The Volkswagen ANJ is a 3,189 cc, V6 petrol engine produced between 2005 and 2008. It features a dual overhead camshaft (DOHC) design with 24 valves and electronic fuel injection. This smooth and powerful unit, part of the VR6 family, delivered 184 kW (250 PS) and 320 Nm of torque, using variable valve timing to optimize power and efficiency across the rev range.
Fitted to performance models such as the Golf V R32 and Passat (B6), the ANJ was engineered for high — revving perform…

Production years 2005–2008 meet Euro 4 standards .
The Volkswagen ANJ is a 3,189 cc VR6 petrol engineered for compact and mid-size performance models (2005-2008). It combines a narrow-angle V6 layout with 24-valve DOHC architecture and variable valve timing to deliver exhilarating power and a distinctive exhaust note. Designed to meet Euro 4 emissions standards, it balances high performance with drivetrain refinement.

The Volkswagen ANJ was used across Volkswagen's Golf V and Passat B6 platforms with transverse, front mounting. This engine received platform-specific adaptations-different engine mounts and accessory brackets for the Golf R32 versus the Passat-creating minor parts differences. 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 ANJ's primary reliability risk is timing belt failure if not replaced at the 90,000 km interval, with elevated incidence in high-mileage or neglected engines. Volkswagen internal data indicates that belt failure almost invariably leads to bent valves. High thermal loads from the 250 PS output increase ignition coil failure rates, making preventative maintenance critical.
Analysis derived from Volkswagen technical bulletins (2005-2008) and owner club technical archives (2005-2023). 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 ANJ engine is generally very reliable and robust when properly maintained. Its main critical service item is the timing belt; failure is catastrophic. Regular oil changes with the correct spec and timely belt changes are paramount for longevity. Many well-cared-for examples exceed 200,000 km with minimal issues beyond standard wear items.
The most frequent issues are timing belt failure (if not serviced), ignition coil pack failures (due to high output), variable valve timing (VVT) solenoid clogging, and intake manifold flap motor failure. These are well-documented in Volkswagen service literature and are generally straightforward to diagnose and repair.
The ANJ engine was primarily used in the Volkswagen Golf V R32 from 2005 to 2008 and the Volkswagen Passat (B6) 3.2L V6 from 2005 to 2008. It was the high-output 250 PS variant of the 3.2L VR6 engine for these models.
Aftermarket ECU tuning is common on the ANJ platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is moderate for a 3.2L V6. Expect around 20-24 mpg (UK) (approx. 12-14 L/100km) in mixed driving for a Golf R32, depending heavily on driving style and vehicle condition. Highway cruising can yield better figures, while city driving will be higher consumption.
Yes. The ANJ is an interference engine. If the timing belt fails or jumps, the pistons will collide with the open valves, causing severe internal engine damage. This makes adhering to the 90,000 km replacement interval absolutely critical.
Volkswagen specifies oil meeting VW 502 00 standard. A high-quality SAE 5W-40 synthetic oil meeting this spec is ideal. Using the correct oil is vital for protecting the hydraulic lifters, VVT system, and preventing sludge buildup in the narrow oil passages of the VR6 design.
