Typical signs of turbo failure include loss of power, smoke under boost, increased oil consumption or a whining noise.

Fitting Advice
We always recommend having your replacement turbocharger fitted by a qualified mechanic. Correct installation is essential to ensure proper fitment, reliable operation, and long service life from day one.
You can read our full fitting instructions here.
It is also essential that the root cause of the original turbocharger failure is identified before fitting the replacement. In many cases there is an underlying issue that also needs attention, such as a blocked DPF. This is one of the most common contributing factors, and fitting a new turbo without resolving it can place the replacement under unnecessary strain.
We also offer a professional DPF cleaning service if required.

Warranty Information
Unless otherwise stated, warranty is provided to the original purchaser for repair or replacement of the turbocharger for up to 2 years from date of purchase or 12,000 miles (whichever occurs first). Warranty covers the turbocharger for faulty workmanship or components and does not extend to damage caused by misuse in fitting or operation.
The reason for failure of the previous turbocharger must be rectified prior to fitting a replacement. Air and oil filters, engine oil, gaskets and the oil feed pipe need to be changed or replaced. Proof of purchase of components may be required to support any claims.
Proof and date of the original purchase will be required before considering any warranty claim, and the unit must be returned complete. Any attempt to dismantle or repair the unit will invalidate the conditions of warranty. Warranty does not cover any cost of labour or materials required to remove or reinstall the turbocharger.
