The Volkswagen DAJB is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2012 and 2019. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivers 162 kW (220 PS) and 350 Nm of torque, with strong mid‑range pull enabled by its twin‑scroll turbocharger.
Fitted to models such as the Mk7 Golf R, Mk3 Tiguan, and Audi S3 (8V), the DAJB was engineered for high performance with everyday usabil…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models meet Euro 6 compliance depending on market .
The Volkswagen DAJB is a 1,984 cc inline‑four turbocharged petrol engine engineered for performance hatchbacks and SUVs (2012–2019). It combines direct injection (TSI) with a twin‑scroll turbocharger to deliver responsive power and strong mid‑range torque. Designed to meet Euro 5 and Euro 6 emissions standards, it balances sporty performance with regulatory compliance.

The Volkswagen DAJB was used across Volkswagen's Mk7 and Mk3 platforms with transverse mounting and shared with Audi under the Volkswagen Group modular strategy. This engine received platform-specific adaptations—reinforced engine mounts in the Golf R and modified exhaust routing in the Tiguan—and from 2016 the facelifted Golf R adopted updated cam followers and oil jets, creating minor interchange limits. Partnerships enabled Audi S3 and SEAT Cupra variants to use identical long blocks. 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 DAJB is generally robust when maintained properly. Early units (2012–2015) had cam follower wear issues, but post-2016 revisions improved durability. Using correct oil (VW 502/504) and changing it regularly (every 15,000 km) greatly reduces risk. The timing chain is maintenance-free and rarely problematic.
Top issues include high-pressure fuel pump cam follower wear, turbo wastegate rattle, minor carbon buildup on intake valves, and plastic coolant flange leaks. These are documented in Volkswagen service bulletins, especially SIB 2015‑07 for the cam follower concern.
The DAJB powered the Golf R (Mk7, 2013–2019), Tiguan 2.0 TSI 4Motion (2016–2019), and was shared with Audi S3 (8V, 2013–2016) and SEAT León Cupra (Mk3, 2014–2018). All are transverse-mounted applications within the Volkswagen Group MQB/MLB platforms.
Aftermarket ECU tuning is common on the DAJB 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 R, expect ~8.5 L/100km (city) and ~6.0 L/100km (highway), or about 33 mpg UK combined. Real-world mixed driving typically yields 28–35 mpg (UK). Economy drops significantly with aggressive driving due to the engine’s performance orientation.
Yes. The DAJB is an interference engine. If the timing chain were to fail (extremely rare), piston-to-valve contact would cause catastrophic damage. However, the chain is designed for life-of-engine service with proper oil maintenance.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Always use a high-quality TSI-approved oil and change it every 15,000 km or annually to protect the cam follower and turbocharger.
