Highly recommend friendly & extremely helpful. My car was taken in for diagnostics and repaired the same day, I was expecting it to be a big / expensive problem but this garage was extremely thorough & honest and ended up costing a lot less that I expected.

Mike found the root cause of the issue and there was no problem with the filter itself. Mike rectified the issue and I collected my car the next day, amazing service and great people!!

What a great company, when I called them my car had previously been misdiagnosed at a different garage at a significant cost, when I spoke to Mike he asked me a lot of questions, and I dropped my car at a easy location, he had the car for a few hours and I had a full assessment report and he talked me through what was required, later that day my car was ready for collection dash light free!! Would highly recommend

Economy Tuning

With fuel prices continuing to rise, economy tuning has become an increasingly popular choice for drivers looking to reduce their running costs without sacrificing performance. At Hill Vehicle Services, we offer expert ECU recalibration specifically designed to improve fuel efficiency in turbo diesel vehicles. By optimising the torque curve, our economy remaps reduce the need for frequent gear changes and excessive accelerator input, allowing your engine to run more efficiently.


The result is a noticeable improvement in MPG, smoother driveability, and a more responsive driving experience — all without compromising engine reliability. Please note: Economy tuning is available for turbo diesel vehicles only.
