just rip them out and plug new ones in? If only it were that simple.

Thanks. I only ever use the best fencing wire for my repairs!
