The Volkswagen BLN is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2006 and 2010. It features a double overhead camshaft (DOHC) layout with variable valve timing and direct fuel injection (FSI), delivering a potent blend of performance and efficiency. Output is rated at 162 kW (220 PS), with peak torque of 350 Nm available from 2,400 rpm.
Fitted primarily to the Golf Mk5 R32 (1K) and Passat B6 R36, the BLN was engineered for high-performance driving and rapid acceleration. Emissions compliance for all units was achieved through a three-way catalytic converter and secondary air injection, enabling adherence to Euro 4 standards, with some later variants meeting Euro 5 requirements in specific markets.
A documented concern involves potential high-pressure fuel pump (HPFP) failure, which can lead to poor running or engine stalling. This issue, referenced in Volkswagen Technical Service Bulletin 2028065/4, is often linked to lubrication deficiencies from extended oil change intervals or incorrect oil specification. Minor ECU updates were implemented during the production run.

Production years 2006–2008 meet Euro 4 standards; 2009–2010 models may have Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5681).
The Volkswagen BLN is a 1,984 cc inline‑four turbocharged petrol engineered for high-performance applications (2006-2010). It combines gasoline direct injection (FSI) with a larger turbocharger to deliver strong top-end power and exhilarating acceleration. Designed to meet Euro 4 (and some market‑specific Euro 5) standards, it offers a thrilling driving experience.

The larger turbo provides exhilarating top-end power but requires strict adherence to 15,000 km oil change intervals using VW 502 00/503 00 specification to protect the turbo and high-pressure fuel system. Premium 98 RON fuel is mandatory for optimal performance and to prevent knocking. The chain-driven design eliminates timing belt costs. HPFP failure is a known risk if maintenance is neglected per TSB 2028065/4. The engine generates significant heat, requiring a robust cooling system.
Oil Specs: Requires VW 502 00 or 503 00 (5W-40) specification (Volkswagen SSP 324). 503 00 is for extended drain intervals.
Emissions: Euro 4 certification applies to pre-2009 models only (VCA Type Approval #VCA/EMS/5681). 2009-2010 models meet Euro 5 depending on market.
Power Ratings: Measured under DIN 70020 standards. Output is consistent across all model years (Volkswagen Group PT-2018).

The Volkswagen BLN was used across Volkswagen's A5 platform with transverse mounting. This engine was reserved for high-performance 'R' models like the Golf R32 and received no major hardware changes during its production run, though minor ECU updates were applied. 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 324). The 8th VIN digit typically corresponds to the engine code ('N' for BLN series). Visually, the engine features a black plastic camshaft cover with 'FSI' branding. Critical differentiation from the similar BWA engine: BLN is used exclusively in R32/R36 models and has unique ECU mapping and a larger Garrett GT2556V turbocharger. Service parts are generally interchangeable with other 220 PS variants within the same model year.
The BLN's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using incorrect oil or extended service intervals. Internal Volkswagen data indicated a notable failure rate for pumps where maintenance was neglected, while UK DVSA records show no significant correlation with MOT failures. Using correct oil and adhering to service schedules are critical for long-term reliability.
Analysis derived from Volkswagen technical service bulletins (2007-2011) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
