The Volkswagen DFLA 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 — end pull and highway efficiency.
Fitted to models such as the Mk7 Golf, Mk3 Touran, and T6 Transporter, including the 2.0 TDI 150 variants, the DFLA was engineer…
All production years 2015–2020 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen DFLA is a 1,968 cc inline‑four turbo‑diesel engineered for compact and MPV applications (2015–2020). 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 6 standards via SCR/AdBlue and DPF, it balances performance with strict emissions compliance.

The Volkswagen DFLA was used across Volkswagen's Mk7/T6 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—reinforced mounts in the T6 Transporter and revised cooling in the Golf SV—and from 2018 the HPFP and ECU calibration were updated, creating service part distinctions. Partnerships enabled use in SEAT and Škoda models under different engine codes. All adaptations are documented in OEM technical bulletins.
The DFLA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using non-EN 590 diesel or extended service intervals. Volkswagen internal data from 2018 indicated a notable share of pre-2018 DFLA engines requiring HPFP replacement before 100,000 km, while UK DVSA records show AdBlue system faults as a growing MOT failure category. Poor fuel quality and infrequent oil changes accelerate HPFP wear, making adherence to VW 507 00 oil and 15,000 km service intervals critical.
Analysis derived from Volkswagen technical bulletins (2015–2020) and UK DVSA failure statistics (2018–2023). 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 DFLA is generally robust when maintained correctly, but early units (2015–2017) are prone to HPFP failure. Post-2018 revisions improved fuel system durability. Using EN 590 diesel, VW 507 00 oil, and adhering to 15,000 km service intervals greatly enhances longevity.
Top issues include high-pressure fuel pump failure, AdBlue system faults (dosing valve crystallisation), DPF regeneration problems, and EGR cooler leaks. These are documented in Volkswagen SIB 2017‑09‑01 and TIS service procedures.
The DFLA appears in the Golf VII, Touran III, T6 Transporter, and Caddy IV (2015–2020) as the 2.0 TDI 150. It was also used in SEAT Leon Mk3 and Škoda Octavia III under shared platform agreements within the Volkswagen Group.
Yes. Stage 1 ECU remaps typically yield +20–30 kW (180–190 PS) safely, as the stock internals handle increased torque. However, tuning increases HPFP and turbo stress—only proceed with updated fuel system components and high-quality diesel.
Excellent. In a Golf 2.0 TDI 150, expect ~4.8 L/100km (city) and ~3.6 L/100km (highway), or ~58 mpg UK combined. Real-world mixed driving typically returns 50–55 mpg UK when DPF/AdBlue systems are functioning properly.
Yes. The DFLA is an interference design. Timing chain failure—though rare due to front-mounted chain—can cause piston-to-valve contact and catastrophic damage. Immediate attention to timing-related noises is essential.
Volkswagen mandates VW 507 00 (5W‑30) low-ash synthetic oil. This specification is critical for DPF/AdBlue compatibility and HPFP lubrication. Never substitute with older specs like 505 01 or non-approved oils.
