The Volkswagen CJMA is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivers 147 kW (200 PS) and 280 Nm of torque, with strong mid‑range response and refined high‑rpm character.
Fitted to models such as the Golf Mk6 GTI, Scirocco, Passat B6/B7, and Tiguan, the CJMA was engineered for sporty yet efficient performanc…
All CJMA production years (2008–2015) meet Euro 5 emissions standards .
The Volkswagen CJMA is a 1,984 cc inline‑four turbocharged petrol engine engineered for sporty compact and midsize models (2008–2015). It combines direct fuel injection (TSI) with a single turbocharger to deliver strong mid‑range torque and high‑rev responsiveness. Designed to meet Euro 5 standards, it balances performance with regulatory compliance and everyday drivability.

The Volkswagen CJMA was used across Volkswagen's Mk6/B6/B7 platforms with transverse mounting and shared with Škoda and SEAT under the VW Group modular strategy. This engine received platform-specific adaptations—reinforced mounts in the Tiguan and revised cooling in the Scirocco—and from 2012 the Golf GTI Mk6 facelift retained the CJMA while other models transitioned to EA888 Gen 3. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CJMA offers strong performance and refinement, but early units (2008–2011) are prone to HPFP failures if maintenance is neglected. Later revisions improved pump durability. With proper care—quality 95 RON fuel, 15K km oil changes using VW 502/505 oil, and regular carbon cleaning—it can be very dependable beyond 200,000 km.
Top issues include high-pressure fuel pump wear, intake valve carbon buildup (due to direct injection), turbo actuator faults, and plastic coolant flange leaks. HPFP concerns are well-documented in VW STB 2011‑07, while carbon buildup is a known trait of all TSI direct-injection engines.
The CJMA powered the Golf Mk6 GTI (2009–2013), Scirocco (2008–2015), Passat B6/B7 (2008–2014), and Tiguan (2008–2015). It was also used in Škoda Superb II and SEAT Exeo under VW Group platform sharing. All applications are 200 PS variants of the 2.0 TSI.
Aftermarket ECU tuning is common on the CJMA 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.
In a Golf GTI Mk6, expect ~9.5 L/100km (city), ~6.2 L/100km (highway), or ~35 mpg UK combined. Real-world mixed driving typically yields 30–38 mpg UK. Economy varies by model—Tiguan and Passat are slightly thirstier due to weight and gearing.
Yes. The CJMA is an interference engine. If the timing chain fails (rare but possible under oil starvation), pistons will contact open valves, causing catastrophic internal damage. Prompt attention to any timing-related noises is essential.
Volkswagen specifies SAE 5W‑40 synthetic oil meeting VW 502 00 (petrol) or 505 00 (diesel-compatible) standards. Never use non-approved oils. Change every 15,000 km or annually to protect the HPFP, turbo, and timing chain.
