1974david Posted February 17 Author Share Posted February 17 Hi Jason, it’s a S3 265bhp covered 57k, there is no real difference when driving no loss of power Quote Link to comment Share on other sites More sharing options...
1974david Posted February 17 Author Share Posted February 17 Possible engine was steam cleaned as was spotless, spark plugs unknown can’t see anything in the bills history, is camshaft adjustments a costly job not that it matters as I can still take back the car and has a 6 month warranty, as the dealer is 4 hours away they will foot the bill at my independent garage, I was just worried that after I put in the injector cleaner in the light stayed on and I had made a bad move Quote Link to comment Share on other sites More sharing options...
