The Volkswagen DNUC is a 1,968 cc, inline‑four turbo‑diesel engine produced between 2015 and 2020. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 340 Nm of torque, engineered for responsive low‑rpm performance and compliance with Euro 6 emissions.
Fitted to models such as the Golf Mk7, Passat B8, and Tiguan Mk2—including the 2.0 TDI 150 variants—the DN…
All DNUC engines (2015–2020) meet Euro 6b standards .
The Volkswagen DNUC is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2015–2020). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and refined cruising. Designed to meet Euro 6b emissions standards, it balances performance with fuel efficiency and regulatory compliance.

The Volkswagen DNUC was used across Volkswagen's MQB platforms with transverse mounting and shared with Škoda and SEAT under the VAG group. This engine received platform-specific adaptations—revised engine mounts in the Tiguan and modified exhaust routing in the Passat—and from 2018 the facelifted Golf Mk7.5 retained the same engine code but with updated HPFP hardware, creating minor service part distinctions. Partnerships enabled Škoda Octavia and SEAT Ateca to use identical DNUC 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DNUC is generally robust when maintained correctly. Early units (pre-2018) have a known HPFP wear issue, but post-revision engines are more durable. Using EN 590 diesel and VW 507 00 oil at 15,000 km intervals greatly improves longevity. The timing chain is front-mounted and low-risk compared to older VW diesels.
Main issues include HPFP wear (especially pre-2018), AdBlue system warnings, EGR cooler leaks, and turbo actuator calibration drift. These are documented in Volkswagen service bulletins. Emissions hardware is otherwise reliable if driven with occasional highway use to enable full DPF regeneration.
The DNUC powered the Golf Mk7 (2015–2020), Passat B8 (2015–2020), and Tiguan Mk2 (2016–2020) as the 2.0 TDI 150. It was also used in Škoda Octavia Mk3 and SEAT Ateca under VAG group sharing. All meet Euro 6b and include AdBlue/SCR systems.
Aftermarket ECU tuning is common on the DNUC 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 Golf 2.0 TDI 150, expect ~5.0 L/100km (city) and ~3.8 L/100km (highway), or ~56 mpg UK combined. Real-world mixed driving typically returns 50–60 mpg UK. Economy depends on AdBlue system health and driving style—short trips reduce efficiency due to frequent regenerations.
Yes. Like all modern VW engines, the DNUC is an interference design. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain has low failure rates with proper oil maintenance.
Volkswagen mandates VW 507 00 (5W-30) low-ash synthetic oil. This is critical for DPF and HPFP protection. Never substitute with 504 00 or generic ACEA C3 oils. Change every 15,000 km or 12 months, whichever comes first.
