What customers say

Amazing difference on my VW Touareg after having the Gearbox Mapping done, to compliment the engine Map i had done. These guys are always efficient and know their stuff!. Highly recommended!
Lee Rundle VW
Took my Golf GTI for a DSG gearbox service and was greeted by a helpful receptionist who answered a few questions. Staff were very polite. Very happy with the work done. 👍
Tom Griffiths VW
These guys really know their stuff. I went there for a TCU gearbox upgrade which has made all the difference on my car, they were really competitively priced and helped advise me on a few other bits as well. I’m definitely going back there again for some more upgrades. I highly recommend these guys, not…
