Thanks for the info!
Sorry to be an ***, do you have any links, a google search brings up lots of varied links to oxygen sensor tools etc!
Would like to pick one up for the collection (money spend on tools is never wasted!).
Glad my B9 S4 is a. 3.0TFSI - such a great engine to have only been put in cars for 2years or so!
I can’t understand it - with the UK and Europe going massively anti-diesel, who is going to by a diesel S?. The people who can still justify them due to mileage are already in big diesel...
