Diesel particulate filter
Hi I bought a Merc E class CDI 250 Bluefficiency Avantgarde ED 125, it has done 58k on the clock. I could see an engine management light and when i took it to local garrage and the diagnostics have confirmed the DPF is faulty and Soot filter pressure sensor fault. Can you please confirm do we need to change DPF for such low mileage.

You say your car has only 58k on the clock.
With regard to DPF it is not the mileage that matters but the 'type' of mileage.
DPFs don't cope well with city or short journey driving.

Is the car still under warranty? I agree with Pluto, you should get at proper diagnosis done, it could mean the difference between a $100 repair and a $4,000 repair.

Is that not a "proper diagnosis"?

Well, just using a typical scanner may not accurately diagnose a DPF failure. Your car is pretty low mileage, so I question a faulty DPF. It's more likely a bad sensor such as the pressure differential sensor or one of the air lines connected to it.
I got the impression from your post that the mechanic was recommending a DPF replacement, which is pretty extreme. So, I'm not sure if they just scanned it with their OBD2 scanner, which may or may not have the full propriety codes in it or if they did more investigation; i.e. blow out the pressure differential lines, clear code, reconnect, and see if the error returns.
Also, did think give you a print out or list of the stored codes?
