Have a high mileage (chauffeur)
e250cdi (om651) which went into soft limp mode about 2 months ago.
First scan threw maf fault P010162 and gearbox auxiliary pump fault P0C1C13, maf cleaned and gearbox pump replaced. CAR STILL IN LIMP MODE.
Second scan threw MAF and P0c1c13 check component Y58/15, Both maf and secondary sensor replaced. codes cleared. STILL IN LIMP MODE
Third scan threw P227906 air leak detected and P0C1C13 again, mechs couldn't locate any obvious leaks so made the call to replace inlet manifold.
Fitted manifold with new seals to parts that needed to be removed inc EGR but when scanned after completion P227906 was still there and car still in soft limp mode.
At the end of my tether trying to fix this air leak, the y58/15 was there for the first 2 scans but cleared after manifold replacement.
Have sent the car to another mech to throw some fresh eyes at the problem but can anyone offer any suggestions as to where else the cause may be?

You have multitude of codes for different faults. Guess what, all these parts in the car NEVER fail at the same time.
So, what is common between these all…the Central Gateway (CGW).
I had this happen with my S550. All sorts of errors but none of them saying anything about the CGW.
BenzNinja pointed me to the right direction. I found the bad connection with no solder. I soldered them and no problems since.
I don’t know how E-class CGW module is but I would check it out.
