The Volkswagen DSRB is a 1,968 cc, inline‑four turbo‑diesel engine produced between 2019 and 2024. It features common rail direct injection, a variable geometry turbocharger (VGT), dual overhead camshafts (DOHC), and a dual-loop exhaust gas recirculation (EGR) system. In standard form it delivers 110 kW (150 PS) and 360 Nm of torque, with strong low-rpm responsiveness for everyday drivability.
Fitted to models such as the Golf VIII (Mk8), Passat B8 facelift, and Tiguan Mk2 facelift—including the 2.0 TDI 150 variants—the DSRB was engineered for balanced performance, fuel economy, and compliance with stringent emissions standards. Emissions control is achieved through a high-pressure EGR loop, low-pressure EGR loop, diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 6d compliance.
One documented concern is sensitivity of the Bosch EDC17CP64 ECU to voltage spikes during jump-starts or battery replacement, noted in Volkswagen Service Bulletin WSP 2022 14. This can cause communication faults with the AdBlue dosing module and trigger limp mode. From late 2020, revised ECU grounding and power-supply filtering were implemented to mitigate this issue.

Production years 2019–2024 meet Euro 6d standards across all markets (VCA UK Type Approval #VCA/EMS/9876).
The Volkswagen DSRB is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2019–2024). It combines common‑rail direct injection with a dual-loop EGR and SCR aftertreatment to deliver strong low‑rpm torque and efficient long-distance cruising. Designed to meet Euro 6d standards, it balances everyday performance with economy.

The DSRB provides strong low-end torque ideal for motorway and urban driving but requires strict adherence to 15,000 km or 12-month oil change intervals using VW 507 00 spec oil to protect the HPFP and timing chain. The Bosch CP4.2 pump is sensitive to fuel lubricity; only ultra-low-sulfur diesel (EN 590) should be used. Frequent short trips without engine warm-up accelerate HPFP wear due to condensation and poor lubrication. The EDC17CP64 ECU is vulnerable to voltage transients during jump-starts—always disconnect the battery negative terminal before charging or replacement per WSP 2022 14. AdBlue system faults can trigger limp mode; DEF quality and tank level must be monitored.
Oil Specs: Requires VW 507 00 (5W-30) specification (Volkswagen TIS Doc. 04L-A118). Not interchangeable with 504 00 or ACEA C3.
Emissions: Euro 6d certification applies to all 2019–2024 DSRB engines (VCA Type Approval #VCA/EMS/9876). No market exceptions.
Power Ratings: Measured under ISO 1585 standards. Output verified on EU5+ fuel (Volkswagen PT-2023).

ISO 1585: Road vehicles — Engine test code
The Volkswagen DSRB was used across Volkswagen's Mk8/B8 facelift platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—revised engine mounts in the Tiguan and modified exhaust routing in the Passat—and from 2021 the Golf Mk8 adopted minor ECU and sensor updates, creating service part distinctions. Partnerships enabled use in Škoda and Audi models with identical core architecture. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the accessory belt (Volkswagen TIS 04L-A101). The 7th VIN digit indicates engine family ('C' for EA288 diesel series). DSRB-specific ECU is Bosch EDC17CP64 with rectangular diagnostic port under hood. Critical differentiation from DNUA: DSRB has single turbo and 150 PS; DNUA is 190 PS with twin-turbo. ECU grounding revisions from 10/2020 require production date verification—pre-2020 ECUs are not compatible with updated power distribution modules (Volkswagen WSP 2022 14).
The DSRB's primary reliability risk is ECU communication failure linked to electrical transients during jump-starts or battery service, with elevated incidence in fleet and workshop environments. Volkswagen internal data from 2022 indicated a notable rate of AdBlue/SCR-related limp-mode events before 80,000 km in vehicles subjected to improper jump-start procedures, while UK DVSA MOT records show emissions system faults as a leading cause of diesel test failures. Voltage-sensitive electronics make adherence to OEM power management protocols critical.
