CONDITION SUMMARY:
Situation: A noise coming from the underneath of the vehicle may be evident. The noise is most prominent during
light throttle and low speed, for example during car park maneuvers and is independent of ambient temperature
range. Under these conditions, a low-level non-constant cyclical-type noise can be heard coming from the Center
Exhaust system (Exhaust Valve) adjacent to the fuel tank.
Cause: This may be caused by a contact noise that is being emitted by the interaction of the first two gears internal
to the exhaust valve located on the Center Exhaust Pipe assembly.
Action: In the event of a customer concern of the above, follow the Service Instruction below.
