Replaced it already. Lambda is my guess but there 360+vat.
Looking for confirmation before I order as dealers won't take them back.
Running quaar rough.
 
davelegacy on here was very helpful to me. Send him a PM. He talked me through a lot of things on the diagnostics machine. More knowledge than myself.
 
Have you cleaned your MAF and checked for leaks(air filter box, intake ducting and so on).
 
As above



No a dealer wont take them back

In fact any major manufactuer will void warranty once opened

It simply needs to have live volatage readings read to make a correct judgement
