possibly maf or lambda

iv had in the past 2 weeks bank one 02 sensor plus it fails on vag com, could this be due to it being de-cated and 2.5 inch allway thorugh or u think its the lambda packed up?

iv also had it running lean on vag com but then seem to clear its self so faulty lambda ?

have you still got both lambdas connected in the engine bay? it still needs both plugged in to create a circuit, but if its decatted aslong as theres one there unless the wiring was broken it shouldnt matter as it isnt reading anything.

still have the two mate and im 99% they both in the exhaust will double check, so as long i got one in the exhuast the other just sits in the bay wired up ye ?

well if you're decatted you'll not need to worry about b1 s2 as its the post cat, if it was b1 s1 then its likely the pre cat is on its way out.

heard that you can put spacer on it so you can move the sensor more out.so not so much of the sensor stick inside exhaust
