What Is a Diagnostic Check?
A diagnostic check involves connecting your vehicle to specialist equipment that reads fault codes from the engine control unit (ECU). These codes help us pinpoint issues with:
- Engine performance
- Transmission systems
- ABS and braking systems
- Airbags and safety features
- Electrical components
- Emissions and sensors
Once we’ve identified the fault, we’ll explain the issue clearly and provide a transparent quote for any necessary repairs — with no pressure or hidden costs.
What Happens If I Need Repairs?
After your diagnostic test, our technicians will walk you through the results in clear, straightforward terms. If any faults or issues are identified, we’ll explain what they mean, how they affect your vehicle, and what your options are. You’ll receive a transparent quote for any recommended repairs, with no pressure or hidden costs.
Once you approve the work, we’ll schedule the repair at a time that suits you and carry it out to the highest standards using quality parts. Whether it’s a minor fix or a major repair, we aim to resolve the issue efficiently and get you back on the road with confidence. You can book online or get in touch with our team to discuss your next steps.
