DPF sensor

[S2YOB]

Evening,

I have just purchased a C350 CDI but it keeps (every 4 days) going into limp mode.

When I read the codes it says "The lower limit value of component DPF sensor has not been reached"

I have changed the DPF sensor and all was good for four days, then tonight it dropped into limp mode again!

Any ideas

Nick

Could a previous owner of gutted the DPF?

Never getting to temperature, so the DPF isn't burning-off (regenerating)?

If it was a private sale, I would take it to Mercedes. You may soon have a nasty surprise if the DPF is empty . .

Thanks for the replies.

Car was purchased from a dealer and has a AA warranty.

Took car to a merc specialist and MB star is reporting No codes in engine or gearbox!

But they also reckon the car has been mapped!

Regards

Nick
