FIAT 940-C1-000 engine (2017–2021) – Specs, Problems & Compatibility Database

The Fiat 940 C1.000 is a 999 cc, inline‑three turbocharged petrol engine produced between 2017 and 2021. It features a DOHC 12‑valve design with direct fuel injection and a small turbocharger, delivering a blend of efficiency and spirited performance for its size. The compact three‑cylinder layout contributes to a lightweight package and distinctive engine note, while the turbocharger provides strong low‑end torque for responsive urban driving.

Fitted primarily to the Fiat 500 (312) and Panda (141) models, the 940 C1.000 was engineered for drivers seeking peppy performance in a city car format. Emissions compliance was achieved through a close-coupled three-way catalytic converter and gasoline particulate filter (GPF), allowing it to meet stringent Euro 6d-TEMP standards across its production run.

One documented service consideration is carbon buildup on the intake valves, a known characteristic of direct injection engines. This issue, referenced in Fiat Technical Service Bulletin TSB‑17‑033, can lead to rough idle or reduced performance if not addressed. Fiat recommended periodic inspection and cleaning for vehicles operating primarily in urban, stop-start conditions.

Compliance Note:

Production years 2017–2021 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/8765).

940-C1-000 Technical Specifications

The Fiat 940 C1.000 is a 999 cc inline‑three turbocharged petrol engineered for city cars (2017-2021). It combines direct fuel injection with a small turbocharger to deliver responsive low-end power and efficient urban running. Designed to meet Euro 6d-TEMP standards, it balances compact dimensions with modern emissions control.

Practical Implications

The turbocharged design offers strong low-RPM torque ideal for city driving but requires strict adherence to 90,000 km timing belt replacement intervals. Fiat 9.55535-S2 (5W-40) oil is mandatory to protect the turbocharger and variable valve timing system. The direct injection system is susceptible to intake valve carbon buildup, particularly in vehicles used for frequent short trips; periodic cleaning per TSB 17-033 is recommended. The Garrett GT0632SZ turbocharger requires a 30-second idle cooldown after sustained high-load driving to prolong bearing life.

Data Verification Notes

Oil Specs: Requires Fiat 9.55535-S2 (5W-40) specification (Fiat TSB 17-033). Meets ACEA C3 requirements.

Emissions: Euro 6d-TEMP certification applies to all 2017–2021 models (VCA Type Approval #VCA/EMS/8765). No market-specific variations.

Power Ratings: Measured under SAE J1349 standards. Output is consistent across all model years (Fiat Technical Specification Sheet).

Identification Guidance

Locate the engine code stamped on the front face of the cylinder block, just below the exhaust manifold (Fiat Workshop Manual 500). The 8th digit of the VIN is 'D' for the 1.0L turbo petrol engine. Visually, it is identifiable as a compact 3-cylinder engine with a black plastic intake manifold, visible turbocharger on the exhaust side, and "T-Jet" or "Turbo" badging. Critical differentiation from the 843 A1.000: The 940 C1.000 has a turbocharger and intercooler piping; the 843 is naturally aspirated. Service parts for the timing system and turbocharger are specific to the 940 engine code.

Timing Belt Service

Evidence:

Fiat Workshop Manual 500 (312)

Interval:

Replace timing belt, tensioner, and idler pulleys every 90,000 km or 6 years, whichever comes first (Fiat Workshop Manual).

Critical Component:

Inspect turbocharger oil feed and return lines for leaks or coking during major services.
Intake Valve Cleaning

Evidence:

Fiat TSB 17-033

Requirement:

Perform intake valve cleaning every 60,000 km for vehicles used primarily in urban/stop-start conditions, as per TSB 17-033.

Common Reliability Issues - FIAT 940-C1-000

The 940 C1.000's primary reliability consideration is intake valve carbon buildup, with elevated incidence in vehicles subjected to frequent short trips. This issue, documented in Fiat TSB 17-033, can lead to drivability complaints if neglected. Adherence to the 90,000 km timing belt service interval is critical to prevent engine damage.

Intake valve carbon buildup
Symptoms: Rough idle, hesitation on acceleration, reduced fuel economy, illuminated check engine light (codes P0300-P0303).
Cause: Lack of fuel washing over intake valves due to direct injection, exacerbated by low-temperature, short-trip driving cycles.
Fix: Perform walnut shell or chemical intake valve cleaning procedure as outlined in Fiat TSB 17-033; reset ECU adaptations.
Turbocharger wastegate actuator failure
Symptoms: Loss of boost pressure, whistling noise under acceleration, illuminated check engine light (codes P0299, P0234).
Cause: Mechanical wear or carbon fouling of the wastegate linkage or actuator diaphragm, preventing precise boost control.
Fix: Replace the turbocharger actuator assembly or, if severe, the entire turbocharger unit with an OEM-specified part.
Timing belt tensioner wear
Symptoms: Whining or rattling noise from front of engine, especially at idle or low RPM.
Cause: Bearing wear or hydraulic damping failure within the automatic tensioner assembly over time and mileage.
Fix: Replace the timing belt, tensioner, and idler pulleys as a complete kit using OEM-specified parts per service schedule.
Gasoline particulate filter (GPF) clogging
Symptoms: Reduced engine power, increased fuel consumption, illuminated emissions warning light, frequent forced regenerations.
Cause: Insufficient exhaust temperature for passive regeneration, common in vehicles used exclusively for short urban trips.
Fix: Perform a forced regeneration using Fiat diagnostic equipment; if clogged beyond recovery, replace the GPF assembly.
