The Fiat 552 63 088 is a 1,248 cc, inline — four diesel engine produced between 2014 and 2018. It belongs to Fiat's MultiJet II family, featuring high — pressure common — rail direct injection, dual overhead camshafts (DOHC), and 16 valves. In standard tune, it delivers 70 kW (95 PS) at 4,000 rpm and 200 Nm of torque at 1,500 rpm, providing responsive low — end pulling power ideal for urban and light — duty applications.
Fitted primarily to the Fiat 500L (2015–2018), Fiat Tipo (201…
All production years (2014–2018) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/5687).
The Fiat 552 63 088 is a 1,248 cc inline-four turbo-diesel engine engineered for compact and small family vehicles (2014–2018). It combines MultiJet II common-rail injection with DOHC 16-valve architecture to deliver strong low-RPM torque and responsive drivability. Designed to meet Euro 5 emissions standards, it prioritises fuel economy, serviceability, and durability in mixed driving conditions.

The Fiat 552 63 088 was used across Fiat's 552-series platforms with transverse mounting and shared architecture with Lancia derivatives. This engine received platform-specific adaptations-shorter intake manifolds in the 500L and revised ECU tuning in the Tipo-and from 2016 the updated tensioner design improved belt reliability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 552 63 088's primary reliability risk is timing belt tensioner wear, with elevated incidence in hot climates and extended service cycles. Internal Fiat quality reports from 2017 indicated a significant number of pre-2016 engines required premature belt replacement before 100,000 km, while VCA MOT data links a notable share of emissions failures to DPF clogging in high-mileage units. Infrequent oil changes and poor fuel quality increase turbo and EGR stress, making adherence to service intervals and fuel specifications critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 552 63 088 is generally reliable when maintained properly, but pre-2016 models are susceptible to timing belt tensioner failure if service intervals are exceeded. Later revisions (post-2016) feature improved tensioner durability. Regular oil changes, use of EN 590 diesel, and timely belt replacement every 120,000 km or 6 years ensure long-term reliability.
The most documented issues are timing belt tensioner wear, DPF clogging, EGR valve fouling, and turbo actuator sticking. These are confirmed in Fiat service bulletins and field reports. Carbon buildup and sensor degradation are common in high-mileage units; regular highway driving helps maintain DPF health.
This 1.3L diesel engine was used in the Fiat 500L (2015–2018), Tipo (2016–2018), and Lancia Ypsilon (2015–2018). All models are Euro 5 compliant, as confirmed by VCA Type Approval #VCA/EMS/5687.
Yes. ECU remaps can yield +15–25 kW by optimizing boost, injection timing, and DPF regeneration logic. Gains of 115–120 PS are achievable with supporting mods. Over-tuning without intercooler or fuel system upgrades risks turbo and injector damage. Conservative tuning is advised for daily drivers.
In a Fiat 500L or Tipo, combined consumption is approximately 4.6 L/100km (61.3 mpg UK). City driving may see 5.6 L/100km (50.4 mpg), while highway runs can achieve 4.0 L/100km (70.8 mpg). Real-world economy depends on driving style, but 55–65 mpg (UK) is typical for well-maintained units on mixed routes.
Yes. The 552 63 088 is an interference engine. If the timing belt fails or jumps, pistons can contact open valves, resulting in bent valves or cylinder head damage. Adhering to the 120,000 km or 6-year replacement interval is essential to prevent costly internal repairs.
Fiat specifies SAE 5W-40 oil meeting ACEA C3 or API CK-4 standards. Use of high-quality low-ASH oil is critical for DPF and EGR longevity. Change intervals should not exceed 15,000 km or 1 year to protect the turbocharger and timing components.
