Diagnosis and Inspection Reports

Suspect a problem with your turbocharger?


Engine light on? No power? Smoking? Whining? These could all be signs of a faulty turbo.

Driving with a damaged turbocharger could destroy the engine and be dangerous. It is therefore important to seek immediate help for a damaged turbo. We are able to assist with the diagnosis of suspected turbo problems and can help to identify the reason for the damage to the existing turbo before replacing it. Book an inspection with Recoturbo and our specialists will perform a visual and benchtop inspection to check your turbo for issues that affect its optimum operation. Our specialist diagnostic equipment allows us to quickly identify the precise cause of the problem, which will then be detailed in a tailored inspection report.

We also offer an inspection and reporting service to diagnose faults with actuators; our full written report for each inspection offers tailored advice on your repair and servicing options.


How to recognise turbo failure


Engine power loss

Signs of a failing turbo can include slower acceleration or the failure of your vehicle to reach speeds it once could.

Engine noise

When under boost a failing turbocharger may make a loud, distinctive whining or whistling noise that is similar to a dentist’s drill or ambulance siren (if the compressor wheel is damaged). If you begin to hear unusual noises from your engine it’s worth booking in for an inspection.

Increased oil consumption and/or leaking oil

If you notice that your vehicle is consuming more oil than normal or is leaking oil this could indicate turbo failure.

Dashboard warning lights

The computer diagnostics of most modern vehicles will pick up faults with turbochargers. If the check engine light is illuminated, a diagnostic check is needed in order to confirm whether a turbo failure has been identified.

Black, blue or grey exhaust smoke

Oil could begin to leak into the exhaust system if the turbo housing is cracked or internal seals are leaking. As the oil burns, a dark distinctive blueish/greyish smoke is emitted from the exhaust. The smoke is most noticeable when engine revs are higher following a period of idling.
