Any help in pin pointing this would be greatly appreciated. Had an oil leak for a while, getting worse now though. Seems to be down the back of the engine block near the turbo. Very hard to see though. Took it to the local VW specialist garage, who changed the timing belt, which was due anyway, and because he said he'd have to do that to look for the leak. Changed the rocker cover whilst doing this but said couldnt find the source of the leak. Took it to another VW specialist who said it was the camshaft seal, changed that, but still pouring oil. Thinking next step could be to take it the Audi themselves, but am avoiding this. Any clues as to the cause would be appreciated as spending a fortune on oil at the moment, even though it is getting a regular oil change as a result! Many thanks
