Hi no way you will be blackballed as a non Audi owner, I as an ex Audi owner thought the same when mine went but due to open minded attitude of the moderators I have just been able to carry on, they all seem to realise as I do that all VAG model diesels operate the same way regardless of different engine designations, they even share a lot of the same DTCs and I would be more than happy to help you should you need it, just PM me, after all its a sad world when you can't help someone else, the small capacity TSFI units have to work a lot harder to get you what you want so longevity is not guaranteed and when you consider a lot of Audis, Q3,A3 share the same engine design you could still learn loads.
Steve.
