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 r…

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 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.
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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The BLS offers strong performance but requires specific maintenance for its FSI system. The main long-term concern is carbon buildup on intake valves, which is manageable with periodic cleaning. With strict adherence to oil changes and using the correct fuel, these engines can be very durable and reach high mileages.
The most frequent issues are carbon buildup on intake valves, high-pressure fuel pump (HPFP) failures, and ignition coil/spark plug wear. Moderate oil consumption is also a known characteristic. These are well-documented in Volkswagen service information and owner experiences.
The BLS engine was used in the Volkswagen Passat (B6, 3C chassis) from 2005 to 2010, badged as the 2.0 TFSI. It was also used in the first-generation Škoda Superb (B6, 3U chassis) from 2008 to 2010, also as the 2.0 TFSI.
Aftermarket ECU tuning is common on the BLS 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 its performance. Expect around 8.5-9.5 L/100km (30-33 mpg UK) in combined driving for a Passat. Highway cruising can yield 6.5-7.5 L/100km (38-43 mpg UK), while city driving will be higher, around 11-13 L/100km (22-26 mpg UK).
Yes. The BLS is an interference engine. If the timing chain were to fail (which is rare but possible), the pistons would collide with the open valves, causing severe internal engine damage requiring a major rebuild or replacement.
It requires fully synthetic oil meeting the VW 502 00 or 504 00 specification, typically SAE 5W-40. Using the correct oil is crucial for protecting the turbocharger, timing chain, and managing the engine's operating temperatures. Do not use 5W-30 LongLife oil.
