The Volkswagen DLUB 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), dual overhead camshafts (DOHC), and a dual-loop exhaust gas recirculation system. In standard form it delivers 110 kW (150 PS) and 340 Nm of torque, with strong low‑rpm pull for responsive everyday driving.
Fitted to models such as the Mk7 Golf, Mk2 Tiguan, and Passat B8—including the 2.0 TDI 150 variants—the DLUB was engineered for refined efficiency and relaxed motorway cruising. Emissions compliance was achieved through a high-pressure EGR loop, low-pressure EGR loop, diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue, meeting Euro 6 standards from launch.
One documented concern is excessive oil consumption in early production units, highlighted in Volkswagen Service Technical Bulletin 2017‑08. This is attributed to piston ring land design tolerances allowing oil migration into the combustion chamber. From mid‑2017, revised pistons and rings were introduced to address the issue.
All DLUB production years (2015–2020) meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen DLUB is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2015–2020). It combines Bosch CRS3 common‑rail injection with a BorgWarner variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient highway cruising. Designed to meet Euro 6 standards from launch, it integrates dual-loop EGR and SCR/AdBlue systems for compliance.

The DLUB’s dual-loop EGR and SCR/AdBlue system ensures Euro 6 compliance but requires regular AdBlue top-ups and DPF regeneration cycles to avoid limp mode. VW 507 00 oil is mandatory to protect emissions hardware and turbo longevity. Early engines (pre-06/2017) may exhibit elevated oil consumption due to piston ring design—addressed via revised pistons per SIB 2017‑08. Extended short-trip driving can lead to carbon buildup in the intake and EGR cooler, necessitating periodic inspection. The timing chain is robust but relies on clean oil; adhere to 15,000 km or 12-month service intervals.
Oil Specs: Requires VW 507 00 (5W-30) specification (Volkswagen SIB 2017‑08). Not interchangeable with 504 00 or 502 00.
Emissions: Euro 6 certification applies to all DLUB models (2015–2020) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Output consistent across all DLUB applications (Volkswagen TIS Doc. 03G‑A210).

The Volkswagen DLUB was used across Volkswagen's Mk7/B8 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—revised engine mounts in the Tiguan and modified exhaust routing in the Passat—and from mid-2017 incorporated updated pistons to reduce oil consumption, creating minor interchange limits. Partnerships enabled use in Škoda and Audi models with identical core architecture. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil pump (Volkswagen TIS 03G‑A090). The 7th VIN digit is 'G' for 2.0L TDI engines, but full engine code must be verified visually or via OBD-II. Pre-06/2017 DLUB units use piston part number 03G 107 051 A; post-update units use 03G 107 051 B. Critical differentiation from DPCA/DPCB: DLUB uses dual-loop EGR and SCR with AdBlue, while earlier Euro 5 engines lack low-pressure EGR and SCR. Service parts for pistons and rings are production-date sensitive per SIB 2017‑08.
The DLUB's primary reliability risk is elevated oil consumption in early builds, with elevated incidence in high-mileage or short-trip usage. Volkswagen internal field data from 2017 indicated a subset of pre-mid-2017 engines consuming >0.5 L/1,000 km, while UK DVSA MOT data shows SCR/AdBlue system faults as a growing cause of emissions failures. Extended oil change intervals and low-quality oil accelerate piston ring coking, making adherence to VW 507 00 and service schedules critical.
