Here at Fast Fit we can do most of the mechanical repair jobs on cars. However for some electronic repairs we will reluctantly refer you to the main dealer. In particular we get up to three deliveries per day from VW/Audi group (which includes SEAT and Skoda) and more specialised parts can usually be delivered within a day or two if they are in a UK depot. So even if your car needs a part that for example that only VW supplies, we can often get the part and fit it after getting a diagram emailed through from our supplier. Below is the schematic for the cooling system for a VW Golf that had a leak from a junction in the coolant pipes.
