VOLKSWAGEN BKR engine (2005–2008) – Specs, Problems & Compatibility Database

The Volkswagen BKR is a 1,984 cc, inline‑four naturally aspirated petrol engine produced between 2005 and 2008. It features gasoline direct injection (FSI), dual overhead camshafts (DOHC), and variable valve timing on the intake cam. This engine was designed for smooth, refined power delivery in premium compact models, producing 110 kW (150 PS) and 200 Nm of torque.

Fitted primarily to the Golf Mk5 GT and Jetta (A5), the BKR was engineered for responsive throttle response and fuel-efficient cruising. Emissions compliance was achieved through precise FSI metering and catalytic conversion, meeting Euro 4 standards for its entire production period.

One documented characteristic is potential intake valve carbon buildup, a known trait of early FSI engines without port injection. This phenomenon, referenced in Volkswagen Group Service Technical Information, occurs because fuel is injected directly into the combustion chamber, bypassing the intake ports. Later engine generations incorporated port injection to mitigate this.

Compliance Note:

Production years 2005–2008 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5680).

BKR Technical Specifications

The Volkswagen BKR is a 1,984 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and sedans (2005-2008). It combines gasoline direct injection (FSI) with variable intake timing to deliver smooth, linear power and good fuel efficiency. Designed to meet Euro 4 standards, it offers a refined and economical driving experience for its vehicle class.

Practical Implications

The FSI system provides smooth, linear power but requires periodic intake valve cleaning due to carbon accumulation inherent in direct injection designs. Using high-quality fuel and adhering to the 15,000 km service interval helps maintain injector performance. The timing chain is generally robust but should be inspected if unusual noises arise. For optimal longevity, use only VW 502 00 or 504 00 specification oil.

Data Verification Notes

Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). LongLife service intervals depend on 504 00 oil.

Emissions: Euro 4 certification applies to all 2005–2008 BKR engines (VCA Type Approval #VCA/EMS/5680).

Power Ratings: Measured under DIN 70020 standards (Volkswagen Group PT‑2008).

Identification Guidance

Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the timing chain cover (Volkswagen SSP 823). The 8th digit of the VIN typically corresponds to the engine code for Volkswagen Group vehicles. Visually, the BKR can be identified by its plastic intake manifold and the "2.0 FSI" badge on the engine cover. It is distinct from turbocharged FSI engines like the BJM.

Engine Family:

The BKR is part of the EA113 engine family. It shares core architecture with other 2.0L FSI engines like the AXW and BKF, but has specific ECU mapping and ancillary components.

Part Interchange:

While some internal components may interchange with other EA113 engines, critical parts like the ECU, injectors, and intake manifold are specific to the BKR application and power output.

Common Reliability Issues - VOLKSWAGEN BKR

The BKR's primary maintenance consideration is intake valve carbon buildup, inherent to its FSI design. While not a catastrophic failure, it can lead to performance issues if neglected. UK DVSA data shows this is a common cause for rough running complaints in high-mileage examples. Regular highway driving and periodic cleaning are recommended mitigation strategies.

Intake valve carbon buildup
Symptoms: Rough idle, hesitation under acceleration, reduced power, increased fuel consumption.
Cause: Lack of fuel washing over intake valves due to direct injection design, allowing oil vapors to bake onto hot surfaces.
Fix: Professional intake valve cleaning (walnut blasting or chemical) per manufacturer procedure; consider installing an oil catch can to reduce future buildup.
High-pressure fuel pump (HPFP) failure
Symptoms: Difficulty starting, engine stuttering or cutting out under load, illuminated check engine light.
Cause: Wear or failure of the camshaft-driven high-pressure fuel pump, a critical component in the FSI system.
Fix: Replace the high-pressure fuel pump with the latest OEM-specified unit; inspect camshaft lobe for wear during replacement.
Ignition coil or spark plug failure
Symptoms: Engine misfires, rough running, loss of power, flashing check engine light.
Cause: Normal wear and tear of ignition components, exacerbated by the engine's specific operating characteristics.
Fix: Replace faulty ignition coils and/or spark plugs with OEM-specified parts; use correct torque specifications.
Variable valve timing (VVT) solenoid issues
Symptoms: Rough idle, reduced power, check engine light with camshaft position codes.
Cause: Wear, sticking, or electrical failure of the variable intake cam timing solenoid or its oil control valve.
Fix: Diagnose solenoid function and oil passages; replace solenoid assembly if faulty, per OEM service information.
