The Volkswagen CLJA 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, delivering 147 kW (200 PS) and 280 Nm of torque. Its turbocharged direct injection system enables strong low‑rpm torque for responsive everyday drivability.
Fitted to models such as the Mk5 and Mk6 Golf R, Scirocco R, and Audi S3 (8P), the CLJA was engineered for high p…
All production years 2008–2015 meet Euro 5 standards .
The Volkswagen CLJA is a 1,984 cc inline‑four turbocharged petrol engine engineered for performance hatchbacks and coupés (2008–2015). It combines gasoline direct injection (TSI) with a single turbocharger to deliver strong mid‑range pull and high‑rev responsiveness. Designed to meet Euro 5 emissions standards, it balances sporty performance with acceptable fuel economy.

The Volkswagen CLJA was used across Volkswagen's Mk5/Mk6 platforms with transverse mounting and shared with Audi under the Volkswagen Group modular strategy. This engine received platform-specific adaptations—reinforced mounts in the Golf R and revised cooling in the Scirocco R—and from 2011 minor HPFP updates were implemented, creating service part distinctions. 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CLJA is robust when maintained properly. Early units (2008–2011) had HPFP issues, but post-2011 revisions improved durability. Using RON 98 fuel, VW 502 00 oil, and adhering to service intervals greatly enhances longevity. Many examples exceed 200,000 km with no major failures.
The top issues are HPFP cam follower wear, turbo oil seal leaks, and minor carbon buildup on intake valves. Timing chain problems are rare. HPFP failure is well-documented in Volkswagen STB 2010‑07 and is the most frequent major repair.
The CLJA powered the Golf R Mk5 (2008–2009), Golf R Mk6 (2009–2013), Scirocco R (2009–2015), and select Audi S3 (8P) models in Europe. All are transverse-mounted 2.0 TSI performance variants with 200 PS output.
Aftermarket ECU tuning is common on the CLJA 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.
Real-world consumption is ~9.5 L/100km (city) and ~6.2 L/100km (highway), or ~30 mpg UK combined. Aggressive driving pushes this to 11–12 L/100km. Using RON 98 and smooth driving can improve economy slightly.
Yes. The CLJA is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, chain failures are extremely rare; the system is generally durable with proper oil maintenance.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 (petrol) or 505 00 (petrol/diesel) standards. Do not use Longlife (504/507) oils. Change every 15,000 km or annually to protect the turbo and HPFP system.
