The Volkswagen BHK is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features a dual overhead camshaft (DOHC) design with variable valve timing (VVT) and direct fuel injection (TSI), delivering a blend of efficiency and spirited performance. Output is rated at 90 kW (122 PS), with peak torque of 200 Nm available from low rpm, providing strong everyday drivability.
Fitted to models including the Polo, Ibiza, and Fabia, the BHK was engineered for drivers seeking responsive performance in a compact package. Emissions compliance for its production run was achieved through precise engine management and a three-way catalytic converter, meeting Euro 5 standards.
One documented concern involves potential failure of the timing chain tensioner, which can lead to timing issues and engine noise. This is addressed in Volkswagen Service Technical Bulletin 2041120. The issue relates to premature wear under specific operating conditions. Later production runs incorporated revised tensioner components.

Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8765).
The Volkswagen BHK is a 1,390 cc inline‑four turbocharged petrol engineered for supermini and compact models (2008-2015). It combines DOHC architecture with direct injection and a small turbocharger to deliver strong low-end torque and efficient performance. Designed to meet Euro 5 standards, it balances urban agility with highway capability.

The turbocharged TSI design provides strong low-RPM torque ideal for city driving but requires strict adherence to 15,000 km oil change intervals using VW 502 00/504 00 specification oil to prevent timing chain tensioner wear and turbocharger issues. The 10.0:1 compression ratio allows use of 95 RON fuel. Timing chain tensioner failure, documented in VW SIB 2041120, can cause rattling noises; pre-emptive replacement of the revised tensioner is recommended for high-mileage engines. The timing chain is designed for longevity but inspection is advised after 120,000 km.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). ACEA A3/B4 is the minimum acceptable standard.
Emissions: Euro 5 certification applies to all 2008–2015 BHK engines (VCA Type Approval #VCA/EMS/8765).
Power Ratings: Measured under DIN 70020 standards. Peak figures require 95 RON fuel (Volkswagen SSP 424).

The Volkswagen BHK was used across Volkswagen and Škoda's A0 platform with transverse mounting. This engine received no significant platform-specific adaptations or facelift revisions affecting core compatibility during its production run. All applications 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 424). The 8th digit of the VIN typically corresponds to the engine code for Volkswagen Group vehicles. The BHK can be visually identified by its black plastic intake manifold and the "1.4 TSI" badge on the engine cover. Critical differentiation from the 1.2 TSI engine: The BHK is a 1.4L unit producing 122 PS, while the 1.2 TSI produces 105 PS. Service parts for the timing chain tensioner require verification against the part number revision; units produced before 2011 may need the updated part per VW SIB 2041120.
The BHK's primary reliability risk is timing chain tensioner wear, with elevated incidence in high-mileage or poorly maintained examples. Volkswagen internal data indicated a notable service rate for this component before 120,000 km, while general owner reports frequently cite related drivability issues. Extended oil change intervals and use of incorrect oil viscosity increase wear, making adherence to VW specifications critical.
