Called back into the dealers today to mention the switch problem, the advisor told me it just screws in and takes a few minutes so i order the part.
He then asked if i wanted it fitting so i ask how much that would be (thinking he wouldn't charge as they missed it on the service) - £28.50

when i asked why it was so much as he said it takes a few minutes to fit (his words previously) he then said it's because the undertrays, etc need removing????
you can get to the switch from the top

picking switch up tommorow and i'll fit it myself - fecking stealers
