What Mechanical Investigation Involves

Some faults cannot be confirmed by electronic diagnostics alone. When the issue is physical — a noise, a vibration, an oil leak, a driveline concern — the investigation has to be hands-on.

Our mechanical investigation service is used where physical testing, inspection or partial strip-down is needed to confirm the cause of a problem. We work methodically through the likely causes, testing rather than assuming, until the fault is identified.

When You Need This Service

• Unusual noises — knocking, rumbling, squealing, rattling — that need tracing
• Vibrations at certain speeds or under load
• Driveline concerns — clutch, gearbox, driveshaft or differential issues
• Engine concerns — oil consumption, coolant loss, overheating
• Suspension and steering faults requiring inspection
• Brake-related concerns beyond a standard service check
• Oil leaks that require inspection to identify the source
• Faults where electronic diagnostics pointed toward a mechanical cause

How We Approach It

Before any strip-down work begins, we carry out a structured assessment. This helps ensure that any investigation is focused and proportionate to the fault. Where possible, we test the vehicle first — road testing, visual checks, and any relevant electronic data — before committing to physical disassembly.

Once the cause is confirmed, we provide a clear written report of findings along with a written estimate for the repair work required. You remain in control of how to proceed from there.

Combined with Electronic Diagnostics

Many faults benefit from both electronic and mechanical investigation. A fault code might indicate a sensor issue that turns out to be caused by a mechanical fault elsewhere in the system. We approach each vehicle as a whole, and we use whichever investigation method — or combination of methods — is most likely to confirm the cause accurately.

Transparent Process

We never carry out chargeable strip-down work without discussing it with you first. If investigation requires partial disassembly, we will explain what is involved, what it will cost and what we expect to find. You decide whether to proceed.

If the fault turns out to be more involved than expected, we contact you before continuing. No surprises.
