High pitched whistle


New member
Hi folks, I have a 2015 SWB/high roof. Took it up to Brissy and back (~100k each way) yesterday, and noticed an intermittent whistle that each time lasted about 20 seconds, probably 10-15 mins apart. Sounded to me like it was coming from the rear of the vehicle. We were doing 100 kmh at the time on cruise control. Weren’t braking, so couldn’t be that. Anyone else noticed anything similar?
