Timing Belt Interval:
Recommended replacement every 120,000 km (75,000 miles) or 5 years. Crucial to follow due to interference engine design.
Engine Oil Type:
API SL or SM, ACEA A3/B3 or A3/B4, viscosity typically 5W-30 or 5W-40 (refer to manual for exact specification, e.g., PSA B71 2290 for diesel or equivalent petrol spec).
Coolant Type:
Ethylene glycol based coolant with long-life inhibitors, typically orange or purple. Refer to PSA specification (e.g., PSA S71 2710).
Convertible Roof:
The complex multi-position roof mechanism can be prone to issues with motors, seals, hydraulic lines, and sensor failures, requiring meticulous maintenance and careful operation.
Electrical Gremlins:
As with many French cars of this era, some owners report intermittent electrical faults, often related to body control modules, switches, or wiring harness connections.
Suspension Wear:
Front suspension components like ball joints and bushings can wear over time, impacting handling and ride comfort.
