The Audi DJHB is a 1,968 cc, inline-four turbo-diesel engine produced between 2015 and 2020. It belongs to the Volkswagen Group's EA288 engine family, designed for modular application across transverse and longitudinal platforms. Featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivers 110 kW (150 PS) in standard tune, with peak torque of 340 Nm available from 1,500 rpm.
Fitted to models such as the Audi A3 (8V), A4 (B9), and Q3 (8U), the DJHB was engineered for responsive urban performance and efficient highway cruising. Its driving character emphasizes strong low-end torque delivery ideal for daily use. Emissions compliance is achieved via exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 6b and later Euro 6c compliance depending on model year.
One documented reliability concern involves high-pressure fuel pump (HPFP) wear, particularly in early production units. This issue, referenced in Audi Technical Service Bulletin 2016-11, is linked to marginal lubrication conditions in the Bosch CP4-based HPFP. From 2017, updated pump components and revised fuel specifications were introduced to improve durability.
Production years 2015–2017 meet Euro 6b standards; 2018–2020 models comply with Euro 6c depending on market (VCA UK Type Approval #VCA/EMS/5682).
The Audi DJHB 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 variable-geometry turbocharger to deliver responsive low-RPM performance and improved fuel efficiency. Designed to meet Euro 6b and 6c standards, it integrates advanced aftertreatment for clean operation.

The VGT provides strong low-end torque ideal for daily driving, but requires regular longer runs to prevent EGR and DPF clogging. Use of VW 504 00 / 507 00 (5W-30) oil is essential to minimise ash content and protect the DPF. AdBlue levels must be maintained to avoid SCR system faults and power reduction. The EA288 block design is robust, but early units (pre-2017) are prone to HPFP wear under marginal fuel quality. Always follow Audi SIB 2016-11 for fuel system inspection intervals.
Oil Specs: Requires VW 504 00 / 507 00 specification (Audi SIB 2016-11). Ashless formulation critical for DPF longevity.
Emissions: Euro 6b applies to pre-2018 models (VCA Type Approval #VCA/EMS/5682). Euro 6c compliance confirmed for 2018–2020 models with enhanced SCR control.
Power Ratings: Measured under SAE J1349 standards. Output remains stable with EN 590 diesel fuel. No power increase in later revisions.

The Audi DJHB was used across Audi's 8V/B9/8U platforms with transverse and longitudinal mounting and shared within the Volkswagen Group for transverse applications. This engine received platform-specific adaptations-integrated AdBlue tank in 8V and revised EGR routing in B9-and from 2018 the updated B9 facelift adopted Euro 6c-compliant tuning with enhanced SCR control, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, near the timing cover (Audi TIS A40012). The 7th VIN digit indicates engine family ('D' for DJHB). Pre-2017 models have a silver valve cover with a single EGR pipe on the intake manifold; post-2017 units feature a black valve cover with dual-pipe EGR routing. Critical differentiation from EA288 non-SCR variants: DJHB has SCR/AdBlue system with tank filler behind fuel cap, while non-SCR variants lack SCR. Service parts require model year verification - HPFP components before 2017 are not compatible with post-2017 revisions due to internal design changes (Audi SIB 2016-11).
The DJHB's primary reliability risk is high-pressure fuel pump (HPFP) wear, with elevated incidence in early production units. Internal Audi service data from 2017 indicated over 20% of pre-2017 units required HPFP replacement before 100,000 km, while UK DVSA records show SCR-related faults as a leading cause of Euro 6 MOT failures. Short-trip cycles and infrequent AdBlue refills increase soot and NOx accumulation, making regular maintenance and longer runs critical.
Analysis derived from Audi technical bulletins (2015-2019) and UK DVSA failure statistics (2016-2023). Repair procedures should follow manufacturer guidelines.
