Produced between 1996 and 2001, the 2.3-liter 10-valve Volkswagen AGZ 2.3 VR5 engine was mounted longitudinally on the Passat B5 model and transversely on the Bora, Golf 4, and Seat Toledo. This power unit was given a different AZX index after the cylinder head was upgraded to a 20-valve one.
AGZ, AQN, and AZX are members of the EA395 series.

Disadvantages of the VW AGZ engine
The high fuel and lubricant consumption of all VR5 power units is well-known.
The timing chain is not very resource-rich, and replacing it is costly and challenging;
Air leaks or dirt on the throttle are typically the cause of the engine’s unstable operation;
Additionally, the engine frequently worries about electrical issues: a number of sensors malfunction; in this case, the valve cover is integrated with a gasket and completely replaces itself in the event of an oil leak.
