Hi everyone! I'm a new member and I'm very excited that this forum exists. It seems to be a wonderful resource with lots of great participants.

I just picked up our 08 SLK 350 yesterday and I already have a question for anyone that might be able to help:

There is a sound coming from the driver seat, but it isn't constant. At some points when there is any pressure into the seat back (just a bit like the little pressure of being pushed into the seat while accelerating) it makes a sound. I don't know how to describe the sound. It is like a rattle or a buzz, but neither of those words seem accurate.

I was thinking it might be related to the lumbar as if some air is being pushed out of it. I've tried to recreate the sound with lumbar turned completely up and completely down, but neither seems to tell me anything. Sometimes it does it and sometimes it doesn't. It is definitely related to pressure on the seat back. If I lean away from the seat when it happens, the sound stops. If I push back into the seat, it starts again.

The sounds seems to be coming out pretty close to ear level, making it very annoying.

I'm taking the car back in next week for some work, but I figured I'd see if anyone here knows what might be going on. I don't know if the passenger side does this. There has only been a passenger in it for about 5 minutes of driving.

Until I get this fixed (whatever it is), I'll just have to crank up the music.

Thanks!
