Audi=No fault code, no idea
In the same boat Mark.
My feeling is with mine its a total cut out, momentary but total...vibrates through the floor as it misses, its not a single pot so unlikely to be coils or plugs. took the Revo off today and it was fine on a test run of 20 miles then just took it 2 miles to the local shop and its farting about again under load at 3krpm ish. Least i now know its not the map as its running std now. seems totally random which makes it imposable to demo to the Audi techs unless i am very lucky. I look at you and MG and Cheese and several others all trying to sort this out and it reminds me of my 3.2 where a dozen of us tried to sort out its problems because Audi couldn't or wouldn't except there was anything wrong. Right now i am thinking of selling it. Just dont need this crap again for another 3 years.
Ibis white Revo S3 and now matching Vivaro LWB HR 2900 :-)
Many people are alive because its illegal to shoot them.
