Engine light on. Loss of power

[Mbstarz]

Hi the engine light has come on and also have loss of power to car when flooring it. Could this be a DPF issue, or should there be another warning light specifically for DPF.

It's a 2005 c220 cdi coupe.
(Not sure if it has a DPF)

It's previously has a turbo hose replaced by previous owner. Could it be the turbo?

Many thanks

It could be many things from a faulty sensor to air filter to air leak swirls flaps to fuelling problem. In the absence of anything obvious, I would take the guesswork out of it and have it plugged into STAR and save money in the long run…check the air filter first though!
