Hiss on driver's side interior
I have a 2017 E400 wagon, with Premium Package 2 — so, the Active Multicontour Seats. The car is still under its CPO period.
On our road trip last week, I started hearing a hissing sound on the driver's side. I can't tell if it is coming from the seat or the door, or what exactly.
What could it be? The hissing starts... runs for 10-30 seconds... stops... then restarts a few seconds later. It will cycle like this for a few minutes then go away for awhile. After quite some time, it will all start over again. My guess is it's the active multi-contour seat but welcome thoughts.
