picked up my S3 today, however o2 sensor failed 10 miles down the road!!!! Can you bloody believe it!!! Drove up from Cornwal to pick it up and couldn't be ***** to come back in a week or two, (after they've fixed it) so took it with guarantee that dealer will pay for replacement part (and fitting) from local audi centre down here. gutted. car looks amazing, handles superbly (all new discs pads -stopping power is immense) apart from flooring it which csauses the stutter between 2500-4500revs. it still pulls really well unless i put throttle down over 50%, and cannot wait until monday/tuesday when my local dealer replces the oxygen sensor (which was only just replaced!) and I can see what it can really do! happy but at same time gutted!
