The Volkswagen ARL is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2005 and 2008. It features gasoline direct injection (FSI), a single turbocharger, and dual overhead camshafts (DOHC). This engine was part of VW's effort to boost performance, delivering 147 kW (200 PS) and 280 Nm of torque, providing strong, responsive power for spirited driving.
Fitted primarily to the B6 Passat and Mk5 Golf R32, the ARL was engineered for enthusiasts seeking a blend of high performance and daily drivability. Emissions compliance for its production period was met through precise fuel metering and catalytic conversion, achieving Euro 4 standards as verified under VCA Type Approval.
One documented engineering focus was managing the thermal load on the high-pressure fuel pump, a component critical to the FSI system's operation. While not a widespread failure, service documentation (VW SSP 324) notes the importance of using correct fuel specifications to ensure pump longevity and prevent premature wear.
Volkswagen
Production years 2005–2008 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen ARL is a 1,984 cc inline‑four turbocharged petrol engine engineered for performance sedans and hatchbacks (2005-2008). It combines Fuel Stratified Injection (FSI) with a single turbocharger to deliver strong, linear power and responsive acceleration. Designed to meet Euro 4 standards, it balances high output with regulatory compliance.

The FSI turbo system provides exhilarating acceleration but demands premium unleaded fuel (98 RON) to prevent knocking and protect the high-pressure fuel pump. Strict adherence to 15,000 km oil change intervals using VW 504 00 specification oil is critical for turbo and chain longevity. The lower timing chain is generally robust but requires inspection if unusual noises arise. Carbon buildup on intake valves is a known characteristic of direct injection engines; periodic cleaning may be necessary for optimal performance. High-pressure fuel pump (HPFP) lifespan is directly linked to fuel quality and should be monitored.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). 504 00 is a long-life, low-SAPS oil.
Emissions: Euro 4 certification applies to all ARL engines (2005-2008) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Peak output requires 98 RON fuel (VW SSP 324).

The Volkswagen ARL was used across Volkswagen's B6 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Golf R32 for enhanced rigidity. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, near the gearbox flange (VW SSP 324). The 8th digit of the VIN for North American R32 models is 'R'. Visually, the ARL can be identified by its black plastic intake manifold and the "2.0 TFSI" badge on the engine cover. Critical differentiation from the non-turbo FSI (e.g., BPY): ARL has a visible turbocharger and intercooler piping. Service parts, particularly for the fuel system, are specific to the ARL and not interchangeable with other 2.0L FSI variants.
The ARL's primary reliability consideration is the high-pressure fuel pump (HPFP), with potential for wear under suboptimal conditions. VW technical service bulletins note that using lower-grade fuel can accelerate wear. While not a high-failure item, diligent fuel quality and maintenance make long-term reliability excellent.
Analysis derived from Volkswagen technical service bulletins (2005-2010) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
