I have a 2003 s600. Yesterday while getting into my vehicle and starting it I felt my car lower. I then drove it up the street and began to smell something burning (fluid). I pulled over and looked under the car and found that it was leaking hydraulic fluid from the front driver side.. is this a high pressure hose?

 

My s600 has the Abc suspension

 

There a few ABC hoses that are around the front and under the engine. There were recalls on certain hoses some years back. Have they been completed on your car? If you've been to the an MB dealer in the past few years it probably already done. A lot of time I see the ABC hose in front of the engine close to the cooling fan and radiator get small pinhole leaks. It throws ABC fluid on the engine belt and then the belt comes off. The fluid is expensive too. good luck.
