Mark,
How did you determine a knock sensor fault?
Did it show on diagnostics, or did you have pinging?
I ask, as I get pinging from the S8 under moderate load in 3rd gear acceleration (labouring engine).
I also have cracking in at least one of the knock sensor plugs, and I've been wondering if one of them might be faulty?
I only use 98RON and often add octane booster, especially for trips.
