I have just dropped my car off at AmD Essex for them to take it to Pro Alloy Ltd in Suffolk.
There it is being used as a development car for the research and construction of a bespoke larger inter-cooler for the S3.
You can see their work here: http://www.proalloy.co.uk/
The car should be there for a week or two, only just got it back from Audi!
Spoke to the guy in charge Wayne, very helpful and knowledgeable.
Will keep the development posted here, pictures and info!
I think after this I can finally stop for a bit!
