The Volkswagen BLS – Petrol is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2005 and 2010. It features gasoline direct injection (FSI), dual overhead camshafts (DOHC), and a single turbocharger. In standard form, it delivered 147 kW (200 PS), providing strong, linear power delivery characteristic of the FSI technology.
Fitted primarily to the Mk5 Volkswagen Passat and the Škoda Superb, the BLS engine was engineered for refined performance and responsive acceleration. Emissions compliance for its production period was met through precise fuel metering and catalytic conversion, aligning with Euro 4 standards.
One documented concern is carbon buildup on the intake valves, a known characteristic of early direct-injection engines without secondary port injection. This issue, addressed in later EA888 engines, can lead to rough idle or misfires if not maintained. Volkswagen issued technical guidance for periodic intake cleaning procedures.

Production years 2005–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen BLS – Petrol is a 1,984 cc inline‑four turbocharged petrol engine engineered for mid‑size sedans (2005-2010). It combines gasoline direct injection (FSI) with a single turbocharger to deliver responsive, linear power and strong mid-range torque. Designed to meet Euro 4 standards, it balances performance with contemporary emissions requirements.

The FSI system delivers strong, linear power but is prone to carbon buildup on intake valves due to the lack of fuel washing over them. This requires periodic professional cleaning (every 60,000–80,000 km) to maintain smooth idle and prevent misfires. Using high-quality, Top Tier fuel can help mitigate deposit formation. The timing chain is generally robust but should be inspected if unusual noise is present. Oil changes must use VW 502 00/504 00 specification to protect turbo and chain components.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). LongLife 04 5W-30 is not approved for this engine.
Emissions: Euro 4 certification applies to all 2005–2010 BLS engines (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across documented applications (Volkswagen SSP 324).

The Volkswagen BLS – Petrol was used across Volkswagen's B6 platform with longitudinal mounting. This engine received minimal platform-specific adaptations and was shared with the Škoda Superb. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, near the transmission flange on the intake side (Volkswagen SSP 324). The engine code is also listed on the vehicle data sticker, typically found in the spare tire well or on the driver's door jamb. Visually, the BLS can be identified by its plastic intake manifold and the "2.0 TFSI" badge on the engine cover. It shares its basic architecture with the BWA and BPY engines; differentiation is confirmed by the specific engine code stamping and ECU software.
The BLS – Petrol's primary reliability concern is intake valve carbon buildup, a common trait of early FSI engines. While not typically catastrophic, it leads to drivability complaints and requires specific maintenance. High-quality fuel and adherence to service intervals are critical for long-term smooth operation.
