The Volkswagen DBGA 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 performance and motorway efficiency.
Fitted to models such as the Mk7 Golf, Passat B8, and Tiguan Mk2—including the 2.0 TDI 150 variants—the DBGA was engin…
Production years 2015–2020 meet Euro 6 standards .
The Volkswagen DBGA 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 efficient cruising. Designed to meet Euro 6 standards, it balances everyday performance with economy.

The Volkswagen DBGA was used across Volkswagen's Mk7/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 routing in the Tiguan—and from 2018 minor ECU updates improved cold-start emissions, 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 DBGA is generally robust with proper maintenance, though early units (2015–mid-2017) had EGR cooler issues. Post-2017 revisions improved durability. Using VW 507 00 oil, quality diesel, and maintaining AdBlue levels are essential for longevity beyond 200,000 km.
Top issues include EGR cooler failure (pre-2017), AdBlue/SCR system faults, CP4.2 fuel pump wear from poor diesel, and DPF clogging from short trips. All are documented in VW service bulletins and technical updates.
The DBGA powered the Golf Mk7, Passat B8, and Tiguan Mk2 (all 2.0 TDI 150 variants) from 2015–2020. It was also used in Škoda Superb III and Audi A3 8V under the MQB platform with identical mechanical specs.
Aftermarket ECU tuning is common on the DBGA 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 ~4.8 L/100km (city) and ~3.6 L/100km (highway), or ~59 mpg UK combined. Real-world mixed driving typically returns 50–58 mpg (UK) when AdBlue and DPF systems are functioning correctly.
Yes. Like all modern VW diesel engines, the DBGA 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 5W-30 synthetic oil meeting VW 507 00 specification. This low-ash oil protects the DPF and turbo. Never substitute with 504 00 or generic ACEA C3 oils, as they may increase ash buildup and reduce emissions system life.
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.
