I purchased a new Audi TT Roadster (2015 model) in May 2015. A fault developed in July 2016 where the MMI sound interface stopped working and returned to the authorised dealer for repair. After a week I was told Audi would not honour the warranty claim due to "external influences" being 'leaves/grit/dirt' getting into the compartment that cannot be visibly seen/easily accessed leading to flooding by rainwater from the roof damaging the electronic units. I was faced with a bill of over £2,000! The car is regularly used and well maintained so beware this is an Audi issue and not a customer maintenance one.

The dealership have moved to reduce my payable to £150 but that still leaves me legally accepting this as a repair claim rather than warranty. After asking what will happen if it occurs in the future I was told it likely would and I would have to bring the car in every two months for checks to reduce the risk - this isn't a hypercar! I have also been told the roof needs to be in a state of transition (half-up) in order to access the compartment to clear debris - it doesn't state this in the owner's manual. As I see it, and am proving, this is a breach of the Sale of Goods Act 1989 where the buyer must be "in an informed position" when at the point of purchase. No one would buy a convertible that is subject to leaves falling on the car in non-visible/accessible places resulting in flood damage and large personal costs.

Pretty sure everyone should be made aware.
