Take it back to the dealer under guarantee.

Hi Jason, it’s a S3 265bhp covered 57k, there is no real difference when driving no loss of power

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
