2006 Mercedes-Benz R350 Q&A
2006 Mercedes-Benz R350 Question: why has my car dropped low?
Sounds like you have an issue with the airmatic suspension. Are you getting a service suspension message? You may have an inoperative air compressor; circuit issue (could even be a blown fuse)? You need to take it to a repair facility that is familiar with the system and have it checked. - brinkline
