The Volkswagen DFEB is a 1,498 cc, inline‑four turbocharged petrol engine produced between 2020 and 2024. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing with Miller — cycle operation. In standard form it delivered 110 kW (150 PS) and 250 Nm of torque, optimized for low fuel consumption and responsive urban performance.
Fitted to models such as the Mk8 Golf, T — Roc, and Taigo—including the Golf 1.5 TSI EVO2 and T — Roc 1.5 TS…
All production years (2020–2024) meet Euro 6d standards .
The Volkswagen DFEB is a 1,498 cc inline‑four turbocharged petrol engineered for compact and crossover models (2020–2024). It combines direct fuel injection (TSI) with a single turbocharger and Miller-cycle valve timing to deliver responsive mid‑range torque and class-leading fuel efficiency. Designed to meet Euro 6d emissions standards, it balances performance with ultra-low particulate emissions.

The Volkswagen DFEB was used across Volkswagen's Mk8 and MQB A0 platforms with transverse mounting. This engine received platform-specific adaptations—enhanced thermal management in the Golf Mk8 and revised intake routing in the Taigo—and from 2022 all variants adopted updated camshaft metallurgy per service bulletin, creating minor service part interchange limits. The DFEB is exclusive to Volkswagen and not shared with Škoda or SEAT in this configuration. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DFEB offers excellent efficiency and refined performance, but pre-2022 models are prone to HPFP cam lobe wear. Post-2022 revisions improved durability. With correct oil (VW 508 00/509 00), regular highway driving for GPF regeneration, and conservative use, it can be dependable beyond 200,000 km.
Top issues include HPFP cam lobe wear, GPF clogging due to short trips, intake valve carbon buildup, and PCV valve failure in the rocker cover. These are documented in Volkswagen service bulletin 2021‑05‑TSI.
The DFEB appears in the Golf Mk8, T-Roc, Taigo, and ID.7 range extender (2023–2024) as the 1.5 TSI EVO2 150 PS. It’s part of the EA211 EVO2 family and is exclusive to Volkswagen in this configuration.
Aftermarket ECU tuning is common on the DFEB 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.
In a Golf 1.5 TSI EVO2 150 PS, expect ~5.8 L/100km (city) and ~4.0 L/100km (highway), or about 54 mpg UK combined. Real-world mixed driving typically returns 50–57 mpg (UK) with conservative use.
Yes. The DFEB is an interference engine. Timing chain failure—though rare—can cause piston-to-valve contact and catastrophic damage. However, the front-mounted chain is robust with proper oil maintenance.
Volkswagen specifies SAE 0W‑20 oil meeting VW 508 00 or 509 00 standards. Using non-approved oil risks HPFP and camshaft wear. Change every 15,000 km or annually.
