Belts, airbags, air conditioning and campaigns on the Fiat StiloKnown weak points

Engine / equipment: Fiat Stilo (petrol and JTD)
Period mentioned: 2001–2007
Symptoms: Airbag system faults; an air-conditioning condenser that corrodes through; water in the boot and faulty gearboxes; a dashboard that turns sticky; timing belt, tensioners and pulleys to replace every 58,000–64,000 km together with the belt-driven water pump: if the pump fails, the belt comes off.
Possible cause described: Honest John calls it a car with too many problems. Recalls: radiator fan control unit with a short-circuit and overheating risk (2003), curtain airbags that could deploy by themselves (2003) and front springs that could break (2006).
Check for the garage: Check that the air conditioning blows cold and there are no airbag warnings; ask when the belt and pump were last changed; check campaigns by VIN.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 1.9 JTD / Multijet (Diesel)

1.9/2.4 JTD intake flaps, EGR and flywheelIntake / EGR / flywheel

Engine / equipment: 1.9 JTD / Multijet (8 and 16 valves), 2.4 JTD and JTDm in Fiat, Alfa Romeo 147, 156, 159, GT and Brera, Lancia and the Opel 1.9 CDTI
Period mentioned: 1997–2012
Symptoms: Power loss, rough idle and an engine light with “swirl actuator malfunction”; soot around the intake manifold; vibration and knocks in low gears (dual-mass flywheel).
Possible cause described: On the 16-valve 1.9 and 20-valve 2.4, the intake flaps seize with EGR soot and oil, and the control rod comes off as its plastic bushes wear. The EGR fouls in town use and the dual-mass flywheel wears between 80,000 and 150,000 km. The 8-valve 1.9 has no flaps.
Check for the garage: Check the rod and flap operation on top of the manifold, read actuator codes, inspect the EGR and listen to the flywheel when starting and stopping.
Cost cited in the source: Intake manifold: €400–900 in parts; EGR cleaning: €150–250A rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: 80,000–150,000 km. This is not a maintenance interval and does not predict a failure.
