Does my ABC Susp. use any Air Pressure or all hydrolic? Hearing a "ssss" sound const
I've had my "ABC Visit Workshop" (no red) Light flash on a couple of times, took it to my Dealer guy who just looked at it, raised the car and lowered it, then put some extra Hydrolic Fluid and said it probably just noticed low Fluid and everything should be fine. It briefly popped on and went off after turning the car off recently.
I notice a constant "Sssss" or "hiss" sound coming from *what seems* like my Suspension, I thought maybe it was my motor, cats, a regular airy sound coming from elsewhere, but now am thinking it may be the Suspension. Is this normal, does an ABC Car even use air pumps??
Also, how high do I need my ABC Fluid Tank to be, should it be all the way to the top.
Any help would be soooo appreciated, I'm kinda freaking about it.
Thanks.

ABC is all hydraulic. The tank should be filled to the fill line, not the top. Mine has a dipstick. It should be filled to the notch. The hiss is probably not the suspension. You should have it checked though. It could be the vacuum line that operates your doors and seat pneumatics, if you have them. Or something else.

You might have dipstick with notches on both sides:
MOTOR AN - UNBELADEN - engine turned on , no load in car - the other side: MOTOR AUS - UNBELADEN - engine turned off - no load in car. Make certain, not to overfill the tank. The leak will scare you....it scared me...

They didn't run any codes, the guy just basically put Fluid in and sent me on my way saying that it was probably just a little glitch or noticed something was low, since the warning came on for just a second (both times)
Thanks for the level info, I'm gonna go check right now.
Also, here's a Video I took of the sound, it's really hard to hear with all the other air noises, but the best way I can describe the sounds is it sounds exactly like when you're letting air out of your tires, and when I turn the car off it winds down normally. You can slightly make that sound out on the Video I think, it sounds like it's coming from around the front wheels.
