I have a BMW X5 3.0d Sport Auto and have started using bio diesel. I was told after 2 weeks to change the fuel filter which I have. The car starts but will not get over 3000rpm. Dealer has told me that I should have flushed the fuel out before change but other people have have said not. Can you advise?
have the same problem?
