The Volkswagen DLTA 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 highway efficiency.
Fitted to models such as the Mk7 Golf, Passat B8, Tiguan Mk2, and Touran, the DLTA was designed for drivers prioritisin…
Production years 2015–2020 meet Euro 6 standards across all markets .
The Volkswagen DLTA 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 and AdBlue SCR aftertreatment to deliver strong low‑rpm torque and low NOx emissions. Designed to meet Euro 6 standards, it balances everyday performance with regulatory compliance.

The Volkswagen DLTA was used across Volkswagen's Mk7/B8 platforms with transverse mounting and shared with Škoda and SEAT under the MQB architecture. This engine received platform-specific adaptations—revised engine mounts in the Passat and modified coolant routing in the Tiguan—and from 2018 the updated HPFP and ECU calibration, creating minor service part distinctions. 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 DLTA is generally robust when maintained properly, but pre-2018 models are prone to HPFP wear if used mainly for short trips or with poor-quality diesel. Post-2018 revisions improved fuel pump durability. Regular oil changes with VW 507 00 oil and consistent AdBlue use are essential for longevity.
Key issues include high-pressure fuel pump wear, AdBlue system faults (low fluid or dosing errors), EGR/intake carbon buildup, and minor oil leaks. These are documented in Volkswagen service bulletins and align with DVSA MOT failure trends for Euro 6 diesels.
The DLTA powered the Golf VII, Passat B8, Tiguan Mk2, and Touran from 2015–2020 with 150 PS output. It was also used in Škoda Octavia III and SEAT Leon Mk3 under the MQB platform, always paired with Euro 6 SCR/AdBlue aftertreatment.
Aftermarket ECU tuning is common on the DLTA 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 PS, 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), assuming regular highway use for DPF regeneration and quality diesel.
Yes. Like all modern VW diesel engines, the DLTA is an interference design. Timing chain failure—though rare due to front-mounted low-wear design—could cause piston-to-valve contact and catastrophic damage. Prompt attention to any timing-related warnings is essential.
Volkswagen mandates VW 507 00 (5W-30) low-ash synthetic oil. This specification is critical for DPF/SCR longevity and HPFP lubrication. Never substitute with 504 00 or generic ACEA C3 oils, as they may cause aftertreatment damage or pump wear.
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.
