P244A. Again?

[g shilling]

Hi, had this fault a few months ago, goes LHM and when you rev it acts like the car is in neutral (I mean the engine Rev very freely whiles driving along!) turn off and on fault clears! Replaced DPF sensor with genuine one from MB but this is the first time the EML has come on. At a loss. Serviced three weeks ago and no fault codes stored

Not necessarily the same fault code being the same component failure.

Serviced where exactly ?
