So,went to Cadwell park on Sunday to watch the racing, it was a wash out and car parks were water logged! When I went to leave got stuck on the wet grass and tried turning ESP off to help traction. No beuno! No matter what I did with the button it wouldn't turn off.
Had a look on eBay for a button and it was a minefield, from a Chineseum special for £8.95 to Lithuanian seller advertising them for over £60! So I went to local VW dealer Crowsons of Spalding and got a genuine VW one for £35. The design has been replaced to one with a skidding car rather than the ESP OFF text, replaced in 2011.
