Whistle when accelerating from the turbo-to-cylinder-head gasket (Grecale MHEV)

Engine / equipment

Maserati Grecale 2.0 MHEV (M182), all years

Period mentioned

2022 onwards

Symptoms

High-pitched whistle when accelerating that rises with the revs; rarely, a smell of exhaust gas in the engine bay.

Possible cause described

In several cases the whistle came not from the turbo but from the gasket between the turbo and the cylinder head. Maserati says to check it with a road test and data logging before replacing the turbo (diagnostic sheet DS 26-04, March 2026).

Check for the garage

Ask the garage to check the gasket between the turbo and the cylinder head before replacing the turbo; if you smell exhaust gas, do not drive with the windows closed and have it checked soon.
