The Volkswagen CAYA is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2012 and 2015. It features a dual overhead camshaft (DOHC) design with 16 valves and direct fuel injection (TSI), delivering outputs around 110 kW (150 PS) and 250 Nm of torque. Its turbocharged layout provides strong low-end torque for responsive urban and highway drivability.
Fitted primarily to the Mk7 Golf and Jetta (A7 platform), the CAYA engine was engineered for accessible performance in compact family vehicles. Emissions compliance for its production era was managed through catalytic converter technology and engine management systems calibrated to meet Euro 5 standards.
One documented service consideration involves potential high-pressure fuel pump (HPFP) failures in early production units, as noted in Volkswagen workshop documentation. Minor revisions were implemented during the production run to address injector calibration for improved cold-start emissions.
Production years 2012–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9877).
The Volkswagen CAYA is a 1,390 cc inline‑four turbocharged petrol engineered for compact hatchbacks and sedans (2012-2015). It combines direct fuel injection with a single turbocharger to deliver strong, accessible torque and efficient performance. Designed to meet Euro 5 emissions standards, it balances spirited driving with everyday fuel economy.

The turbocharged TSI design provides strong, accessible torque ideal for city and highway driving but requires strict adherence to 15,000 km oil change intervals using VW 502 00/504 00 specification oil to prevent carbon buildup and turbocharger wear. Early CAYA units are susceptible to high-pressure fuel pump (HPFP) failure; inspect for rough running or hard starting and consider preventative replacement if symptoms arise per workshop guidelines. Premium (95 RON) petrol is recommended for optimal performance and injector longevity.
Oil Specs: Requires VW 502 00 / 504 00 specification (Volkswagen Owner's Manual 2013). ACEA C3 oils meeting VW approval are acceptable.
Emissions: Euro 5 certification applies to all 2012-2015 models (VCA Type Approval #VCA/EMS/9877).
Power Ratings: Measured under DIN 70020 standards (Volkswagen Group PT-2014). Output figures are net ratings.

The Volkswagen CAYA was used across Volkswagen's A7 platform with transverse mounting. This engine received platform-specific adaptations-integrated engine mounts and exhaust routing for the Golf and Jetta-and minor revisions were implemented in 2013 for emissions calibration. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the rear of the cylinder block, near the transmission bellhousing (Volkswagen Repair Manual 2013). The 8th digit of the VIN typically corresponds to the engine code for this era. Visually, the CAYA engine can be identified by its black plastic intake manifold with integrated turbocharger inlet and direct injection fuel rail. Critical differentiation from the lower-powered CASD engine: CAYA produces 150 PS vs 122 PS for CASD, and has a different ECU calibration. Service parts like the turbocharger or injectors may have different part numbers.
The CAYA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in high-mileage or poorly maintained examples. Internal Volkswagen workshop data indicates a notable failure rate requiring pump replacement, while adherence to correct oil specifications and intervals is critical for preventing carbon-related issues. Neglecting maintenance makes preventative HPFP inspection and carbon cleaning critical.
Analysis derived from Volkswagen technical bulletins (2012-2015) and general repair industry consensus for TSI engines of this era. Repair procedures should follow manufacturer guidelines.
