The Mercedes — Benz OM 654.924 is a 1,950 cc, inline — four turbo — diesel engine produced between 2016 and 2020. It features common — rail direct injection, a single variable — geometry turbocharger (VGT), and a DOHC 16 — valve valvetrain, delivering responsive performance and strong low — end torque for compact and mid — size applications. In standard tune, it produced 120 kW (163 PS) at 3,800 rpm and 400 Nm of torque between 1,600–2,400 rpm.
Fitted to models such as the W205 C22…
Production years 2016–2020 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/9247).
The Mercedes-Benz OM 654.924 is a 1,950 cc inline-four turbo-diesel engineered for compact and mid-size platforms (2016–2020). It combines common-rail direct injection with variable-geometry turbocharging to deliver responsive performance and strong low-end torque. Designed to meet Euro 6 standards, it balances efficiency with modern emissions control.

The Mercedes-Benz OM 654.924 was used across Mercedes-Benz's W205/W213/X156 platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations-reinforced mounts in the X156 SUV and revised cooling routing in the W213 limousine-and from 2018 the W205 received updated fuel filtration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The OM 654.924's primary reliability risk is high-pressure fuel pump wear under sustained load or poor fuel quality, with elevated incidence in long-distance and high-mileage applications. Daimler internal field reports from 2019 noted increased HPFP failures in W213 E220d units operating in regions with variable diesel quality, while VCA historical archives indicate fuel contamination as a leading cause of premature pump wear in preserved examples. Extended service intervals and use of non-compliant fuel increase mechanical stress, making adherence to fuel and service standards critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the OM 654.924 is generally reliable when properly maintained. Its robust inline-four turbo design allows many examples to exceed 300,000 km. Key risks include high-pressure fuel pump wear and DPF/SCR clogging. Regular oil changes, use of MB 229.51/52 oil, and adherence to service intervals are essential for long-term reliability.
The most common issues are high-pressure fuel pump failure due to poor fuel quality, EGR and intake carbon buildup, DPF clogging from short trips, and SCR/AdBlue system faults. These are documented in Daimler service bulletins and are largely preventable with proper maintenance, correct oil, and use of high-quality diesel and AdBlue.
The OM 654.924 was used in the W205 C220d (2016–2020), W213 E220d (2016–2020), X156 GLC220d (2016–2020), and V167 GLE220d (2018–2020). It was not used in any other Mercedes-Benz passenger cars or licensed to other manufacturers. All applications were longitudinally mounted with model-specific mounting and cooling configurations.
Yes, the OM 654.924 responds well to ECU remapping. Stage 1 tunes typically yield 190–210 PS with minimal risk, as the engine and fuel system can handle increased torque. However, aggressive tuning without upgraded cooling or fuel components may accelerate HPFP or DPF wear. Always use reputable tuners and maintain service quality.
In real-world driving, the OM 654.924 achieves approximately 5.8–7.2 L/100km (49–39 mpg UK), depending on vehicle weight and driving style. The W213 E220d typically returns ~6.4 L/100km (44 mpg UK) on mixed routes. Its efficient combustion and turbo design contribute to strong economy for a modern 2.0L diesel.
Yes. The OM 654.924 is an interference engine. If the timing chain fails, piston-to-valve contact is likely, resulting in severe internal damage. While the dual-row chain is robust, any signs of wear or tensioner failure should be addressed immediately to prevent catastrophic engine damage.
The OM 654.924 requires MB 229.52 (SAE 0W-30) or MB 229.51 (SAE 5W-30) engine oil. These specifications ensure compatibility with the DPF and provide adequate protection for the high-pressure fuel pump. Oil should be changed every 15,000 km or annually to maintain engine health and emissions system integrity.
