Dear S owners,

Anyone experience the pisst sound coming from front engine bay? Esp after cutting off engine or when car idling... Sound like front airmatic... Airmatic just change few months back... Suspension pump change last month... Mine is w221 pre facelift

My first relationship is with a Japanese. Raw n pure. Then I move on for a Korea born American. Quiet n demure. I broke off with her for a China bitch. She so eye catching but her emotions is crazy. I decided to let go. Went for pure Korean then. The feeling was good. Realized she is too small for my size. I quit Korea and got myself a huge American mother fxxker. She so loud n powerful. She seems couldn't have enough of my ramming. Always asking for more. I felt like a king. But maintenance is crazy. Meanwhile I had a affair with another even bigger Amercian. The feeling was good. Get to choose riding who each day. Finally I'm tired. One day I decided I think I wanna try a German and I got her. This is the best one ever. Sleek... Quiet... Ready to charge anytime... I promise I will be faithful this time round and ride on her and on her only. Her name is Mercedes-Benz....

Yup, that from the airmatic releasing the excess air pressure from the system to do its leveling. And its normal..

its actually from the airmatic pump, the airmatic pump usually pump very high pressure air pump thus making that pissing sound

The world Most dangerous thing is the Vehicle. Its not about the machine weather its slow or fast. Its the person who is controlling it. The driver is the brain of the Machine. Not the machine itself.

If the driver reacts slow even the most powerful ABS(Auto braking system) will not help. The driver has to give the car the command in Order for the car to react. Afterall he is the brain of the car.
