The Volkswagen BWV is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2006 and 2010. It features a cast‑iron block, aluminium head, dual overhead camshafts (DOHC), and variable valve timing on the intake. This FSI (Fuel Stratified Injection) engine delivered 147 kW (200 PS) and 280 Nm, offering a blend of performance and relative efficiency for its era.

Volkswagen
Production years 2006–2010 meet Euro 4 standards .
The Volkswagen BWV is a 1,984 cc inline‑four turbocharged petrol engine engineered for performance hatchbacks and sedans (2006-2010). It combines Fuel Stratified Injection (FSI) with a single turbocharger to deliver strong mid‑range torque and responsive power. Designed to meet Euro 4 standards, it balances sporting character with acceptable fuel economy for its class.

The Volkswagen BWV was used across Volkswagen's A5 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Passat and specific ECU mappings for the Eos. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The BWV is generally robust with a strong bottom end. Its main long-term issue is intake carbon buildup, which is manageable with periodic cleaning. The timing chain is durable. With proactive maintenance (oil, HPFP follower, induction cleaning), it can be very reliable beyond 200,000 km.
Top issues are intake valve carbon buildup causing misfires, high-pressure fuel pump (HPFP) failure often linked to cam follower wear, ignition coil failures, and turbocharger (K03) bearing or wastegate problems. These are well-documented in Volkswagen service information.
The BWV was primarily used in the Mk5 Golf GTI (2006-2009), Jetta 2.0T (2006-2010), Eos 2.0T (2006-2010), and Passat B6 2.0T (2006-2010). It was also found in the Audi A3 2.0 TFSI (2006-2008) producing 200 PS.
Aftermarket ECU tuning is common on the BWV 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.
Real-world fuel economy varies greatly with driving style. Expect 25-30 mpg (UK) in mixed driving for a Golf GTI. Careful highway driving can yield 35+ mpg (UK), while aggressive driving will drop it below 20 mpg (UK). It's not known for exceptional economy.
Yes. The BWV is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very robust.
Volkswagen mandates oil meeting VW 504 00 and 507 00 specifications, typically a 5W-30 synthetic. This is critical for protecting the turbocharger, timing chain, and high-pressure fuel pump. Using the correct oil is non-negotiable for longevity.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
