203A Error - N10/1 Relay??
Hi,
My MB2 diagnostic gives me the following error code:
"203A Check component N10/1 (Front SAM control unit with fuse and relay module) N10/1kl"
N10/1kl seems to be the Wiper Stage 1 and 2 relay, but the wipers work! Question 1: On the fuse/relay diagram for my C220 CDI W204 2007, that may be the relay marked "K", I am not too sure? "K" is certainly OK when I checked it with the multimeter.
"Circuit 87 (Circuit 87 relay, engine) General error" Q2: Another error message, perhaps related to the above. Q3: "A10D00 The power supply is too low" - checked alternator at battery, it is charging at 13.5V or so.
All I know is that the 87 output of any relay is going to horn/wiper/motors, etc. Anyone out there with a black belt in electrickery to help?

Thanks for that. Sounds like a lot of bucks to me! More questions: How do I link a relay/fuse diagram to the MB2 codes as the relays seem to be all described as N10 relays and possibly the last lower-case letter appears to indicate what it is, such as N10/1kl??
