Reviews

What customers say

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.
Mr Christopher Mersom Volvo
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
Excellent job by the lads at jf automotive, had engine tune/ gearbox service and tune on my x5, would highly recommend and would definitely use them again!
