IDENTIFYING TURBO FAILURE

 Noise that varies with engine speed and load could be a failing turbocharger,

or a damaged intake hose/intercooler.

 Excessive oil consumption can result from worn seals within the

turbocharger, often as a result of worn bearings. This leads to…

 Blue smoke from the exhaust. If this is not remedied, the catalytic converter and diesel particulate filter (if fitted) will also need renewal – adding considerably to the parts bill.  Black exhaust smoke can result from a lack of boost, causing overfuelling. This increases DPF loading. Causes may be a turbocharger fault, a leak of induction boost from a split pipe, or a punctured intercooler.
