Does sound that something may be either leaking or not pumping? When it goes up- does it stay up?
How long should it take for the airmatic system to raise the car? (W220)
Takes at least 5 mins on mine (maybe longer) and been told my pump is on its way out.
My Sclass takes about 5 seconds from switch activation to full height.
I was at auction today and there were two S500's, neither of their pumps were working properly... must be a common issue...
I've just had the pump replaced. Whilst the airmatic was rising and falling at the right speed it sounded like an angle grinder whilst doing it. It's party trick was running for 15 minutes after the car had stopped which was particularly appreciated by the neighbours at midnight the other day.
Normally a leak would take a few days to be noticable. If a leak is present its either a strut or the valve block. Ive never timed mine, but Ill have a look im sure its not as fast as 5sec.
I'm sure I read that you've had big problems with your airmatic in the past.
A stealer has told me that the pump is on its way out. They say that the original pumps are mounted with metal rivets and they start to rust, causing a break in the seal and hence a leak.
Apparently the replacement pumps use plastic rivets and so they don't rust. Will cost about 350 all in to replace.
Ive had lots of problem with the car, the suspension issues were more to do with ball joints and bushes. Get it to a dealer and providing your car has a full history it might be worth asking them about a goodwill claim, it seems the w220 suffers from this and they might make a contribution.
It is fine to leave the car raised for an indefinite period. I suggest you raise the car on a flat surface and take accurate measurements - the best would be to actually place objects (e.g. a cardboard box) next to each wheel and mark on the object the exact position of the wheelarch brow. I suggest this approach because it is not possible to take accurate measuments simply using a tape measure.
Leave the car for a minimum of a day but preferably longer. Observe any drop at any of the four corners. A drop indicates a leaky strut or valve block.
If there is no drop, use the objects to check that the car is being raised and lowered correctly on Sport II setting through to "raised". Each corner should drop 15mm for Sport II and rise 25mm for "raised" - though check your handbook for your figures.
Really, it should take no more than 30 seconds to go from Sport II to raised.
I did successfully recondition my BMW air pump - they are easy to take apart. I just drilled out the rivets and replaced with self-tapping screws. A motor engineer will be able to re-wire or re-bush it for less than £150 so there is a saving to be made by re-furbishing it yourself.

Sorry, I should have said: I have an E Class. In the E, the sport II setting drops the car by 15mm even at rest. The "raise" button lifts the car by 25mm.
If the S-Class system is different, just check the handbook and make sure your car lifts and drops as it is supposed to.
I am guessing that the pump is a pretty standard design across all the cas - including BMW. Certainly, my MB pump looksvery similar to the BMW pump in my E39.
The lift and drop times are also fairly similar between the two makes so I don't see why the S-class shouldn't riase and drop just like an E Class or a BMW 5 Series.
