Hi

My car has the engine management light on and after a scan its showing fault code P13DF.

Does anyone know what the fault can be? I have reset the code but 3 days later its back on again. My car drives perfectly fine and no other issues.

Thanks

It is as easy as google --- P13 DF Mercedes fault code ------ and bingo you got it! It has something to do with ad-blue level or sensor issue.
Cheers!

hi have same problem. My addblue injector was blocked had it cleaned and code still on .my car is 7 years old .got in touch with Mercedes and they said a recall is on my car for nox sensors .they will do a software update and change sensors if needed f.o.c even tho out of warranty. All I did was Google addblue recalls put vin no in and it tells you if your car is affected.
