About this Turbocharger

The BMTS 40008457 turbocharger uses exhaust energy to spin a turbine that drives a compressor, forcing more air into the engine. More air means more power from a smaller engine, and turbocharger health depends heavily on clean oil.

Frequently asked questions

What are the signs of a failing turbocharger?

Loss of boost and power, a loud whine or siren sound, blue or grey smoke, oil in the intake pipes or intercooler, or boost-related fault codes.

What causes a turbocharger to fail?

Most failures come from oil problems, such as dirty oil, a blocked oil feed or late oil changes, and from foreign objects entering the turbine or compressor. Find and fix the cause before fitting the new turbo.

What should I replace along with the turbo?

Replace the oil feed and return lines or their seals, all gaskets and single-use fasteners, and change the oil and filter. Clean or replace the intercooler and pipes if the old turbo shed oil or debris into them.

Can I install a turbocharger myself?

It is an involved job with tight access and important oil-priming steps. Prime the turbo with oil before first start and let the engine idle to build oil pressure. An experienced technician is recommended.

How do I make sure this turbocharger fits my car?
