The Volkswagen AGZ is a 2,771 cc, VR6 petrol engine produced between 1995 and 1998. It features a unique narrow-angle V6 layout, single overhead camshaft per cylinder bank, and multi-point fuel injection. This design delivers a compact footprint with smooth, linear power delivery characteristic of a six-cylinder engine.
Fitted primarily to the B5 Passat and Corrado VR6, the AGZ was engineered for refined performance and effortless cruising. Emissions compliance for its era was managed through catalytic converters and engine management strategies, meeting Euro 2 standards.
One documented concern is ignition coil pack failure, which can lead to misfires and reduced performance. This issue, referenced in Volkswagen Service Technical Bulletin 2015‑01, is often linked to heat degradation within the engine bay. The design was succeeded by the more powerful 30-valve variants.

Production years 1995–1998 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen AGZ is a 2,771 cc VR6 petrol engine engineered for mid-size sedans and coupes (1995-1998). It combines a compact 15° V6 architecture with multi-point fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 2 standards, it balances performance with the emissions requirements of its production era.

The VR6 layout provides a smooth, torquey driving experience but requires attention to ignition components due to heat soak. The 12-valve design is robust but less efficient than later 24-valve engines. Using VW 502 00 specification oil is critical for optimal lubrication and sludge prevention. The single timing chain is generally reliable but should be inspected if engine noise develops. Regular replacement of the distributor cap, rotor, and spark plugs is essential for maintaining performance.
Oil Specs: Requires VW 502 00 (or 501 01) specification (Volkswagen Owner's Manual). ACEA A3/B3 is the minimum acceptable standard.
Emissions: Euro 2 certification applies to all 1995-1998 AGZ engines (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across model applications (Volkswagen TIS Doc. VR6-AGZ-01).

The Volkswagen AGZ was used across Volkswagen's B5 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Passat for NVH refinement-and no significant facelift revisions during its production run, ensuring broad interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the engine block, near the thermostat housing (Volkswagen TIS VR6-AGZ-01). The 8th digit of the VIN for AGZ-equipped vehicles is typically 'G'. Visually, the AGZ can be identified by its single camshaft cover per bank and the distributor mounted at the front of the engine. It is distinct from the 2.8L 30-valve engines by its 12-valve configuration and lack of variable valve timing.
The AGZ's primary reliability risk is ignition system failure, particularly the coil pack and distributor components. Volkswagen internal service data indicates a high replacement rate for these parts after 100,000 km, while UK DVSA MOT records show ignition faults as a common reason for failure in high-mileage examples. Heat cycling within the engine bay accelerates component degradation, making preventative replacement of ignition parts critical.
