Dealer-Level Diagnostics at Your Local Independent Garage
Since 1988, JS Motor Services has been helping drivers in Minster Lovell and Witney with honest, accurate fault-finding and repairs. Today’s vehicles rely heavily on electronic control units (ECUs), sensors and modules — and our workshop is equipped with up-to-date diagnostic tools to communicate with these systems across a wide range of manufacturers.
We don’t just “plug in a code reader”. Our experienced technicians interpret live data, carry out guided tests and perform checks under real driving conditions to confirm the root cause of the fault. This means more accurate diagnosis, fewer return visits and better value for money.
Whether it’s a simple sensor fault or a complex intermittent issue, we’ll keep you updated throughout the process and only recommend work that’s genuinely needed.

- DPF (diesel particulate filter) warnings
- ABS, traction control & stability systems

What to do if a warning light comes on
If a warning light appears on your dash, it’s best not to ignore it. Some issues can lead to further damage if the vehicle is driven for too long, especially where emissions systems or engine lubrication are involved.
- Note when the light appears (cold start, under load, at speed, etc.)
- Avoid long journeys until the fault has been checked
- Call us for advice if the light is flashing or the vehicle feels unsafe
