Sure enough, they agreed with me but declined to do this as warranty work; they said that owing to the car being re-mapped it was now operating outside of it's performance parameters, therefore the discs, clutch and entire drivetrain would not be covered.

The 'Master Tech' apparently test drove the car and said it was the quickest car he'd ever driven



I've got MRC to thank for his comments there.
The dealer did say that even putting replacement Audi discs and clutch in would probably prove to be a false economy and I tend to agree with him on that point as we know the discs are prone to warping and that the clutch isn't the strongest it could be.
In fairness to the dealer, they did say that they wouldn't have a problem covering this as warranty work but Audi GmbH now request a full print out of the car's diagnostics with any warranty claim and if they saw mine, they would have rejected it straight away. That's what I was told.
Do I try and argue this with Audi UK? Have I got a leg to stand on? Probably not.
So, regarding the brakes, I've got it booked in with APS to have Brembo's fitted up front and I'll probably opt for a Sachs clutch kit too, albeit at a later date but soon.
The warranty on the car expires Jan 2010 but I've no regrets in having had done what I have by MRC. It's honestly given me an animal of a car!

What are your thoughts guys?
