The Volkswagen CHHB is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2019. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivers 92 kW (125 PS) and 200 Nm of torque, with strong low‑rpm response ideal for urban and motorway driving.
Fitted to models such as the Mk7 Golf, Mk2 Jetta, and Mk3 Touran—including the 1.4 TSI 125 PS variants—the CHHB was engineered for respons…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 depending on market .
The Volkswagen CHHB is a 1,395 cc inline‑four turbocharged petrol engineered for compact and family vehicles (2012–2019). It combines direct injection (TSI) with variable valve timing to deliver responsive low‑end torque and smooth high‑rpm power. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with urban efficiency.

The Volkswagen CHHB was used across Volkswagen's Mk7/Mk2 platforms with transverse mounting and shared with SEAT and Škoda under the MQB architecture. This engine received platform-specific adaptations—revised engine mounts in the Touran and modified exhaust routing in the Golf Variant—and from 2016 the EA211 evo update introduced updated pistons and injectors, creating minor interchange limits. Partnerships enabled SEAT and Škoda to use identical CHHB units in Leon and Octavia. 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 CHHB is generally robust but early models (2012–2015) had oil consumption issues due to piston design. Post-2016 revisions improved durability significantly. With proper maintenance—especially using VW 502 00/504 00 oil and timely changes—the engine can reliably exceed 200,000 km.
Top issues include excessive oil consumption (early units), carbon buildup on intake valves, PCV system failure, and turbo wastegate rattle. These are documented in Volkswagen service bulletins, particularly SIB 2015‑07‑TSI‑1395 for oil use.
The CHHB powered the Golf VII, Jetta Mk2, Touran II, and was also used by SEAT (León Mk3) and Škoda (Octavia III) from 2012–2019. All are 1.4 TSI 125 PS variants under the EA211 family, meeting Euro 5 or Euro 6 depending on year.
Aftermarket ECU tuning is common on the CHHB 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 VII 1.4 TSI 125 PS, real-world consumption is ~6.5 L/100km (city) and ~4.8 L/100km (highway), or about 48 mpg UK combined. With conservative driving, 50–55 mpg UK is achievable on mixed routes. Fuel quality and service history significantly affect results.
Yes. The CHHB 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‑30 or 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 pistons, turbo, and timing components.
