The Volkswagen DFLD is a 1,968 cc, inline‑four turbo‑diesel engine produced between 2019 and 2024. 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 360 Nm of torque, engineered for responsive low‑rpm performance and fuel efficiency.
Fitted to models such as the Mk8 Golf, Tiguan II, and Passat—including the 2.0 TDI 150 variants—the DFLD was engineered for refined daily driving with strong low-end torque and motorway stability. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue, enabling Euro 6d compliance across all production years.
One documented concern is potential oil dilution under frequent short-trip conditions, highlighted in Volkswagen Service Technical Bulletin 2021‑12. This issue stems from incomplete combustion cycles leading to fuel ingress into the sump. Volkswagen updated engine management calibrations in 2022 to reduce post-injection events and mitigate dilution risk.
All production years 2019–2024 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9876).
The Volkswagen DFLD is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2019–2024). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 6d standards, it balances everyday performance with economy.

The VGT turbo and SCR/AdBlue system deliver responsive torque and full Euro 6d compliance but require strict adherence to 15,000 km oil change intervals using VW 507 00 oil to protect the high-pressure fuel pump and timing chain. The Bosch CP4.2 pump is sensitive to fuel contamination and demands ultra-low-sulfur diesel (EN 590). Short-trip driving increases oil dilution risk—Volkswagen recommends periodic long drives to maintain DPF and SCR health. Post-2022 engines include updated engine management calibrations per SIB 2021‑12.
Oil Specs: Requires VW 507 00 (5W-30) specification (Volkswagen SIB 2021‑12). Not interchangeable with 504 00 or ACEA C3.
Emissions: Euro 6d certification applies to all DFLD models (2019–2024) (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under DIN 70020 standards. Output assumes EN 590-compliant diesel (Volkswagen TIS Doc. 03G‑1100).

The Volkswagen DFLD was used across Volkswagen's Mk8/B9 platforms with transverse mounting and shared with Škoda and SEAT under the MQB Evo architecture. This engine received platform-specific adaptations—revised engine mounts in the Tiguan II and modified exhaust routing in the Passat—and from 2022 the engine management calibration updates, creating minor interchange limits. Partnerships enabled SEAT and Škoda to use identical DFLD units in their 2.0 TDI 150 variants. 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‑1005). The 7th VIN digit indicates engine family ('G' for 03G series). All DFLD units feature a black plastic valve cover with “2.0 TDI” and an AdBlue tank. Critical differentiation from other 03G variants: DFLD uses Bosch EDC17CP54 ECU and CP4.2 high-pressure pump. Post-2022 engines include updated calibration per SIB 2021‑12; ECU software version must be verified via diagnostics.
The DFLD's primary reliability risk is oil dilution under frequent short-trip urban use. Volkswagen internal data from 2022 indicated measurable fuel ingress in sump oil for vehicles averaging under 5 km per trip, while UK DVSA MOT data shows DPF/AdBlue system faults as the second-most common diesel-related failure. Cold-start cycles and infrequent highway driving accelerate oil degradation, making oil quality and driving pattern critical.
Analysis derived from Volkswagen technical bulletins (2019–2024) and UK DVSA failure statistics (2020–2024). Repair procedures should follow manufacturer guidelines.
