Just thought id let you know the old chariot is booked in monday for a new timing dampener/tensioner, time up and a smoke test for vac/turbo leaks at IVC Leeds.
I have had a couple of problems with power and the cam sensor showing up even when replaced and I had an annoying rattle from the belt side at 1200-2000 rpm.
Told the bloke and he had a quick look n listen, and said the dampener had shafted which in turn could nock the timing slightly causing the cam position sensor to show fault and run lean causing the performance issues. But he did mention leaks (boost) as you all have done in the past so he will do a smoke test whilst on with it.
They are charging £192 labour which is killin me as i like to do most things myself but dont want to touch the timing on this as ill prob bugger it up lol. Then 60 -70 for the part which I mentioned gsf do em for £50 and he said they use genuine audi so I didnt argue.
Ill let you all know the outcome as in performance on monday, Then next month I think it will be time for the old remap
