The Citroen HMM (EB2FAD) is a 1,199 cc, inline — three petrol engine produced between 2016 and 2023 as part of PSA Peugeot Citroën's EB engine family. It features a dual overhead camshaft (DOHC), 12 — valve configuration, and multi — point fuel injection (MPFI), delivering 55 kW (75 PS) at 5,500 rpm with 118 Nm of torque available from 2,750 rpm. This compact powerplant was engineered for lightweight urban mobility and optimal fuel efficiency in entry — level superminis.

All production years 2016–2023 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/8890).
The Citroen HMM (EB2FAD) is a 1,199 cc inline-three petrol engine developed for lightweight city cars (2016–2023). It uses multi-point fuel injection and a DOHC 12-valve layout to deliver balanced performance and efficiency. Engineered to meet Euro 6 standards, it prioritizes simplicity, low cost, and ease of maintenance in entry-level applications.

The Citroen HMM (EB2FAD) was used across Citroen's C3 platform with transverse mounting and shared with Peugeot under PSA Group commonality agreements. This engine received platform-specific calibrations—slightly tuned throttle response in the C3 and revised exhaust tuning in the 208—and from 2019 the updated C3 adopted a redesigned PCV system and updated ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The EB2FAD's primary reliability risk is intake manifold carbon buildup, with elevated incidence in vehicles subjected to frequent short trips. Internal PSA field reports from 2020 indicated a significant number of pre-2019 units required intake cleaning before 80,000 km, while UK DVSA data links a portion of emissions-related failures to lambda sensor degradation. Infrequent oil changes and delayed timing belt service increase mechanical stress, making fluid maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The EB2FAD is generally reliable when maintained properly. Key risks include intake carbon buildup in pre-2019 models and timing belt failure if service intervals are ignored. Using correct oil (PSA B71 2350) and replacing coolant every 3 years helps prevent overheating. Well-maintained engines can exceed 150,000 km without major issues.
Primary issues include intake manifold carbon buildup (especially pre-2019), timing belt failure, idle instability due to throttle body carbon, and water pump leaks. These are documented in PSA service bulletins. Regular maintenance—especially coolant and timing belt changes—significantly reduces failure risk.
The EB2FAD was used in the Citroen C3 (2016–2023) and shared with Peugeot 208 (2016–2019). It was phased out in favor of the newer PureTech turbocharged engines. Production spanned from 2016 to 2023, primarily in Euro 6-compliant A-segment hatchbacks.
Limited tuning potential exists. ECU remapping offers minimal gains due to the 12-valve DOHC design. Performance upgrades typically include performance air filters, exhaust systems, and throttle body modifications. However, gains are modest (+3–5 kW), and reliability may be compromised without supporting cooling and fuelling upgrades.
In combined driving, expect 5.8–6.5 L/100km (43–49 mpg UK). The C3 1.2 averages ~6.1 L/100km in mixed use. Real-world economy depends on driving style—aggressive use can exceed 8 L/100km. Highway cruising is more efficient, often achieving 5.2–5.6 L/100km.
Yes. The EB2FAD is an interference engine. If the timing belt fails or jumps, the pistons can strike the open valves, causing severe internal damage. The timing belt must be replaced every 60,000 km or 4 years—ignoring this risks catastrophic engine failure.
PSA specifies SAE 0W-20 oil meeting PSA B71 2350 standard. This low-viscosity synthetic oil ensures proper lubrication of the DOHC valvetrain and timing components. Oil changes should be performed every 15,000 km or annually to maintain engine longevity and prevent sludge buildup.
