Has anyone ever experienced vibration in their seats? Above 70 mph, I feel an annoying vibration in my seat but no shimmy in the steering wheel. I put my hand on the top of passenger seat and I can feel it quite a bit. I have a very very minor curb scratch on one of my front wheels but I can't believe that would be the root cause. Checked all wheel tire pressures, all ok. This is a '14 S4, 3K miles and I've never hit a pot hole. Just curious on other's experience, maybe this is normal?

Did you get the Magic Fingers seat option when you ordered? It activates when you put quarters in the coin slot on the console.

Seriously, no vibrations for me but when I get a different feel on various road surfaces, I always think something went out of whack. It certainly could be a bent wheel but you would probably know if you hit something hard enough to cause it.

No vibration, but the seat on my current S4 has a little FRONT/ BACK movement to it that I did not have in my 2010 or 2014. I know this has been discussed before. Anyone have a quick fix?

Quick guess would be bent driveshaft but that would be pretty hard to do.

Remove wheels, check rear tires for broken cords/bubbles and have the wheels rebalanced.

Yup that did the trick! The car spent 1/2 day at the dealer yesterday. They unmounted every tire from the wheels and Road Force balanced them by re-positioning on the wheels. I can't detect any vibration now. Service rep told me there is a TSB for Pirelli Summer tires. I was also told the vibration could come back if I rotate the wheels.
