Mersaydeez

i have a 2000 mercedes s500 w220 my car was making a loud noise like air was being released from the front right side. it sounded like it coming from the bumper when i luckily made it home and shut the car off it was still making that noise even with no power so i disconnected the battery left it alone for 2 days and when i put the battery back in the car raised and the noise is gone now im not sure if its a glitch in its system or if i should get new struts? i let it get to operating temperatures and drove it around my neighborhood car stayed up havent seen that message at all after driving for 15 minutes
