R350 Suspension went flat, blew a fuse - PeachParts Mercedes-Benz Forum

Yesterday I noticed that my wife's 07 r350 was sitting really low in the back. I got in it and started it up and it never pumped up. So, I started looking at the air bags and they looked fine and realized the pump was not working. I looked at the fuse box and one of the 40A fuses was blown. I ran to the parts store and replaced the fuse and it pumped up just fine.
Question, is this a sign that something is going wrong or was this just a fluke? Any comments are appreciated and I don't think any warranty work was done on the airmatic system.

Most likely that is the first sign of a failing pump.

Great, I figured that might be the case. I'll let you know when it goes.

It already has. If you don't fix it now you risk damaging other components.

Really? I have to admit that I am still learning about the Airmatic system, but I need to go ahead and replace the pump after a blown fuse? What other components could be damaged if I don't get it replaced?
I am starting to question wheather I should have purchased an R-class. I don't think this was Mercedes best effort at quality. I wonder why they did not go with the pneumatic system like they have been using for the last 40 years. They should have asked Land Rover or Ford if air suspension was a good idea.

my 2007 R350 is leaning towards the passenger side
I'm going to a Foreign Auto Tech mechanic, I don't wanna get taking advantage of/overcharged.
So,
to my knowledge I needa have my fuse(s) replaced being as they've never been replaced.
Once that's done and if my R350 passengerSide-air suspension doesn't rise,
then I'll proceed to further troubleshoot other possible malfunctions.

How many fuses did you need to purchase and how much were they. And how much would you estimate labor costs to replace the fuses?
