The Volkswagen CBDC is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2010 and 2015. It features gasoline direct injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC). This iteration delivered 103 kW (140 PS) and 220 Nm of torque, representing a power increase over earlier 1.4 TSI variants through ECU and turbocharger calibration.

Production years 2010–2015 meet Euro 5 standards .
The Volkswagen CBDC is a 1,390 cc inline‑four turbocharged petrol engine engineered for compact performance models (2010-2015). It combines gasoline direct injection (TSI) with a single turbocharger to deliver responsive power and good fuel efficiency. Designed to meet Euro 5 standards, it balances sporty performance with modern emissions control.

The Volkswagen CBDC was used across Volkswagen's Mk6 platform with transverse mounting. This engine received minor ECU and ancillary updates during its lifecycle, but core mechanical compatibility remains high across its applications. 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.
The CBDC's primary reliability consideration is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles subjected to low-quality fuel or extended service intervals. Volkswagen TSB 2033060/5 documents this issue, while preventative maintenance makes adherence to fuel and oil specifications critical.
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 CBDC is generally robust with proper maintenance. Its main concerns are HPFP failure and carbon buildup, both manageable with quality fuel, correct oil, and timely service. The timing chain is durable. Adhering to service intervals is key to longevity.
The most frequent issues are high-pressure fuel pump (HPFP) failures, carbon buildup on intake valves, and ignition coil/spark plug wear. Water pump and thermostat failures are also common but are typical wear items for this generation of VW engines.
The CBDC 1.4 TSI (140 PS) was used in the Volkswagen Golf Mk6 (2010-2013), Scirocco Mk3 (2010-2015), and Jetta Mk6 (2011-2015). It was often found in sportier trims like the Golf GT.
Aftermarket ECU tuning is common on the CBDC 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.
Official combined figures are around 5.9 L/100km (48 mpg UK). Real-world economy varies: expect 6.8-7.8 L/100km (36-41 mpg UK) in mixed driving, with highway figures closer to 5.2 L/100km (54 mpg UK) if driven gently.
Yes. The CBDC is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain is very reliable.
Volkswagen specifies oil meeting VW 502 00 or 504 00 standards, typically SAE 5W-30. Using the correct specification is crucial for engine and turbocharger protection, especially if following extended service intervals.
