Hi there,

I have a W204 C250 CDI Auto with a potential blocked DPF with EML on, as well as Limp Mode.

Initially had an Intake Air System Leak (P2462), as well as P2463 - Diesel Particulate Filter Restriction - Soot Accumulation..

Garage (non-Merc) fitted a new intake hose from the dealer, cleaned the DPF and reset fault codes, then advised I take it on a long motorway run with revs circa 2500-3000. I've done this several times with no effect (EML also back on and showing P2463).

Ever since, the car will not rev/accelerate above 3000 RPM, no power/kickdown/use of manual mode so assume it's in Limp Mode.

I've read it could be the DPF sensor/MAF etc. so was wondering if anyone could recommend a specialist in Leeds/West Yorkshire with Star to get a better idea?
Or is there anyone on here that has access to Star that can force a regen / or recommend the best route to take?
I believe iCarsoft MB V2.0 can also force a regen but not sure what allowance it has for soot levels before it does so.
There is of course the DPF removal route which I don't want to go down, but has anyone got any experience of doing so on this particular engine alongside a Stage 1 Re-map?

Thanks

Cleaned dpf then take it for a high rpm long drive , doesn't make sense , it's clean !


I'd do the dpf pressure sensor next as they're rife and have had several part revisions .

What concerns you about dpf removal ?

as above - change the sensor and use icarsoft to adapt it . otherwise it wont fix the issue.

Did the garage remove the DPF to clean it, can it be cleaned properly without removal?

Proper cleans are with dpf off the exhaust .
