The Volkswagen CG is a 1,984 cc, inline‑four naturally aspirated petrol engine produced between 2006 and 2013. It features port fuel injection, dual overhead camshafts (DOHC), and variable intake timing. In standard form it delivers 118 kW (160 PS) and 200 Nm of torque, with smooth power delivery suited for refined cruising and responsive highway performance.
Fitted to models such as the Mk5 Golf GT, Mk6 Golf, and Mk2 Scirocco—including the 2.0 FSI 160 PS variants—the CG w…
Production years 2006–2008 meet Euro 4 standards; 2009–2013 models comply with Euro 5 depending on market .
The Volkswagen CG is a 1,984 cc inline‑four naturally aspirated petrol engineered for compact performance and mid‑size vehicles (2006–2013). It combines port and direct fuel injection (FSI) with variable intake timing to deliver smooth power and refined operation. Designed to meet Euro 4 and Euro 5 emissions standards, it balances performance with urban efficiency.

The Volkswagen CG was used across Volkswagen's Mk5/Mk6 platforms with transverse mounting. This engine received platform-specific adaptations—revised engine mounts in the Scirocco and modified exhaust manifolds in the Golf GT—and from 2009 the facelifted Golf VI models adopted updated ECU calibrations, creating minor interchange limits. 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 CG is generally robust with smooth power delivery. Its main concern is carbon buildup due to FSI direct injection. With proper maintenance—especially using VW 502 00/504 00 oil, timely oil changes, and periodic intake cleaning—the engine can reliably exceed 200,000 km.
Top issues include carbon buildup on intake valves, PCV system failure, high-pressure fuel pump wear, and variable cam adjuster faults. These are documented in Volkswagen service bulletins, particularly SIB 2010‑12‑FSI‑1984 for intake and PCV concerns.
The CG powered the Golf V, Golf VI, Scirocco II, and Passat B6 from 2006–2013. All are 2.0 FSI 160 PS variants under the FSI family, meeting Euro 4 or Euro 5 depending on year.
Aftermarket ECU tuning is common on the CG 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 VI 2.0 FSI 160 PS, real-world consumption is ~8.2 L/100km (city) and ~5.6 L/100km (highway), or about 38 mpg UK combined. With conservative driving, 40–44 mpg UK is achievable on mixed routes. Fuel quality and service history significantly affect results.
Yes. The CG is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is designed as maintenance-free and typically lasts the engine’s lifetime if oil is changed correctly.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Never use older 501 01 oils. Change every 15,000 km or annually to protect high-pressure fuel pump, cam adjusters, and timing components.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
