High pitched whistling sound

[pshoe]

I’ve been hearing a high pitched whistling sound from the left front air bag area of my 2015 DS. It doesn’t happen all the time and goes away if I do a manual dump then air back up. It’s not a fast leak as the compressor has no problem keeping up. Has anyone experienced this? I suspect it could be the ride height valve.


Thanks - Phil

I had an air line leak on the left side - not quite a high pitched whistle. Turned the front tires all the way to the right lock position and took a spray bottle of soapy water underneath. DO NOT have anyone activate the airbags or leveling system while doing this.

The leak was quickly apparent - our local Freightliner shop fixed it in about 30 minutes by re-cutting the end of the line and reinserting in the valve.

Have you read your FL owners manual. The manual would should that a Ride Height Control valve is in that area.
