I posted this on another tread about the fuel filter and possible blockage. I don't know why we should expect BMW to do anything different as it is all about money is it not!!!!!! To get into the tank just use a drift and a hammer. Works fine Cheers Replacement filters are not available as BMW has decide to claim that they are a life time filter. They will supply if you have to replace your fuel pump at a cost of $700AUS. This may sound incredible but I had to replace my fuel pump(contaminated fuel) after 35,000 K's BMW Australia wanted $700 for the unit or I could buy a Bosch for $150. No guesses which one I chose. I then need to replace the Mahle fuel filter. Mahle have them in stock but will not supply as they have a contract with BMW. BMW dealers will not supply as there is no part number unless you buy the complete unit for $700 AUS. I have complained to BMW Australia and they will not supply or permit Mahle to sell the product as it is against BMW policy. I spent two hours reverse flushing the filter to improve it as a last resort. At this point I am unable to get a replacement. If any one has more luck than me and can get a BMW dealer to purchase direct from Mahle I would appreciate being in the loop.
