335d on Bio Diesel?

blue-coupe · 03-03-2009, 03:25 PM

Is it possible to run (or convert) a 335d to run on Bio diesel?

Thanks.

I know the VW TDI can run on a mix of 10-20% bio-diesel to the petro-diesel stuff, def not more then that or you run the risk of clogging the high pressure fuel pump and/or injectors, which is what happened to the TDI we had made some batches of Biodiesel and the guy filled his whole tank with it, big smile on his face, all the time the automotive instructor was telling him not to go over a 1/3 of his tank (he didn't listen, he just wanted a free tank)

well 3 months later he was bringing it in to clean/replace the HP pump

now I have not read anything yet on the BMW's 335 D model so take everything I say with a grain of salt

I heard we DO NOT use any biodiesel contained fuel in BMW vehicle. ULSD ONLY

The owner's manual says no more than 5% biodiesel (B5).
