The Volkswagen CBZB is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 155 kW (211 PS) and 280 Nm of torque. Its turbocharged direct injection system enables strong low‑rpm torque for responsive everyday drivability.
Fitted to models such as the Mk5 and Mk6 Golf R, Scirocco R, and Audi S3 (8P), the CBZB was engineered for high p…
All production years 2008–2015 meet Euro 5 standards .
The Volkswagen CBZB is a 1,984 cc inline‑four turbocharged petrol engineered for high‑performance hatchbacks and coupes (2008–2015). It combines direct fuel injection (TSI) with a single turbocharger to deliver strong low‑rpm torque and high‑rev responsiveness. Designed to meet Euro 5 emissions standards, it balances track‑capable output with daily usability.

The Volkswagen CBZB was used across Volkswagen's Mk5/Mk6 platforms with longitudinal mounting and shared with Audi for transverse applications in performance models. This engine received platform-specific adaptations-reinforced mounts in the Golf R and revised intercooler routing in the Scirocco R-and from 2011 the Audi S3 received HPFP updates, creating minor interchange limits. Partnerships enabled Audi's 2.0 TFSI to share core architecture. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CBZB is generally robust when maintained properly. Early units (2008–2011) had HPFP concerns, but post-2011 revisions improved durability. Regular oil changes with VW 502 00/505 00 oil and use of 98 RON fuel greatly enhance longevity. Many examples exceed 200,000 km with no major issues.
Top issues include HPFP wear (especially pre-2011), intake valve carbon buildup due to direct injection, K04 turbo actuator faults, and PCV system leaks. These are documented in Volkswagen SIB 2012‑07 and TIS service notes.
The CBZB powered the Mk5 Golf R (2009–2013), Scirocco R (2009–2017), and Audi S3 (8P, 2008–2012). It was exclusive to high-performance TSI/TFSI variants and not used in standard GTI or TDI models.
Aftermarket ECU tuning is common on the CBZB platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Real-world consumption is ~9.5 L/100km (city) and ~6.2 L/100km (highway), or about 30 mpg UK combined. Aggressive driving reduces economy significantly; conservative use can achieve mid-30s mpg UK.
Yes. The CBZB is an interference engine. If the timing chain fails (rare but possible with severe oil neglect), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is highly durable with proper maintenance.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 (petrol) or 505 00 (diesel-compatible) standards. Always use this specification and change every 10,000–15,000 km to protect the turbo, HPFP, and timing system.
