car too low to drive 2004 MBZ SL500- 110,000 miles

Question by randy42 posted 10 months 2 weeks ago in SL-Class

my wife drove the car home with it way to low to drive. It is equally low on all four wheels.  when it drops equally on all four wheels does that mean the airmatic pump has gone bad. Is there a way to test it and be sure it is a bad pump and not a bad relay or fuse.  does it use hydraulic fluid, and could that be low.

what is the best place to buy the correct pump. there are several on Amazon, but none define for certain that it fits the 2004 MBZ SL6500.
