Had my dashboard lights flashing? Not sure what's going in. Photos of lights and diagnostic attached.

Lights flash intermittently but regularly. First time coming across an electronic fault like this in my 7 years ownership.

From the fault codes, it looks like there is an issue with one or more of the CAN bus networks; possibly a break in a wire or a loose connector or a bad module. The regular flash is probably one of the modules trying to communicate, failing, then trying again after it times out. Look for the easy issues first, broken wires or loose connectors.

Did you manage to get this sorted? My 2012 w204 amg estate used to do this and it became a real headache, the culprit was the air vents in the boot (drivers side/offside) beneath and behind the pull out cubby. The vents allow moisture into the car as well as fresh air, unfortunately one of the SAM (ECU) units is in the firing line for the moisture! I sprayed everything liberally with WD40 and blocked the vents with some blue roll....happy motoring for the last couple of years! Hope this helps 🙏 ☺️
