Having resisted the idea for a long long time, I would like to know for sure, how to LPG convert my 2.7T (Allroad 2000) and which brand kit is recommended for this engine. I've seen LPG'd 2.7's on Autotrader from time to time - so what's wrong with them ?
An Audi Specialist I use for maintenance says don't - he's seen too many poor conversion's on S4's. So my problem is I've an immensely well maintained 2.7T and would love it just that little bit more if it cost me a little less at the pump.

Any ideas?
