Hi i have 2 problems with my 2007 r320. The first one is once a month the air suspension pump fuse blows and the air in the front suspension drains out and lowers the front end on the floor with aa warning saying car too low. What could cause this to happen.

secondly

after 24hs of not using the car the battery is dead and have to jump start it which is really annoying but can not get my head around it to find out what is causing this to happen. Also in the boot theres à black box on the right hand side that clicks every few seconds. Could this be the problem ? Other that that the car drives brilliantly with no problem while running. Any help would much appreciated.
thanks in advance
theres no error codes at all

You need to figure out why the pump fuse blew.
(Likely, bad pump / internal short, or pump relay flaking).

Fix this, the power supply to the air suspension is a big power draw, but should be very occasional.
It doesn't turn off when the car goes to sleep after parking.
If you can, park the car on flat even pavement or garage concrete so the suspension rests level and even.
Otherwise it will lose a little air, and adjust by adding,.. over and over until battery is flat.
