2009 SL550 Bubbling sound from ABC reservoir with car off?
My 2009 SL550 just recently started having problems that seem to indicate the damper is bad, but while checking it I also noticed the hydraulic fluid was low so decided to fill that up first, after I filled it up I noticed I could hear bubbling noises coming from the reservoir even though the car had been off for over 30 minutes at least and I still hear them, any idea what the bubbling noise is?
