-Occasional whistle, rolling on closed throttle
« on: 12 November 2019, 10:50:57 »

2.5 petrol manual estate
I am hearing a quiet whistle occasionally, rolling along, in gear, closed throttle. The pitch is constant, braking does not affect it, opening the throttle stops it. For a while I thought it was not caused by my car, but I have heard it several times. I suspect an air leak on the induction idling system, but cannot find it. It does not do it with the car stationary.
