You must be choking
After exchanging my wonderful Volvo 940 Celebration for a 2008/58 V70 diesel estate last November, I took your advice and have always run it on BP Ultimate diesel (as also my wife’s Golf), and both cars are driven to get well up to temperature to burn off the crap in the DPF.
I bought the car from the local Volvo agent Bells of Northampton at 35k miles. At 40k miles a message came up ‘Engine Service’ and I asked the garage what all that was about. I was asked if I had added any engine oil, which I had not. After taking the motor back and waiting around town for a couple of hours it was declared fixed. Doing a bit of persistent probing, I learned that the regeneration of the DPF dumps diesel into the sump and contaminates it.
This sounds horrendous but I am assured that it is not? As the car is coming up to the end of its 3-year warranty will the above incident have done any damage and is there anything else I should have checked over or looked for?

Extra diesel fuel is added to the engine to regenerate the DPF, but it cannot do this if the DPF gets clogged from too many short runs from cold or not running hot enough. Given your use of the car this should not have happened so there must be something wrong with a sensor.
