T4 Alternator - 2.8 VR6 (AMV) (Also T5 Alternator - 3.2 VR6)

This replacement alternator is a high-output 150 amp unit designed for later Volkswagen Transporters, covering T4 models with 2.8 VR6 AMV engines, selected T4 Syncro 2.5 TDI models, and T5 Transporters with 3.2 VR6 engines. Built to OEM specifications, it provides reliable charging performance for vehicles with high electrical demand.

What this part does

The alternator supplies electrical power to the vehicle while the engine is running and keeps the battery fully charged. On VR6 and TDI Transporters—often equipped with additional electrical loads such as air conditioning, heaters, and auxiliary systems—a high-capacity alternator is essential for stable voltage and long battery life. A failing alternator can cause warning lights, flat batteries, or poor starting.

How it works

Driven by the auxiliary 6-rib V-belt, the alternator converts mechanical energy from the engine into electrical energy. It regulates output to a steady 14 volts, supplying current to the vehicle’s electrical system while recharging the battery. This 150A unit ensures sufficient output even at low engine speeds, making it ideal for vans used daily or for long-distance driving.
