Condition |
There may be a concern with a rattle or flutter noise from the supercharger tensioner and belt. This occurs in V4 mode with light throttle conditions. Issue sounds like tick noise when in driver seat. This seems to vary between vehicles but replacing the tensioner won’t resolve the issue. |
|
Cause |
The supercharger belt tensioner will jump and cause the noise |
