The Volkswagen CAVB is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2012 and 2015. It features direct fuel injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC). This engine was designed to offer a balance of performance and efficiency for Volkswagen's compact models, delivering responsive power for everyday driving.
Fitted primarily to the Mk7 Golf and related MQB-platform vehicles like the Audi A3 (8V), the CAVB was engineered for drivers seeking brisk acceleration and refined operation. Emissions compliance was achieved through technologies like variable valve timing, allowing it to meet stringent Euro 5 standards.
One documented concern involves potential high-pressure fuel pump (HPFP) failure, noted in Volkswagen Group Service Bulletin TSB 2043078/1. This issue can be linked to fuel quality or extended service intervals. Volkswagen addressed this through updated pump designs and revised maintenance schedules in subsequent model years.
Production years 2012–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5680).
The Volkswagen CAVB is a 1,390 cc inline‑four turbocharged petrol engine engineered for compact hatchbacks and sedans (2012-2015). It combines direct fuel injection (TSI) with a single turbocharger to deliver responsive performance and good fuel efficiency. Designed to meet Euro 5 standards, it balances sporty character with everyday practicality.

The turbocharged TSI design provides strong mid-range torque ideal for overtaking but requires strict adherence to 15,000 km or annual oil change intervals using VW 504 00 specification oil to protect the turbo and high-pressure fuel system. Extended oil service can accelerate wear on the timing chain tensioner and HPFP. The engine demands high-quality 95 RON (EU) petrol to prevent pre-ignition and maintain performance. HPFP failures, while not universal, are a known risk; using premium fuel and proactive replacement per TSB 2043078/1 can mitigate this. The chain-driven timing system is designed to last the engine's life but relies on clean oil for lubrication.
Oil Specs: Requires VW 502 00 / 504 00 specification (Volkswagen Owner's Manual). 504 00 is preferred for extended intervals.
Emissions: Euro 5 certification applies to all CAVB production years (VCA Type Approval #VCA/EMS/5680).
Power Ratings: Measured under DIN 70020 standards. Output requires 95 RON fuel (Volkswagen SSP 507).

The Volkswagen CAVB was used across Volkswagen Group's MQB platform with transverse mounting. This engine received platform-specific adaptations-shared ECU calibrations with the Audi A3 and identical mounting points in the SEAT León-creating broad parts compatibility within the group. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the timing chain cover (Volkswagen SSP 507). The 8th digit of the VIN typically corresponds to the engine code for Group vehicles. Visually, the CAVB can be identified by its plastic intake manifold and the '1.4 TSI' badge on the engine cover. Critical differentiation from the higher-powered 150 PS variant (CAAD) is the engine code stamp and ECU software; parts like the turbocharger and injectors are often interchangeable but require matching ECU maps. Always verify the engine code before ordering parts.
The CAVB's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using lower-grade fuel or exceeding service intervals. Internal Volkswagen data indicated a measurable failure rate before 100,000 km in non-compliant cases, while owner reports frequently cite fuel quality as a factor. Extended oil change intervals and use of substandard petrol make adherence to OEM maintenance and fuel specifications critical.
