C220-2011 multiple organ dysfunction!!!
Hi everyone. My 1st Post, so here goes!
It's about my previously delightful to drive 2011 C220 diesel Auto Estate!
I hope you can help!
Initial issue was engine management light with poor acceleration and gear change at higher revs than normal + burnt exhaust smell.
Local Merc guy plugged in diagnoser tool but no diagnosis, so reset and ok for a week.
Since, same issues came back. So I bought a diagnostic thingy which gave errors of SOOT ACCUMULATION IN DPF, + LOW VOLTAGE AT BOOST SENSOR A.. (makes sense about the DPF as a lot less motorway driving over the last year). Tried 2 lots of DPF cleaning additive.
So I reset and book into garage 7-10 days time... But immediately, engine light on + ABS + ESP + HOLD FUNCTION + RUN FLAT INDICATOR + CRUISECONTROL/ SPEEDTRONIC all inopeartive + THE ORIGINAL ERRORS!
Any ideas? Are any of these things connected (ie like a domino effect?),. Or any other suggestions?
I look forward to your comments and suggestions!
Can still drive it ok!

Hello and welcome to the forum! What code reader are you using? Is it a generic OBD2 one or one specific to Mercedes'? It seems like you have some gremlins in your electrical system. I would make sure that all the fuses/relays are as they should be.
