Hi all, new member and new pug owner, have a 2006 307 Hdi, very pleased with "new" car, but, have wiped out the FAP tank and want to suggest an outrageous idea followed by a plea for help. Since a new FAP tank etc will cost $1000 plus and since it seems to be the reason why bio-diesel is not possible, has anyone out there advice on how I might "disable" the computers warning/ shut down function when it senses that the clean out of the catalytic convertor has not occurred.?? Excuse me if I'm not making sense, but I've only been able to piece this chain of logic together by inference, having visited UK dominated websites where no one seems to talk directly about the subject of "waste veggie oil", or mostly about how it hasn't worked for them(and these are 3 years plus posts). My neighbour is using WVO in a Landcruiser so I have a source of fuel, and since I don't have a FAP tank ???? Am I ??
