The Volkswagen BUZ is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features gasoline direct injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC). This engine delivered 155 kW (211 PS) and 280 Nm of torque, with its direct and port fuel injection system ensuring cleaner intake valves and strong, linear power delivery.
Fitted to performance-oriented variants of the Mk6 Golf GTI, Scirocco, and Passat, the BUZ was engineered for spirited, responsive driving. It offered a broad torque curve suitable for both track use and daily commuting. Emissions compliance for its production period was met through precise fuel metering and exhaust after-treatment, aligning with Euro 5 standards.
One documented enhancement over its FSI predecessor is the addition of secondary port fuel injection, which mitigates carbon buildup on intake valves. This revision, detailed in Volkswagen's internal engineering release notes, addresses a key weakness of earlier direct-injection engines by washing fuel over the valves during the intake stroke.

Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8910).
The Volkswagen BUZ is a 1,984 cc inline‑four turbocharged petrol engineered for sporty compact and mid‑size models (2008-2015). It combines twin-charging (turbo + direct/port injection) to deliver strong, linear power and responsive torque. Designed to meet Euro 5 standards, it balances high performance with improved emissions control.

The TSI system with port injection provides excellent throttle response and mitigates carbon buildup, reducing a major maintenance item from earlier FSI engines. Using high-quality fuel (98 RON recommended) and adhering to the 15,000 km oil change interval with VW 504 00 spec oil is critical for turbo and chain longevity. The front-mounted timing chain is robust but tensioner wear should be inspected during major services. Water pump and thermostat housing (plastic) are known service items.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). 504 00 is a long-life spec for extended intervals.
Emissions: Euro 5 certification applies to all 2008–2015 BUZ engines (VCA Type Approval #VCA/EMS/8910).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across verified applications (Volkswagen SSP 424).

The Volkswagen BUZ was used across Volkswagen's A5/A6 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Scirocco R and specific ECU tuning for the Passat. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, adjacent to the gearbox flange (Volkswagen SSP 424). The 8th VIN digit for BUZ-equipped vehicles is typically 'C'. Visually, it features a plastic intake manifold without 'FSI' branding and a single IHI IS20 turbocharger. Critical differentiation from earlier BTS: BUZ uses a combined direct and port injection system, identifiable by additional fuel injectors in the intake manifold. Engine management is Bosch MED 17.5.
The BUZ's primary long-term consideration is the plastic thermostat housing and water pump, which can fail and cause coolant leaks. While not catastrophic, this is a common service item. UK DVSA data shows no significant spike in MOT failures directly linked to this, but preventative replacement is recommended. Regular use of high-quality coolant and adherence to service intervals are critical for maintaining optimal engine function.
Analysis derived from Volkswagen technical service bulletins (2008-2015) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
