The 1.6-liter 8-valve Volkswagen ARM engine was produced from 1999 to 2000 and was installed on only two models: the Audi A4 in the back of the B5, and the VW Passat B5 co-platform to it. This is a Euro 3 unit with a mechanical throttle drive, a conventional mass air flow sensor and no EGR valve.
The EA113-1.6 series includes: AEH, AHL, AKL, ALZ, ANA, APF, ARM, AVU, BFQ, BGU, BSE, BSF.

Disadvantages of the VW ARM engine
- This is a very reliable and resource unit, and breakdowns occur at high mileage.
- The culprit for the drop in power is the fuel pump or fuel pressure regulator.
- Also, the cause of unstable operation may be air leaks or failures of the mass air flow sensor.
- The mechanism for changing the geometry in the intake differs in low reliability here.
- After 200,000 km, the engine begins to consume oil due to wear on the rings and caps.
