DuoSelect / Cambiocorsa robotised gearbox and timing chain on the 4.2 V8

Engine / equipment

Maserati 4.2 / 4.7 V8: Quattroporte V (and Coupé / Spyder 4200 with Cambiocorsa)

Period mentioned

2001–2012

Symptoms

Low-speed jerks and hesitation from the robotised gearbox; a clutch worn out before about 100,000 km in town; metallic chain rattle on a cold start; oil leaks from valve covers and sump.

Possible cause described

The DuoSelect gearbox’s hydraulic actuator is the part that fails most; the clutch wears quickly in town. A worn timing chain can jump and destroy the engine: replacement at around 100,000 km is recommended. Cheap oil or late changes damage the camshafts.

Check for the garage

Read clutch wear with the diagnostic tool, listen to the chain when cold and check the oil- and chain-change history.
