Diagnostics
Dealer-level diagnostics use manufacturer-grade tools and live data analysis to pinpoint faults accurately — the right diagnosis first time, without guesswork.
Diagnostics explained
Modern vehicles are complex, and a generic code reader rarely tells the full story. Our manufacturer-level equipment reads live data, module-by-module fault information and hidden parameters that many garages can't access.
That means we identify the real cause of an issue first time — saving you the time, money and frustration of replacing parts on a hunch. Diagnostics are also the essential first step before any tuning, confirming your car is healthy and ready.

Diagnostics — your questions
What can dealer-level diagnostics find?
Live sensor data, module-level fault codes and manufacturer-specific parameters that generic readers miss — so we identify the true cause of a fault.
Do I need a diagnostic before a remap?
We always health-check a vehicle before tuning to confirm it's in good order — it protects both your car and the results of the remap.
Can you diagnose a fault another garage missed?
Often, yes. Our manufacturer-level tools and experience frequently pinpoint issues that generic diagnostics cannot.
How long does a diagnostic take?
Most diagnostics are completed within an hour or two, though complex intermittent faults can take longer to reproduce and confirm.
Do you fix the faults you find?
Yes — once we've pinpointed the cause we can carry out the repair, or give you a clear quote and explanation if you'd like to decide first.
