General DPF - not regenerating Please help

[motoring]

Hi All,

I own a S40 (2006) Diesel. The car has performed very well and I have been very happy with it until last year when my DPF filter clogged up. I had it cleaned at the service centre, only about 6 months ago - and now I have the same problem again.

I admit the car has not been on a dual carriage way - and most of the time it is simply doing "stop - start" journey in the city.

As soon as this happened for the second time - I took the car out for a long drive - and tried to push the engine to aprox 3000 RPM and 67 Miles/h for quite a while (30 to 40 mins). Unfortunately nothing happened. the car is still sluggish and dashboard light is still on.

I am thinking that the DPF regeneration is not kicking in - could this be true ? what can you guys advice?
Shall I take it for another long run ? could that be dangerous ?

Any suggestion/advice will be of great value.

Regards
Jeanu

Can you give us more detail on what engine you have? The Ford/PSA engines 1.6 and 2.0 4cyl diesels use an additive in the regeneration which causes ash build up and the DPF needs to be replaced.

Hi, I learned that an out-of-order-thermostat prevents engine temperature to reach the needed temp for regeneration to start.
Have You got the trouble codes read? eng.temp, dpf pressure gap...
A forced regeneration by dealer and/or reset of codes.

That's not entirely true. Can't speak for the 1.6 but the 2.0D S40 / V50 with the Powershift transmission does not use additive. These cars have a 'dry' system same as the D5.
