What customers say

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
Arrived 8.30 Saturday morning, a technician armed with laptop tuned the gearbox,so now the truck changes earlier keeping the revs lower,I was a bit hesitate about having it done,but it's definitely better with no problems.
Mark Grindell Toyota
Had a gearbox remap on my T6 Volvo XC90. Shifts through the gears are now much smoother and I can def notice the difference in torque. Thanks folks.
