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.

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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CK is generally robust when maintained properly. Early units (2005–late 2008) had camshaft lobe wear concerns under high-load conditions, but post-update engines are more durable. Using RON 95 fuel and adhering to 15,000 km oil changes with VW 502 00 spec oil significantly improves longevity. The timing chain is maintenance-free and rarely problematic.
Most documented issues are intake cam lobe wear (pre‑2008), VVT solenoid clogging, valve cover oil leaks, and coolant housing cracks. These are covered in VW service bulletins. Unlike TSI engines, the CK has no carbon buildup due to port injection.
The CK powered the Passat B6 (2.0 FSI 150 PS), Eos (2.0 FSI 150 PS), and Tiguan Mk1 (2.0 FSI 150 PS 4Motion) from 2005 to 2010. It was not used in SEAT, Škoda, or Audi under this code—those brands used related but distinct FSI variants like BLR or BPY.
Limited potential. The CK responds modestly to ECU remapping (+8–12 kW), but lacks forced induction. Significant gains require forced induction conversion, which is complex. Most owners retain stock tune for reliability. Always use high-quality oil post-tune.
In a Passat B6, expect ~9.2 L/100km (city) and ~6.1 L/100km (highway), or ~39 mpg UK combined. The Tiguan 4Motion is slightly thirstier at ~10.0 L/100km city. Real-world economy depends on driving style—aggressive use can push consumption above 11.5 L/100km.
Yes. Like all modern VW petrol engines, the CK is an interference design. If the timing chain fails (extremely rare), piston-to-valve contact will cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine use with proper oil maintenance.
Volkswagen specifies SAE 5W‑40 oil meeting VW 502 00 standards. Always use fully synthetic oil approved to this spec and change every 15,000 km or 12 months to protect camshafts, VVT system, and timing components.
