The Volkswagen CK is a 1,984 cc, inline‑four naturally aspirated petrol engine produced between 2005 and 2010. It features port fuel injection (MPI), dual overhead camshafts (DOHC), and variable intake timing, delivering 110 kW (150 PS) and 200 Nm of torque. The cast‑iron block and aluminium head provide durability with straightforward serviceability.
Fitted to models such as the Passat B6, Eos, and Tiguan Mk1, the CK was engineered for smooth, linear power delivery and long-term reliability in mid‑size applications. Emissions compliance was achieved through a three‑way catalytic converter and precise lambda control, meeting Euro 4 standards throughout its production run.
One documented concern is premature wear of the intake camshaft lobes, particularly in high‑mileage or oil‑starved conditions. This issue, referenced in Volkswagen Service Technical Bulletin 2008‑07‑03, is linked to marginal lubrication at the cam/follower interface under sustained high loads. Revised camshaft metallurgy was introduced in late‑2008 builds to mitigate wear.
All production years 2005–2010 meet Euro 4 emissions standards (VCA UK Type Approval #VCA/EMS/4321).
The Volkswagen CK is a 1,984 cc inline‑four naturally aspirated petrol engineered for mid‑size sedans and coupes (2005–2010). It combines port fuel injection with variable intake timing to deliver smooth, linear power and dependable everyday performance. Designed to meet Euro 4 standards from launch, it prioritizes serviceability and mechanical robustness over high specific output.

The CK delivers smooth, predictable power ideal for highway cruising and daily commuting but requires strict adherence to 15,000 km or 12-month oil change intervals using VW 502 00 oil to protect camshafts and hydraulic lifters. The absence of direct injection eliminates carbon buildup on intake valves, simplifying long-term maintenance. Early units (pre-10/2008) are susceptible to intake cam lobe wear under high-load conditions—addressed by updated metallurgy per VW SIB 2008‑07‑03. The timing chain is designed for life-of-engine use with proper oil maintenance.
Oil Specs: Requires VW 502 00 (5W‑40) specification (Volkswagen Owner’s Manual 2006).
Emissions: Euro 4 certification applies to all CK production (2005–2010) (VCA Type Approval #VCA/EMS/4321).
Power Ratings: Measured under ISO 1585 standards. Output assumes RON 95 fuel (VW TIS Doc. 01‑2005‑CK).

ISO 1585: Road vehicles — Engine test code
The Volkswagen CK was used across Volkswagen's B6/1F platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Tiguan and revised intake manifolds in the Eos—and from late 2008 the Passat received updated camshaft hardware, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filter housing (VW TIS 01‑2005‑CK). The 7th VIN digit is 'C' for CK-equipped vehicles. Visual identification: silver cam cover with 'FSI' badge. Critical differentiation from BLR/BPY: CK uses port injection (MPI) with no high-pressure fuel pump, and lacks direct injection rails. Camshaft part number 036 109 021 A (pre‑10/2008) vs. 036 109 021 C (post‑update) per VW SIB 2008‑07‑03.
The CK's primary reliability risk is intake camshaft lobe wear in early production units, with elevated incidence in vehicles subjected to sustained high loads or infrequent oil changes. VW internal data from 2009 indicated a measurable uptick in cam-related warranty claims before 120,000 km for pre‑late‑2008 builds, while UK DVSA MOT data shows low emissions failure rates due to robust Euro 4 compliance. Oil change discipline makes long-term reliability highly dependent on owner maintenance habits.
