Diagnostics
Vehicle Diagnostics
Diagnostics means investigating the underlying problem, not simply clearing a warning light and hoping it stays off. We use modern diagnostic equipment alongside proper mechanical testing to identify the actual cause of a fault.
You'll get a clear explanation of what we've found, what it means for your vehicle and what your options are.
What you get from a proper diagnosis
- The actual cause identified rather than a guessed part swap.
- A written explanation of the fault in plain language.
- Costs discussed and agreed before any repair.
- Repairs carried out in the same workshop once you're happy.
