Before you dismiss the title Tunnie, it's actually a pretty comprehensive How To, and probably applies to everything VAG make...

Thanks. 

But why link to a fault, I've already read up on it. But nice to know any feature I mention on my car will have thread on a faulty version posted up.

Nothing wrong with mine and looking at that guide I would never bother fixing it

I thought it was actually rather informative as it gives insight into what/where/how

And credit where it's due, at least you won't have to remove the whole dash to get at it...
