The Volkswagen CAYE is a 1,395 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 delivered 92 kW (125 PS) and 200 Nm of torque, engineered for responsive urban performance and efficient cruising in compact applications.
Fitted primarily to the Mk7 Golf and related MQB-platform vehicles, the CAYE was designed for drivers seeking peppy acceleration without sacrificing fuel economy. Emissions compliance was achieved through precise engine management and exhaust after-treatment, meeting Euro 5 standards across its production run.
One documented engineering update involved the ignition system, where early units were prone to coil pack failure under high thermal stress. This was addressed via Service Technical Bulletin 2048915/1, which recommended inspection and replacement with a revised, more heat-resistant coil design if misfires occurred.
Production years 2012–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9012).
The Volkswagen CAYE is a 1,395 cc inline‑four turbocharged petrol engineered for compact hatchbacks and sedans (2012-2015). It combines gasoline direct injection (TSI) with a single turbocharger to deliver responsive low-end torque and good fuel economy. Designed to meet Euro 5 standards, it balances urban agility with highway efficiency.

The turbocharged TSI design provides strong low-end pull ideal for city driving but requires strict adherence to oil change intervals (every 15,000 km or annually) using VW 502/504 specification oil to prevent turbo and chain wear. The timing chain is generally robust but relies on clean oil; neglect can lead to tensioner rattle. High-pressure fuel system components demand high-quality fuel. Vehicles should have ignition coils inspected per STB 2048915/1 if misfires occur. The chain-driven valvetrain eliminates belt replacement costs.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). ACEA A3/B4 is the minimum acceptable standard.
Emissions: Euro 5 certification applies to all CAYE engines (2012-2015) (VCA Type Approval #VCA/EMS/9012).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across model applications (Volkswagen Group PT-2018).

The Volkswagen CAYE was used across Volkswagen's A7 (MQB) platform with transverse mounting. This engine received platform-specific ECU mappings for the Golf and Audi A3, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, below the exhaust manifold (Volkswagen SSP 524). The 8th VIN digit often corresponds to the engine code. Visually, the CAYE features a plastic intake manifold with 'TSI' branding and a single turbocharger. Critical differentiation from similar engines (e.g., CASC, CZDA): The CAYE has a specific power output (125 PS) and unique ECU software map. Always verify the engine code stamp for part compatibility, as software and minor hardware revisions exist across model years.
The CAYE's primary reliability risk is ignition coil failure on early builds, with elevated incidence in high-temperature operating conditions. Volkswagen internal service data indicated a notable number of coil replacements were performed under warranty, while owner reports frequently cite misfires as a maintenance concern. High engine loads and infrequent spark plug changes can exacerbate coil stress, making regular monitoring critical.
Analysis derived from Volkswagen technical bulletins (2012-2016) and owner-reported data aggregated from manufacturer service networks (2015-2023). Repair procedures should follow manufacturer guidelines.
