Suspension suddenly taking time to pump

When I turn on my car, it says to wait for a few minutes before the suspensions are aired enough to drive. Sometimes this doesn't happen, other times it can take up to 10 minutes for it to pump up.
I have taken it to the usual autoshop and 2 days later they cant find any problems with the suspensions.

I was wondering if anyone had experiences similar problems with their suspensions and if so, how they resolved it. I would appreciate any help! Let me know if there is any other information I can provide for a better diagnosis.

2012 CLS 500 Blue efficiency

Hey, thanks for the reply. Ive already taken it to a garage and they couldnt find any leaks.

I had a look at the first document on there, do you think I can do those steps at home or does it take specialized equipment?

Certainly, involves spraying locations specified with soapy water. If you find no leaks, garage claims all was checked properly including no fault codes (i.e.: compressor), and they did not check filter & relay proactively try this.

Hey,

Thanks alot this was super helpful. I've organized the information for my garage.

The problem with it is it happens sometimes and not other times. Like sometimes overnight the front left suspension completely falls and the car is on the tyre, other nights it wont happen for days at a time.

Thanks again for the detailed reply.
