The Volkswagen CGGB is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2018. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 110 kW (150 PS) and 250 Nm of torque. Its compact design and high low — end torque made it a responsive and efficient option in VW’s compact and mid — size lineup.
Fitted to models including the Mk7 Golf, Passat B8, and Škoda Octavia III, the CGGB was engineered f…
All production years 2012–2018 meet Euro 6 standards .
The Volkswagen CGGB is a 1,395 cc inline‑four turbocharged petrol engine engineered for compact and mid-size hatchbacks/sedans (2012–2018). It combines direct injection (TSI) with a small single turbocharger to deliver strong low-end torque and efficient cruising. Designed to meet Euro 6 emissions standards, it balances responsive performance with regulatory compliance.

The Volkswagen CGGB was used across Volkswagen's Mk7 and B8 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific calibrations—revised cooling in the Golf and modified mounts in the Passat—and from late 2015 the timing tensioner was updated, creating minor service part distinctions. Partnerships enabled Škoda and SEAT to use identical long blocks. 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 CGGB is generally reliable when maintained properly, but early models (2012–2015) are prone to timing chain tensioner wear. Post-late-2015 revisions improved durability. Using correct oil (VW 502 00/504 00), avoiding frequent short trips, and timely servicing greatly extend engine life.
Top issues include timing chain tensioner wear, turbo wastegate sticking, PCV valve failure in the cam cover, and high-pressure fuel pump degradation. All are documented in VW service bulletins, especially STB 2014‑12.
The CGGB powered the Golf Mk7 (2012–2018), Passat B8 (2014–2018), and was shared with Škoda Octavia III (2013–2018) and SEAT Leon 5F (2013–2018). It was never used in Polo or Tiguan—those used other EA211 variants.
Aftermarket ECU tuning is common on the CGGB 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 ~7.5 L/100km (city) and ~5.0 L/100km (highway), or ~45 mpg UK combined. Official NEDC figures quoted ~5.4 L/100km. Aggressive driving easily exceeds 9.0 L/100km.
Yes. The CGGB is an interference engine. Timing chain failure—though rare—can cause piston-to-valve contact and catastrophic damage. However, the chain is generally durable if oil is changed regularly and short-trip driving is minimized.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Never use 507 00 (diesel) oil. Change every 10,000 km or 12 months to protect the turbo, HPFP, and timing components.
