hi all I hope someone can help?
I have just bought a 2002 a6 1.8t and have converted it to lpg but im stuck on the o2 sensor connection as mine has five wires (red,white.black,grey and yellow) and I don't know which one to connect the signal wire to also what type of sensor it is i.e lambda, wideband or uego and what voltage to set it to as the lpg software needs this for the autoadaption (ac stag 300 isa2). I hope this is an easy first post?

regards
mark
