The Volkswagen T Petrol 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). In standard form it delivered 90 kW (122 PS), with higher — output versions reaching 118 kW (160 PS) and torque figures between 200–240 Nm.

Production years 2008–2015 meet Euro 5 standards .
The Volkswagen T Petrol is a 1,390 cc inline‑four turbocharged petrol engineered for compact and light commercial vehicles (2008–2015). It combines gasoline direct injection with a single turbocharger to deliver responsive low-end torque and brisk acceleration. Designed to meet Euro 5 emissions standards, it balances performance with urban efficiency.

The Volkswagen T Petrol was used across Volkswagen's Mk5/Mk6 platforms with transverse mounting and shared with Škoda and SEAT under the MQB precursor strategy. This engine received platform-specific adaptations—reinforced mounts in the T5 Transporter and revised cooling in the Golf—and from 2012 the facelifted Jetta adopted updated HPFP internals, creating minor interchange limits. Partnerships enabled Škoda’s Octavia and SEAT’s Leon to use identical TSI units. 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 T Petrol offers strong performance and efficiency, but early models (2008–2011) had HPFP reliability concerns. Later revisions (post-2012) improved pump durability, so well-maintained examples can be robust. Regular servicing and using VW 502 00/504 00 oil greatly aid longevity.
The biggest issues are high-pressure fuel pump wear, intake valve carbon buildup (due to direct injection), turbo oil seal leaks, and plastic coolant housing failures. These are well-documented in Volkswagen service bulletins and technical campaigns.
This 1.4L TSI was used in the Golf Mk6, Jetta Mk5, T5 Transporter, as well as Škoda Octavia Mk2 and SEAT Leon Mk2 from 2008–2015. Output ranged from 122 PS to 160 PS depending on application and model year.
Aftermarket ECU tuning is common on the T 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.
Good for a turbo petrol. In a Golf 1.4 TSI (122 PS), expect ~7.2 L/100km (city) and ~5.1 L/100km (highway), or about 40 mpg UK combined. Real-world figures vary by driving style, but 35–45 mpg (UK) is typical on mixed roads.
Yes. Like most modern VW engines, the T Petrol is an interference design. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is generally durable with proper maintenance.
Volkswagen specifies synthetic oil meeting VW 502 00 or 504 00 standards (typically 5W‑30 or 5W‑40). Always use a quality oil designed for turbocharged direct-injection engines and change it every 10,000–15,000 km.
