Please could anyone tell me........If my inlet manifold / swirl valves / swirl actuator are all knackered...would this prevent the car from performing the automatic re-gen of the DPF. I have had the car now for 7 months, and probably inherited the above problems, although I have never been aware of the re-gen taking place.
I do the right kind of driving for it to happen, ie. long motorway runs etc but no obvious signs of it ever having re-genned.................other than 2 static ones, via tech 2.
