Car has been in Audi over a week they have replaced the inlet manifold and knock sensors and still the hesitation issues are still there. I've now been told I need to put the car back to stock (again more of my time to drive 120 mile round trip) as they want to replace the ECU and can't until this is done. If Audi uk see see its mapped then this will get thrown out of warranty!
What do I do??? Get it back to stock and kick up? This is my 2nd brand new s3 in 9 months as the first one only lasted 250 miles with a faulty mecatronic unit (totally standard)
