    My s3 has so far eaten 2 brand new bosch lambda sensors in 12 months.

    What can be causing this? Also i think it may be down to fueling as the car once upto temp will drop the revs to near stalling when gearing down and the clutch isnt engaged, also the exhaust does smell rich.

    Now avlo's coming over tomorrow for me to log his car and i may do mine so what are the best blocks to log for fuel, timing and boost?

    Get it on a dyno dani... need to see what the AFR is doing...

    Sounds like it could be running rich... have you still got the N249/N112 plugged in? is the rear lambda plugged in also?

    I know mate, should be on one, on the 17th of march, with mine been narrowband i cant log these via vag-com can i?

    N112 is as i remember when welly disconnected it, it messed his fuelling up, the n249 is disconnected though, that should matter should it?
