The Volkswagen CBDA is a 1,390 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). This engine was part of VW's effort to downsize while maintaining performance, delivering outputs around 90 kW (122 PS) and 200 Nm of torque, providing strong low-rpm pull for everyday drivability.
Fitted to models such as the Mk5 and Mk6 Golf, Jetta, and Scirocco, the CBDA was engineered for responsive performance and improved fuel efficiency. Emissions compliance was achieved through precise direct injection and exhaust after-treatment, allowing it to meet Euro 5 standards across its production run.
One documented concern is potential high-pressure fuel pump (HPFP) failure, which can lead to sudden loss of power or no-start conditions. This issue, referenced in Volkswagen Technical Service Bulletin 2033065/5, is often linked to fuel quality or lubrication issues within the pump's internal components. Later production runs incorporated revised pump designs.
Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CBDA is a 1,390 cc inline‑four turbocharged petrol engineered for compact hatchbacks and sedans (2008-2015). It combines direct fuel injection (TSI) with a single turbocharger to deliver responsive acceleration and improved fuel efficiency. Designed to meet Euro 5 standards, it balances sporty performance with everyday economy.

The turbocharged TSI design offers strong low-end torque ideal for city driving but demands high-quality fuel (95 RON minimum) and strict adherence to 15,000 km oil change intervals using VW-spec oil to prevent carbon buildup and HPFP failure. The timing chain is generally robust but requires monitoring for tensioner noise. Intake valves are prone to carbon deposits due to direct injection; periodic cleaning is recommended. The HPFP, referenced in TSB 2033065/5, should be inspected if drivability issues arise.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). ACEA A3/B4 is the underlying standard.
Emissions: Euro 5 certification applies to all CBDA production years (2008-2015) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across model range (Volkswagen SSP 473).

The Volkswagen CBDA was used across Volkswagen's A5 platform with transverse mounting. This engine received platform-specific adaptations-standardised ECU mapping for Golf/Jetta and revised intake manifolds for Scirocco-and no major facelift revisions affecting core compatibility occurred during its production. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, just below the fuel injectors on the intake side (Volkswagen SSP 473). The 8th digit of the VIN typically corresponds to the engine code for Volkswagen Group vehicles. Visually, the CBDA features a plastic intake manifold with 'TSI' branding and a single intercooler pipe running to the turbo. Differentiate from the CAVE engine (same displacement, 160 PS) by checking the power output label in the service book or via VCDS; CAVE has a larger turbo and different ECU mapping. Engine mounts and ancillaries are generally consistent across compatible models.
The CBDA'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 service data indicates a notable number of replacements under warranty, while owner reports frequently cite drivability issues preceding failure. Fuel quality and maintenance adherence make preventative measures critical.
Analysis derived from Volkswagen technical bulletins (2008-2015) and aggregated owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
