Thanks for the replies, seems our Solus syystem at work can reset it and also read the control units in depth!!
I know what your saying about dealer servicing etc but it really doesnt bother me, id rather do it myself knowing that its done properly without worrying about the car being with them etc. Service is done its cost me a genuine filter a sump plug and the correct long life oil less than £40, the books stamped with a VAT invoice to back up the work/labour and a correct SEAT service sheet filled in so there is no issues for warranty.
Infact ive done SEAT a favour by also replacing the faulty mirror switch which otherwise would have been warranty.
