Engines: 1.4 / 1.6 / 1.8 / 2.0 TS (Petrol)
Applies if: 145/146 after 1997 with the 2.0 Twin Spark 16V engine and matching noise; published workshop diagnosis, not a recall or a quantified incidence. Do not extrapolate to other engines without checking.

- Only the configurations, markets and VINs specified in each association.
- Period mentioned
- Specific production period stated in the condition and evidence.
- Symptoms
- Diesel-like rattle on cold startup.
- Possible cause described
- The garage identifies the variator as a possible noise source; persistent warm noise requires checking bearings.
- Check for the garage
- Verify engine, oil and cold/warm noise; confirm source before replacing the variator during timing belt work.
- Cost cited in the source
- No verified estimate. Confirm repair eligibility and terms by VIN.A rough figure from the original database, not an up-to-date quote.

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.
