DPF regeneration

For VW owners the following may be helpful

On particular point though the ECU will only do a regen if the speed is above 38mph or 60 Km/h.

I did have a problem with the last car when the light started flashing. On that car a flash meant a problem rather than the need for a fast run which was the light staying on. I was confused as we had just towed from Chester up to Carlisle. I did book the car in when we got home and they said it was a faulty sender rather than an actual problem. What they did tell me though was that in these circumstances the coolant water can reach the sump so an Oil change would be needed and using it with the light on could cause further damage. I traded it in so do not know if any long term problems.....

Very strange, What car was it? As I find it very difficult to see how coolant water would get to sump just because the exhaust is restricted by over burdened DPF. Sounds like some one was pulling wool over your eye's

The car was a Mazda 6. They did have a problem with the 2.0 diesel at that time so getting rid might have been wise. I do agree I do not see how the water could get into the sump but I suspect it was them misunderstanding the leaking valve issue I think they had but I never took it further.

Was it water? The Volvo XC 70 D5 Gen 3 would increase sump level by over carry of fuel used for DPF regeneration. Mine never gave any trouble in that regards, although the thought of driving for 20 minutes at 2500 rpm would have created some difficulty where I live. That would be neigh on 80mph, or manually in a lower gear, which would still not give 20 minutes driving given the lanes and junctions etc. Hence my move back to petrol.

The car was a Mazda 6..

I thought the Mazda 6's trouble was allowing the sump to fill with diesel and raising the level so that the engine went into runaway.

It was over four years ago so may be my memory is fading.

Jag XF 3.0v6 diesel. 4 miles to work and back each way. Would expect that to hurt the dpf but I've had zero warnings or issues in the 2 years I've owned it. Oil level does not change. Towing the caravan must give it a good clean out & keep it happy. Best car I've ever had.
