Engine Diagnostics & Repairs

Warning-light diagnosis, performance issues, cooling system and oil-leak investigation.

About this service

When an engine warning light appears or the car simply does not feel right, we investigate methodically using professional diagnostic equipment and hands-on experience, then explain our findings before recommending any repair.

What this covers

  • Engine warning light diagnostics
  • Performance and drivability issues
  • Engine fault investigation
  • Cooling system issues
  • Oil leakage inspection

Common warning signs

  • Check-engine or engine-management warning light
  • Misfires, hesitation or loss of power
  • Overheating or coolant loss
  • Oil spots under the car or a burning smell
  • Unusual noises on start-up or under load

Why it matters

Early diagnosis often means a simpler, less costly repair, and it helps prevent a small fault from damaging other components.

What we typically inspect

  • Stored fault codes and live data
  • Ignition, fuel and air-intake systems
  • Cooling system, hoses and radiator
  • Gaskets, seals and sources of oil leaks
  • Mechanical condition relevant to the symptoms

The exact checks depend on your vehicle and the symptoms you describe.
