Hi everyone. I am a new owner of a 01 S4. Changing the oil today I saw a sensor of some sort on the drivers side front suspension that was hanging off. I reattached it with now it is driving me nuts as to what it could be for. It ataches to the lower control arm, and it is only on the drivers side. It senses the geometry of the suspension for something, but not sure what. ESP maybe?


Thanks for any help.
