After doing 80.000 M the engine gave up on me /ubbthreads/images/graemlins/cry.gif /ubbthreads/images/graemlins/cry.gif /ubbthreads/images/graemlins/cry.gif First diagnosis at nearest Audi garage: broken exhaust valve, which consequently damaged a substantial part of the engine. The damage to the pistons, cilinders etc seems to be that bad that the engine is beyond repair. /ubbthreads/images/graemlins/shocked2.gif Got three options: -sell and try to forget my S3 /ubbthreads/images/graemlins/cry.gif -have engine swapped for standard 210bhp block /ubbthreads/images/graemlins/frown.gif -have my tuner fit in a 225bhp block and restore it back to it's former output of 350bhp. /ubbthreads/images/graemlins/1luvu.gif I will get some more insights about prices etc tomorrow. Anyone have had this valve problems before?
