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.

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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The DJHB is generally robust with proper maintenance. Early models (pre-2017) are prone to high-pressure fuel pump wear, especially with poor fuel quality. Post-2017 revisions improved HPFP durability. Using correct oil (VW 504 00) and regular longer runs help prevent DPF and EGR issues. With adherence to service schedules, 200,000 km+ longevity is achievable.
The most frequent issues are high-pressure fuel pump wear, AdBlue/SCR system faults, EGR and intake carbon buildup, and turbo actuator sticking. These are documented in Audi service bulletins. Fuel pump issues stem from lubrication and fuel quality; SCR faults often result from low AdBlue. Regular inspection and correct fluid use mitigate most risks.
The DJHB was used in the Audi A3 (8V), A4 (B9), and Q3 (8U) from 2015 to 2020. It appears as 35 TDI in all variants. All models feature common-rail injection, VGT, and SCR with AdBlue. It is not used in S or RS models. The engine was phased out in favour of EA288 variants with improved emissions control.
Yes. The DJHB responds well to ECU remapping, with stage 1 tunes typically adding +25-40 kW. The EA288 block and internals are strong, but increased power raises exhaust temperatures. Upgraded cooling and careful tuning are recommended. Reputable tuners offer lifetime warranties. Avoid excessive tuning without supporting modifications.
In real-world conditions, expect 5.2–6.0 L/100km (45–39 mpg UK) depending on model and driving style. The A3 35 TDI achieves up to 56 mpg UK on highways. Combined figures range from 44–52 mpg UK. SCR system and DPF regeneration slightly reduce efficiency in city driving. Use of AdBlue does not affect fuel economy.
Yes. The DJHB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. While the double-row roller chain is designed for long life, any signs of chain wear or tensioner failure must be addressed immediately to prevent catastrophic engine failure.
The DJHB requires VW 504 00 or 507 00 specification oil (typically SAE 5W-30). This low-ash formulation is critical for DPF protection and longevity. Oil changes should be performed every 15,000 km or annually. Using non-compliant oil can lead to DPF clogging and increased maintenance costs.
