Brickfield are good, I think he's moved to Kent near Ashford, not Redhill but not 100% sure where. He used to be based in Thornton Heath so that could be him too.
I can also highly recommend Ricky Cox here, http://www.wonkydonkeyemporium.co.uk/" onclick="window.open(this.href);return false; He's a really honest bloke, quality work and knows his VW stuff and runs his business well, ie he does what he says he is going to do. I would definately give him a call as part of the process. He's in Chipstead, south of Croydon.
Good luck
Al
