Side Bolsters Deflating

[Iyzmi]

I have my side bolsters pumped up all the way and have noticed that after about a week they lose a bit of air. They don't completely deflate, but if I hold the button down I am able to get a noticeable amount of extra air into the bladders to get them back up to max pressure. Is it normal to have to re-inflate the bolsters regularly to the max amount?

Part if my OCD to not leave them fully pumped up so no...

i would say this is not normal and you likely have a leak. i'm not sure exactly how they work, but if the bolsters are in fact inflated with air, i would imagine they would get worn out over time. being inflated at max plus the car's interior getting warm when its parked on a hot day has got to take its toll on the seals or valves.

Yeah, I'm thinking I may have a very slow leak. It looses air so slowly that I would probably have to leave it at the dealership for like a week for them to even diagnose it so I'll probably just hold off for now. I will just monitor it to get a better idea of how long it takes before it drops some pressure. I've noticed it really doesn't deflate past like 80-90%. Just doesn't seem to hold that last little bit after a while.
