I have got my A3 TDI 170 booked in for a service this saturday. (Job lot as there is only 200 miles between oil, main service on computer) Whilst its in been serviced I have thought about having cruise control fitted. I have seen a lot of info on here about it, fitting yourself etc. However I am worried that if I do it myself, I will end up with a load of errors etc. They have quoted me £149 for the service, too include long life oil, filter, pollen filter and inspection service. (No fuel filter as this was replaced in October 2012 when the cambelt & W/Pump were replaced. However, the quote for the cruise control seemed a little steep £227.95p If I am correct in thinking that this is expensive, I will not bother and will just get the service done as I am happy with the service cost. Then, I will find another way of getting the cruise control fitted coded etc. Any help is appriciated.
