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 performance across compact and midsize platforms. Emissions compliance was achieved through a combination of precise direct injection, three‑way catalytic converter, and secondary air injection, meeting Euro 5 standards throughout its production run.
One documented concern is high‑pressure fuel pump (HPFP) wear, which can lead to hard starts or limp mode. This issue, highlighted in Volkswagen Service Technical Bulletin 2011‑07, is often linked to insufficient lubricity in low‑quality fuel or extended service intervals. From 2012, revised HPFP components were introduced to improve durability.
All CJMA production years (2008–2015) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
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 TSI direct-injection system delivers crisp throttle response but requires strict adherence to 15,000 km oil change intervals using VW 502/505‑approved 5W‑40 oil to prevent carbon buildup on intake valves and HPFP wear. Fuel must meet EN 228 (95 RON minimum) to ensure injector and pump longevity. The timing chain is designed as maintenance-free but relies on consistent oil quality; any rattling noise should be investigated immediately. Revised HPFP units from 2012 onward (part #06F 127 025 G) offer improved durability per VW STB 2011‑07.
Oil Specs: Requires VW 502 00 / 505 00 specification (Volkswagen TIS Doc. 06K‑1012). Not interchangeable with Longlife‑04 diesel oils.
Emissions: Euro 5 certification applies to all CJMA production years (2008–2015) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Output assumes 95 RON fuel (Volkswagen TIS Doc. 06K‑1030).

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.
Locate the engine code stamped on the front timing cover near the oil filter housing (Volkswagen TIS 06K‑1005). The 4th–6th digits of the engine code on the VIN plate (e.g., 'CJM') confirm family; full code 'CJMA' appears on the build sticker in the service book or spare wheel well. Visual cue: black plastic intake manifold with red 'TSI' badge. Differentiate from CAEB: CJMA uses a single twin-scroll K04 turbo, while CAEB uses a smaller K03. HPFP part numbers also differ—CJMA uses 06F 127 025 series. Always verify with ETKA part lookup before ordering components.
The CJMA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using low-lubricity fuel or extended service intervals. Volkswagen internal data from 2012 indicated a measurable uptick in HPFP-related warranty claims before 80,000 km, while UK DVSA records show no systemic emissions failures. Short-trip driving and infrequent oil changes accelerate carbon buildup and pump wear, making fuel quality and maintenance adherence critical.
Analysis derived from Volkswagen technical bulletins (2010–2015) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
