The turbocharger is one of the most misunderstood products in the automotive industry. If the vehicle starts to emit smoke the turbocharger will invariably get the blame. It is this ignorance or lack of knowledge by the owners and even some fitters that makes turbocharger service a very difficult area to work in.
A turbocharger operates in an extremely harsh environment – 1050°C exhaust gas/turbine temperature and over 200,000-RPM rotor speeds are not uncommon operating conditions for an automotive turbocharger. Appreciating this will help you understand why a turbocharger will fail if the engine or supporting systems are not in good order. The main life-sustaining factor for a turbocharger is the lubricating oil, comparable to the blood supply for a human being.
Our Diagnostic Fault Finder will assist you to diagnose problems accurately and help get the vehicle back on the road. It gives you some possible causes when an engine and/or turbocharger shows failure symptoms.
More often than not a defective turbocharger is the consequence of some other primary engine defect which cannot be cured just by replacing the turbocharger. A turbocharger is only as good as the engine it is fitted to and the person fitting it cannot expect a new turbo to cure underlying engine problems.
