The Volkswagen DDAA is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2020. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivered 110 kW (150 PS) and 250 Nm of torque, with responsive mid‑range performance ideal for compact and mid‑size applications.
Fitted to models such as the Mk7 Golf, Mk2 Touran, and Mk3 Octavia—including the Golf 1.4 TSI 150 PS and Octavia 1.4 TS…
Production years 2012–2014 meet Euro 5 standards; 2015–2017 models meet Euro 6b; 2018–2020 models meet Euro 6d-TEMP with GPF .
The Volkswagen DDAA is a 1,395 cc inline‑four turbocharged petrol engineered for compact and mid‑size models (2012–2020). It combines direct fuel injection (TSI) with a single turbocharger to deliver strong mid‑range torque and efficient highway cruising. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with fuel economy.

The Volkswagen DDAA was used across Volkswagen's Mk7/Mk3 platforms with transverse mounting and shared with Škoda and SEAT. This engine received platform-specific adaptations—revised cooling in the Golf and reinforced mounts in the Octavia—and from 2018 the facelifted Golf Mk7.5 adopted a gasoline particulate filter (GPF), creating minor software and hardware interchange limits. Partnerships enabled Škoda's 1.4 TSI 150 PS and SEAT's Leon 1.4 EcoTSI to use identical hardware. 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 DDAA offers strong performance and efficiency, but pre-2017 models are prone to HPFP cam follower wear. Post-2017 revisions improved durability. With correct oil (VW 502 00/504 00), regular induction cleaning, and proper driving cycles for GPF models, it can be dependable beyond 200,000 km.
Top issues include HPFP cam follower wear, intake valve carbon buildup, GPF clogging (2018+), and PCV valve failure in the rocker cover. These are documented in Volkswagen service bulletins 2016‑03‑OIL and 2017‑11‑GPF.
The DDAA appears in the Golf Mk7 (1.4 TSI 150 PS), Touran II, Škoda Octavia III, and SEAT Leon III from 2012–2020. It’s part of the EA211 TSI family and was never used in Audi or Porsche applications.
Aftermarket ECU tuning is common on the DDAA 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.
In a Golf 1.4 TSI 150 PS, expect ~6.8 L/100km (city) and ~4.7 L/100km (highway), or about 48 mpg UK combined. Real-world mixed driving typically returns 45–50 mpg (UK) with conservative use.
Yes. The DDAA is an interference engine. Timing chain failure—though rare—can cause piston-to-valve contact and catastrophic damage. However, the front-mounted chain is robust with proper oil maintenance.
Volkswagen specifies SAE 5W‑30 or 5W‑40 oil meeting VW 502 00 (non-GPF) or 504 00 (GPF) standards. Using non-approved oil risks HPFP and turbo wear. Change every 15,000 km or annually.
