What We Do

Dealer-Level Diagnostics from £50

Modern cars rely on dozens of electronic systems working together. When something goes wrong, a warning light appears on your dashboard — but it doesn't always tell you exactly what the problem is. That's where diagnostics come in.

At A Star Garage, we use dealer-level diagnostic equipment to plug directly into your car's ECU and read the fault codes stored by its systems. We cover:

  • Engine management lights
  • ABS and traction control faults
  • DPF (diesel particulate filter) issues
  • Airbag and SRS warnings
  • Transmission and gearbox faults
  • Hybrid and electric vehicle systems
  • Sensor and wiring faults

Most diagnostic checks take between 30 minutes and 1 hour. We'll explain what we find in plain English, give you a clear quote for any repairs, and let you decide — no pressure, no obligation.

All makes and models welcome, including hybrids.

Common Questions

Diagnostics FAQs

We plug our dealer-level equipment into your car's ECU (on-board computer), read the stored fault codes, and interpret what they mean. We then explain what's wrong in plain English and give you your options.

Yes. We can clear warning lights, but only after we've diagnosed and fixed the underlying cause. Clearing a light without fixing the fault just hides the problem — it'll come back, usually worse.

Most checks take between 30 minutes and 1 hour, depending on the complexity of the fault. Some intermittent issues may take a bit longer to trace.

Yes. Our diagnostic equipment covers hybrid vehicles as well as petrol and diesel cars. We can read fault codes from both the combustion engine and the electric systems.

We'll explain what we've found and give you a clear quote before carrying out any work. There's no obligation — it's your call whether to go ahead.

If you have a warning light on your dashboard, we'd recommend getting it checked even if the car feels fine. Warning lights can flag issues that get worse over time and cost more to fix if left.
