VW TDI turbocharger. Restore your TDIs full power with new turbocharger assemblies from Mahle. Turbochargers are subject to extreme temperatures and as the miles pile up, the internal bearings and seals wear out. This new variable nozzle turbo (VNT) comes as a complete assembly, including the exhaust manifold, and wastegate, ready to bolt on your TDI.
The VW ALH TDI turbocharger is integrated into the exhaust manifold and sold as a complete assembly. When you install the exhaust manifold and turbocharger you should make sure to install new gaskets and nuts on the exhaust manifold. You may also find that the studs in the cylinder head are too corroded to put new nuts on; so pick up a few new studs to make a secure connection to your engine.
