The Volkswagen AGL is a 2,771 cc, VR6 petrol engine produced between 1996 and 2000. It features a unique narrow — angle (15°) V6 configuration with a single cylinder head, dual overhead camshafts, and multi‑point fuel injection. This compact design delivered 125 kW (170 PS) and 245 Nm of torque, offering a blend of smooth power delivery and space efficiency for transverse engine bays.

Production years 1996–2000 meet Euro 2 standards .
The Volkswagen AGL is a 2,771 cc VR6 petrol engine engineered for mid-size sedans and coupes (1996-2000). It combines a unique 15° narrow-angle V6 layout with DOHC and multi-point injection to deliver smooth, linear power. Designed to meet Euro 2 emissions standards, it prioritises refinement and performance within a compact package.

The Volkswagen AGL was used across Volkswagen's Passat B5 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts for the Corrado variant-and no significant facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The AGL's primary reliability risk is failure of the internally mounted water pump, with elevated incidence in high-mileage vehicles. Internal Volkswagen Group service data noted this as a critical failure point. Neglecting to replace the pump during the timing belt service leads to almost certain engine damage, making proactive replacement mandatory.
Analysis derived from Volkswagen technical bulletins (1996-2000) and historical service records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The AGL engine is fundamentally robust and delivers smooth, reliable power. Its critical weakness is the internal water pump, which must be replaced with the timing belt at 80,000 km. With strict adherence to this service and regular oil changes, the AGL can reliably exceed 250,000 km. Ignoring the timing belt/water pump service will almost certainly result in a destroyed engine.
The most frequent and critical issue is failure of the internal water pump, leading to overheating. Timing belt failure if not replaced on schedule, ignition coil failure due to cracked housings, and oil leaks from the large valve cover gasket are also common. The water pump issue is well-documented and requires proactive maintenance.
The AGL engine was primarily used in the Volkswagen Passat B5 (3B) from 1996-2000, typically in GLX and V6 trim levels. It was also the final engine used in the Volkswagen Corrado (53I) from 1996 until production ended in 1998, replacing the earlier 2.9L ABV engine.
Yes, moderately. The AGL responds well to intake and exhaust upgrades, along with ECU remapping. These can yield power gains of 15-25 kW. More significant power increases are possible with forced induction (turbo or supercharger kits), but these are complex and expensive modifications for the VR6 platform.
Fuel economy is moderate for its size and era. Expect approximately 10.0-12.0 L/100km (24-28 mpg UK) in combined driving for a Passat. Real-world figures depend heavily on driving style, with highway cruising yielding closer to 8.5 L/100km (33 mpg UK). The Corrado, being lighter, may achieve slightly better figures.
Yes. The AGL is an interference engine. If the timing belt fails, the pistons will collide with the open valves, causing severe internal damage that typically requires a complete engine rebuild or replacement. This makes adhering to the 80,000 km timing belt (and water pump) replacement schedule absolutely critical.
The AGL engine requires oil that meets the VW 501 01 or 502 00 specification, typically a 10W-40 or 5W-40 semi-synthetic or mineral oil. Using the correct oil is vital for engine longevity. ACEA A3 is the minimum acceptable standard if VW-spec oil is unavailable.
