The Volkswagen CAYB – Petrol is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features direct fuel injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC) with variable valve timing. In standard tune it delivered 155 kW (211 PS), providing strong performance with responsive low‑end torque.
Fitted to performance variants of the Mk6 Golf, Passat, and Scirocco, the CAYB – Petrol was engineered for drivers seeking a blend of high output, refinement, and everyday usability. Emissions compliance for Euro 5 markets was achieved through precise fuel metering, exhaust gas recirculation (EGR), and a three‑way catalytic converter.
One documented concern is potential timing chain tensioner wear, which can lead to a rattling noise or, in severe cases, chain jump. This issue, referenced in Volkswagen Service Technical Bulletin 2028673/2, is often linked to extended service intervals or use of incorrect oil viscosity. Revised tensioner components were introduced in later production runs.
Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9103).
The Volkswagen CAYB – Petrol is a 1,984 cc inline‑four turbocharged petrol engineered for performance-oriented compact and mid-size models (2008-2015). It combines direct fuel injection with a single turbocharger to deliver high power output and strong low‑rpm torque. Designed to meet Euro 5 standards, it balances spirited performance with acceptable fuel economy for its class.

The turbocharger provides strong mid-range torque ideal for overtaking but requires strict adherence to 15,000 km oil change intervals using VW 502 00/504 00 specification oil to prevent timing chain tensioner wear and turbo degradation. Premium unleaded (95 RON minimum, 98 RON recommended) is advised for optimal performance and longevity. The timing chain is designed for longevity but inspection is advised if a rattle is heard, particularly on cold start. Post-2012 models may feature revised tensioner components; pre-2012 units should have the tensioner inspected per SIB 2028673/2 if symptoms arise. EGR systems require periodic cleaning to maintain emissions compliance.
Oil Specs: Requires VW 502 00 / 504 00 specification oil (Volkswagen Owner's Manual 2010). LongLife service intervals require 504 00 spec.
Emissions: Euro 5 certification applies to all 2008–2015 CAYB engines (VCA Type Approval #VCA/EMS/9103).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across model range (Volkswagen PT-2010).

The Volkswagen CAYB – Petrol was used across Volkswagen's Mk6 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Passat-and from 2012 some models received minor ECU updates for emissions refinement, creating no significant interchange limits. 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 Workshop Manual 2.0L TSI). The 8th digit of the VIN typically corresponds to the engine code for this generation. Visually, the engine features a plastic intake manifold on top and a turbocharger mounted at the front of the engine. Differentiate from the CAWA engine by power output (CAYB = 211 PS, CAWA = 170 PS) and specific ECU part numbers. Critical parts like the timing chain tensioner and turbocharger are specific to the CAYB code and model year.
The CAYB – Petrol's primary reliability risk is timing chain tensioner wear, with elevated incidence in vehicles exceeding service intervals or using incorrect oil. Volkswagen service data indicates a notable number of failures linked to oil quality and maintenance neglect, while turbocharger issues are less common but documented in high-mileage examples. Adherence to specified oil type and change intervals makes chain longevity highly probable.
Analysis derived from Volkswagen technical bulletins (2008-2015) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
