I'd never buy another diesel car after our experience with the DPF filter problems, we had a 5 series up until last week, the DPF light came on 3 times in the 3 years we had it, the car had Full BMW history, we were told by the main dealer's to only use Shell advanced or the BP equivalent, to "give the car a good thrashing, once a month" and avoid short (under 10 minutes) journeys, huh?
I understand that diesel in the UK has a particular problem, in that, to meet the EU directive re 10% veg oil to 90% diesel this year, oil companies are having great difficulty buying veg oil in the quantities needed and have resorted to buying any old rubbish! I don't know how true it is though?
We have done a lot of driving in France, the fuel does appear to be better, but it may just be the faster roads and lack of traffic?
We were also advised at the last service, that DPF filters usually needed to be replaced after 80,000 miles, at a cost of £2,500.
Every year we had the BM we lost £2,500 a year depreciation
Apart from the filter problem it was an excellent car though
We sold the car for a really good price and last Wednesday bought a 1997 mk4 LS400 for £2k.
