hi i have the same problem.if you find a 02 simulator.please let me know where to get one.i have a4 2001 1.8L.i had hole in old (original) exhaust then cell came on.yellow engine management light on dash.so.had new stainless full system made.from cat back..bloody light came back on after two days.The diagnostic code said"Lamder sensor?pressure too low".i guess this is from having non standard exhaust.please...if you know how i can sort this prob out please email me at nick.koisser@tiscali.co.uk.cheers
