Hello all, I have a 2011 c220 cdi. For the last 1000 miles or so the engine won't rev past 3000rpm and the Amber engine light is on. I plugged it in to my code reader and the two codes stored are P2455 and P2463. Could this be a faulty sensor?
Thanks
Ally

The first one (code) refers to the particulate filter pressure sensor circuit being too high. ("A" circuit )
AND P2463 calls up the fact that your particulate filter is plugged up.
Result engine is stifled, no wonder it won't go past 3000 r/m!
On the face of it both codes/symptoms go together.
All the best

Yes, try changing the dpf pressure sensor. Delete all error codes and see if things improve .

Live data on that sensor is around 0.04 .

Why ppl are not even trying google fault code descriptions... If they are reading codes with close to decent reader, it will give the description. If not, it is already a lottery but at least if I am looking for help on forum, at same effort I would try to find Whatta heck those codes mean.

Good that someone did the extra job, and in addition could give more instructions.

Is it best to get a bosch one or buy genuine? Hopefully get the part number off the one in the car tomorrow and get one ordered.
