The Lancia 312 A2.000 is a 1,998 cc, inline‑four petrol engine produced between 2003 and 2010. It features a twin‑cam (DOHC) 16‑valve cylinder head and Magneti Marelli IAW 59F electronic fuel injection, delivering responsive performance. The crossflow cylinder head design promotes efficient gas exchange for strong mid — range torque.
Fitted primarily to the Lancia Musa MPV, the 312 A2.000 was engineered for smooth, refined power delivery suitable for urban and family…
Production years 2003–2010 meet Euro 4 emissions standards as per EU Regulation 98/69/EC and subsequent amendments.
The Lancia 312 A2.000 is a 1,998 cc inline‑four petrol engine engineered for compact MPVs (2003-2010). It combines a DOHC 16-valve crossflow head with Magneti Marelli IAW 59F fuel injection to deliver smooth, linear power. Designed to meet Euro 4 emissions standards, it prioritizes refinement and drivability.

The Lancia 312 A2.000 was used exclusively in the Lancia Musa (Type 312) MPV with transverse mounting. This engine received no major mechanical revisions during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
The 312 A2.000's primary reliability risk is neglect of the timing belt, with failure resulting in complete engine destruction. Magneti Marelli ignition system faults, particularly coil pack and crankshaft sensor failures, are a documented, common issue. Adherence to maintenance schedules is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 312 A2.000 can be very reliable if meticulously maintained. Its critical failure point is the timing belt; failure destroys the engine. The electronic ignition system is generally robust, but coil packs and crankshaft sensors are known wear items. With strict adherence to service intervals, especially for the belt and oil changes, these engines can last for hundreds of thousands of kilometers.
The most critical issue is timing belt failure. Common operational problems include failing ignition coil packs and crankshaft position sensors, which cause misfires and starting issues. Coolant leaks from hoses or the thermostat housing are also frequent concerns documented in service bulletins.
This engine was used exclusively in the Lancia Musa (Type 312), produced from 2003 to 2010. It powered the 2.0-liter petrol variants of this compact MPV, offering a balance of space and performance for family use.
Yes, within limits. Basic tuning involves remapping the Magneti Marelli ECU for optimized fuel and ignition timing. Significant power gains require internal modifications. The engine responds well to intake and exhaust upgrades. Most tuning focuses on improving throttle response and drivability rather than large power increases.
Fuel economy is moderate for its era. Expect approximately 11.0 L/100km (26 mpg UK) in city driving and 7.2 L/100km (39 mpg UK) on the highway for the 140 PS variant. Real-world figures vary significantly with driving style and vehicle condition.
Yes. This is an interference engine. If the timing belt breaks or slips, the pistons will collide with the open valves, causing severe and often catastrophic damage to the valves, pistons, and cylinder head. This makes timely belt replacement non-negotiable.
The manufacturer recommends a high-quality SAE 5W-40 full synthetic oil meeting API SJ/CF or ACEA A3/B3 specifications. Regular oil changes (every 10,000 km or annually) are crucial for engine longevity, especially for lubricating the timing belt tensioners and valve train.
