Rest assured that it is not your driving style that's causing the problem - the 335i is a daily driver class car, which should be as reliable as most of them. It you want to learn about the fuel quality problem, you can search the forum, but it is likely that there never was any fuel problem. The fuel discussion started in 2007 when a few BMW dealerships allegedly at first refused to replace the failed HP pumps under warranty, claiming that the pumps were damaged by fuel that was not meeting the required specifications. If you want to look at hard data on fuel quality, they have been posted ( http://www.bimmerfest.com/forums/sho...d.php?t=435606). Most members of the forum agree that for those using reputable brands, there is no correlation between the fuel brand and the HPFP problem. |
What's interesting is that although there are claims that the % is very small, curiously there are 335's wholesaling for 19k, and SIB 12 55 06 is so detailed there's no way so many scenarios and FC's could have been documented from a small %. It takes experience to be able to put together such a SIB.
