Hello. Thanks for the pics. Box looks good. Internally and externally. Which is really good because it's still intact. Wait for the replacement compressor to arrive and it will arrive with it's own black compressor relay. It will not be green. When you reconnect everything, make sure the battery is disconnected, for obvious reasons. At that point, at the end, reconnect the battery, and cycle the car and let it start. The rest should be automatic. Clean and spray a little WD40 onto your level sensors, on to the arms. FYI, if your ordered the valve box for the airlines, DON'T replace the original brass fittings at the end of the lines. The original should be still good. Don't over tighten, just enough.

In my case, it was the box that failed and I had to replace the compressor, valve box, and front struts on the vehicle. GL.

How did y'all find a replacement fuse box? None of the used ones I found on ebay are a direct replacement for my vehicle. Looks the same from the top, but the pins are configured a little different here and there on the bottom.

Is this the original Mercedes part I'm looking for?

Hello. Do a search by part# and then try searching by make and model, engine type... People that post may omit some details here and there, but in your case, you want to make sure all pins are connected. Don't just leave a pin here and a pin there - I'm joking of course :) ...

Try this website, www.car-part.com, you can search by a few different parameters and it should help you out. GL.

Just an update I ordered a new arnott air compressor through FCP Euro. I also found an OEM fuse box from Mercedes-Benz brand new at $225. I put everything together and the bags filled with air finally. Then I test drove the car and after about a hundred yards I heard a loud pop in my right rear so I'm assuming the airbag blew. And by now I'm so frustrated I'm just going to bring the car to the dealer and have them fix it. Lol. And then I'm going to sell it and buy a new pickup truck. I really do appreciate everyone's help especially Pete!

Hello. Frustration is just a bonus 😉 for owning a MB, and the work that goes into it. Find a local Indy shop and you'll save a dollar or two. Then, decide if you want to sell the car.

Honestly, change both bags in the rear and you'll be good to go for a while. Don't let one airbag ruin your outlook on life - jk, lololol - there's brighter days ahead, for sure. If you got too much money and just want to throw it away at the dealership, then you can make a one time donation payment of $99.95 to 'Pete's Hookers & Blow' fund... Lmfao 🤣...

Joking aside, you're welcome, and GL.

Happy Holidays!
