The Fiat 552 63 842 is a 1,956 cc, inline — four, turbocharged diesel engine produced between 2007 and 2012. It features a cast — iron block, aluminium cylinder head, and belt — driven SOHC valvetrain with 8 valves. In standard tune, it produces 88 kW (120 PS) at 4,000 rpm and 320 Nm of torque at 1,800 rpm, delivering strong low — end performance ideal for commercial and passenger applications.
Fitted to core Fiat models including the Ducato (244), Scudo (270), and Talento (270),…
All production models meet Euro 4 emissions standards (Directive 98/69/EC, VCA UK Type Approval #VCA/EMS/9678).
The Fiat 552 63 842 is a 1,956 cc inline-four turbocharged diesel engine designed for light commercial vehicles (2007–2012). It combines SOHC valvetrain architecture with common rail direct injection to deliver robust torque and fuel efficiency. Designed to meet Euro 4 emissions standards, it balances durability with serviceability for fleet and private use.

The Fiat 552 63 842 was used across Fiat's Ducato/Scudo platforms with transverse mounting and shared architecture with Peugeot and Citroën variants. This engine received platform-specific adaptations—reinforced mounts in the Ducato and revised intake manifolds in the Scudo—and from 2009 the facelifted Ducato X244 SW adopted a revised ECU mapping and secondary air injection, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 552 63 842's primary reliability risk is cam belt failure on neglected engines, with elevated incidence in high-mileage fleet vehicles. Internal Fiat service data from 2008 indicated a significant share of pre-2009 engines suffering belt-related damage beyond 75,000 km, while UK DVSA records show timing-related failures as a leading cause of MOT rejection for commercial models. Extended service intervals and aftermarket non-compliant belts increase risk, making adherence to replacement schedules critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, when properly maintained. The 552 63 842 is mechanically robust with a simple design, but timing belt integrity is critical. Pre-2009 models require vigilant belt maintenance due to manual tensioners. With regular oil changes, coolant service, and timely belt replacement, these engines often exceed 300,000 km. Avoid neglected examples with unknown service history.
The most frequent issues are cam belt failure (especially on pre-2009 models), DPF clogging due to urban driving, EGR valve fouling, and coolant leaks from the thermostat housing. These are documented in Fiat service bulletins and supported by DVSA inspection data. Preventive maintenance significantly reduces failure rates.
The 552 63 842 was used in the Fiat Ducato (244), Scudo (270), and Talento (270). It also powered the Peugeot Boxer (244) and Citroën Jumper (244) 2.0 HDi variants. Production spanned 2007–2012, with full Euro 4 compliance. The engine was phased out in favour of the 2.3 Multijet (136 kW) unit in later Ducato models.
Limited tuning potential exists. ECU remapping can yield modest gains (~15–25 kW) with improved throttle response. However, stock components (turbo, injectors, cooling) limit aggressive tuning. Most owners prioritise reliability over performance, keeping modifications minimal.
Real-world consumption averages 8.5–10.0 L/100km (28–33 mpg UK) in mixed driving. Highway efficiency improves to ~7.0 L/100km (~40 mpg UK). Urban delivery use may see higher consumption. Use of quality diesel meeting EN 590 helps maintain optimal economy and DPF health.
Yes. The 552 63 842 is an interference engine, meaning a broken cam belt can cause pistons to strike open valves, resulting in severe internal damage. This underscores the importance of strict adherence to the 60,000 km belt replacement interval.
Fiat specifies SAE 10W-40 engine oil meeting API CF or CH-4 standards. Use of quality synthetic or semi-synthetic oil is recommended, especially in high-temperature or stop-start conditions. Oil and filter should be changed every 15,000 km or 12 months to ensure engine longevity.
