The Volkswagen DFEA is a 1,498 cc, inline‑four turbocharged petrol engine produced between 2016 and 2023. It features direct fuel injection (TSI), a single turbocharger with intercooler, and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 250 Nm of torque, engineered for responsive urban performance and efficient motorway cruising.
Fitted to models such as the Mk7.5 Golf, Passat B8, and Tiguan Mk2—including the 1.5 TSI 150 variants—the…
Production years 2016–2018 meet Euro 6b/6c standards; 2019–2023 models comply with Euro 6d-TEMP and Euro 6d .
The Volkswagen DFEA is a 1,498 cc inline‑four turbocharged petrol engine engineered for compact and mid‑size models (2016–2023). It combines direct injection with a single turbocharger, intercooler, and active cylinder management to deliver strong low‑rpm torque and class-leading fuel economy. Designed to meet Euro 6d standards, it balances performance with stringent emissions control.

The Volkswagen DFEA was used across Volkswagen's Mk7.5/B8 platforms with transverse mounting and shared with Škoda and Audi under the MQB architecture. This engine received platform-specific adaptations—revised engine mounts in the Passat and modified exhaust manifolds in the Tiguan—and from 2020 minor ECU updates improved GPF regeneration logic, creating minor software interchange limits. 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 DFEA is generally robust with proper maintenance, though GPF clogging and carbon buildup are common in urban-driven vehicles. Using VW 504 00/507 00 (0W-20) oil, high-quality 95 RON petrol, and ensuring regular highway driving are essential for longevity beyond 200,000 km.
Top issues include GPF clogging from short trips, intake valve carbon buildup, cylinder deactivation (ACT) system faults, and high-pressure fuel pump wear. All are documented in VW service bulletins and technical updates.
The DFEA powered the Golf Mk7.5, Passat B8, Tiguan Mk2, Škoda Superb III, and Audi A3 8Y (all 1.5 TSI/TFSI 150 variants) from 2016–2023. It belongs to the EA211 evo engine family and was used across the VW Group’s MQB platforms.
Aftermarket ECU tuning is common on the DFEA 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.
Excellent. In a Passat 1.5 TSI 150, expect ~6.5 L/100km (city) and ~4.3 L/100km (highway), or ~55 mpg UK combined. Real-world mixed driving typically returns 50–56 mpg (UK) when the GPF and ACT systems are functioning correctly.
Yes. Like all modern VW petrol engines, the DFEA is an interference design. Timing chain failure—though rare due to front-mounted low-wear design—could cause valve-to-piston contact and catastrophic damage.
Volkswagen mandates 0W-20 synthetic oil meeting VW 504 00 / 507 00 specification. This low-viscosity, low-ash oil is critical for GPF protection, ACT system function, and turbo lubrication. Never substitute with non-approved oils.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
