We have developed the Turbocharger Diagnostic Tool to get your vehicle running again quickly after a breakdown. It tells you the possible causes when your engine shows failure symptoms. Often a defective turbocharger is the consequence of some other primary engine defect which cannot be cured just by replacing the turbocharger. However, with the diagnostic tool you can determine the true nature and extent of the trouble without any problems. Then we can repair your vehicle more quickly and at less expense – so an engine failure won't cost you any more time or money than necessary.
The turbocharger is designed such that it will usually last as long as the engine. It does not require any special maintenance; and inspection is limited to a few periodic checks. To ensure that the turbocharger's lifetime corresponds to that of the engine, the following engine manufacturer's service instructions must be strictly observed:
90 % of all turbocharger failures are due to the following causes:
These failures can be avoided by regular maintenance. When maintaining the air filter system, for example, care should be taken that no tramp material gets into the turbocharger.
If the engine does not operate properly, one should not assume that the turbocharger is the cause of failure. It often happens that fully functioning turbochargers are replaced even though the failure does not lie here, but with the engine.Only after all these points have been checked should one check the turbocharger for faults. Since the turbocharger components are manufactured on high-precision machines to close tolerances and the wheels rotate up to 300,000 rpm, turbochargers should be inspected by qualified specialists only.
