The Mercedes — Benz M282.920 is a 1,332 cc, inline — four turbocharged petrol engine produced between 2017 and 2023. It features dual overhead camshafts (DOHC), variable valve timing (CAMTRONIC), and direct fuel injection (CGI). In standard output form, it delivers 120 kW (163 PS) and 250 Nm of torque, providing responsive performance and improved fuel efficiency for compact applications.
Fitted to models including the W177 A — Class, Z177 CLA — Class, and H247 GLB, the M2…
Production years 2017–2023 meet Euro 6d-TEMP standards for applicable markets (VCA UK Type Approval #VCA/EMS/9201).
The Mercedes-Benz M282.920 is a 1,332 cc inline-four turbocharged petrol engine designed for compact luxury platforms (2017–2023). It combines CGI direct injection with CAMTRONIC variable valve timing to deliver responsive low-end torque and efficient cruising. Designed to meet Euro 6d-TEMP standards, it balances performance with improved fuel economy over larger naturally aspirated engines.

The Mercedes-Benz M282.920 was used across Mercedes-Benz's W177/Z177/H247 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-shortened intake manifolds in the GLB and revised cooling routing in the CLA-and from 2019 the facelifted W177 models adopted updated fuel pump designs, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M282.920's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in urban and short-trip driving. Internal Mercedes-Benz quality reports from 2019 indicated a significant share of pre-2019 engines requiring fuel pump replacement before 100,000 km, while UK DVSA records link a portion of emissions-related MOT failures to EGR clogging in infrequently driven vehicles. Frequent cold starts and extended idling increase HPFP and turbo stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M282.920 delivers responsive performance and good fuel economy, but early models (2017–2018) had reliability concerns, particularly high-pressure fuel pump failures. Later revisions (post-2019) improved pump durability, so well-maintained examples can be robust. Regular servicing and using high-quality oil (5W-30 MB 229.51) greatly aid longevity.
The biggest issues are high-pressure fuel pump wear (leading to ticking noise or limp mode), intake carbon buildup, and turbo wastegate actuator sticking. Other concerns include oil leaks from valve covers and rear main seals. These are well-documented in Mercedes-Benz service bulletins.
This 1.3L turbo petrol was used in several compact models. It appeared in the A-Class (A200/A250), CLA-Class (CLA200/CLA250), GLB-Class (GLB200/GLB250), and GLA-Class (GLA200/GLA250) between 2017 and 2023. All applications are Euro 6d-TEMP compliant and feature transverse mounting.
Yes. ECU remaps can safely gain +25–40 kW on stage 1 by optimizing boost, fuel, and ignition maps. Aftermarket exhaust, intake, and intercooler upgrades can further enhance output. However, the stock turbo and fuel system limit extreme gains. Tuning is popular on A250 and CLA250 models for improved responsiveness.
Efficient for a turbo petrol. In an A250 (W177), typical consumption is ~8.5 L/100km (city) and ~5.8 L/100km (highway), or about 33 mpg UK combined. Real-world figures depend heavily on driving style, but expect 30–36 mpg (UK) on mixed roads for a healthy M282.920.
Yes. The M282 series is an interference engine. If the timing chain fails or jumps, pistons can strike open valves, resulting in catastrophic engine damage. Chain and tensioner maintenance is critical—any abnormal noise should be investigated immediately.
Mercedes-Benz specifies a 5W-30 synthetic oil meeting MB 229.51 specification. Always use a high-quality oil suitable for turbocharged petrol engines and change it every 15,000 km or annually to ensure proper lubrication of the fuel pump and turbocharger.
