Some years ago BOSCH Denmark sent out a letter and a poster to the BOSCH workshops, warning against all kinds of Alternative fuel(= non-fossil-fuels), including RME and FAME, which was specifically mentioned. They refused to cover any damages coursed by non-appropriate fuels, and forwarded the warranty question to the car manufactory, if they accepted Biodiesel, such as VW. I suppose that BOSCH Denmark just forward the message from the German headquarter.
Last year in June Spiegel Online published an article "No more release for Biodiesel", informing that VW had stopped the biodiesel release for the new Touran, I suppose the 2.0 PDI 4 valve/cyl engine. The reason was not the fuel it self, but fuel quality problems. http://www.spiegel.de/auto/werkstatt/0,1518,254679,00.html Niels > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf > Of John Hayes > Sent: 27. september 2004 15:31 > To: [EMAIL PROTECTED] > Subject: Re: [Biofuel] 2004 VW Jetta TDI > > Keith Addison wrote: > > I see you still haven't looked at the page I referred to, which you > > said needed updating (which it doesn't), so I referred you to it > > again > > Actually, I have read it and in fact have referred others to it on a > regular basis.
