I have a 2000 S500 and when my car is parked for extended hours, the whole car is down like a low rider. But when I start it, the car slowly goes back up and I can use it with no problem. Do you think the suspension is is broken or shall I just have it repaired with a strut repair kit. How much do you think this will cost me. I appreciate a concerned response. Thanks

 

Could be the airmatic compresser?
I changed mine when car was sitting to low.
You need a senior member to evaluate it
