Hi there,

I found your unanswered post on this forum concerning P3028 code - and issues with wiring and your throttle bodies on you Audi S6 V10.

I am having the exact same issues as yourself with my S6 - its at a point where we cant work out the cause of it, the auto electrician is heading down the replace the ECUs path....did you ever get to the bottom of it? We have rewired and checked the TBs and that hasnt made a difference. Sounds like I, like you, have spent a butt load on this car so any help would be hugely appreciated.

Im way down in New Zealand so there are hardly any S6s here - which is why im reaching as far as I can

Many thanks

Neil Chappell
