HELP With a8 air strut valve plug
 

HELP! I hit a pothole and since the suspension hasnt been good... I took off the wheel and found out that the plug/valve has popped out! PLease can I replace it with something or a new one? Or do i have to buy a whole new strut? I dont mind having the car at permanent lift mode as the streets in Brooklyn are JACKED!

Please see image.. TIA
