Frequently Asked Questions

Common Symptoms of Turbocharger Failure

Loss of engine power, slow or laggy boost response, excessive black, blue or grey exhaust smoke, whining or whistling noise, high oil consumption, oil leakage at the turbo seals, abnormal noise from the turbine or compressor, or boost pressure faults may indicate problems within the turbocharger.

These symptoms may also be caused by a clogged air filter, blocked or leaking intercooler, restricted oil feed, contaminated engine oil, exhaust leaks, boost-pressure sensor faults or other engine management problems.

Professional diagnostic testing is strongly recommended before replacing any turbocharger.

Important Diagnostic and Installation Information

Before replacing the turbocharger, a professional inspection should be performed, including oil-feed and oil-return inspection, air-intake and intercooler inspection, exhaust system inspection, boost-pressure testing, air-filter inspection and engine oil quality analysis.

If the previous turbocharger failed due to oil starvation, oil contamination or foreign-object damage, the oil feed pipe, oil return pipe, oil filter, air intake and intercooler should also be inspected and cleaned before installing the replacement turbocharger.

Installing a new turbocharger into a contaminated oil system or restricted air intake may result in repeat failure and additional engine damage.
