Recently my car died while driving home and wouldn't start. So I did my research and replaced the crank position sensor. Well that didnt work do I dropped it off at my local shop to diagnose. Turned out to be one of the fuel pumps. Luckily a friend helped me out and gave me brand new pumps so I was only out a total of $400 for labor and diagnosing.
Pick up my car and its throwing three codes for Airmatic. Display shows message for it as well and of course it doesn't work at all. Car was low and gives bumpy ride but not super low like a blown strut. I then noticed my radio doesn't work. It powers up showing Mercedes symbol then goes blank.![Confused](https://mbworld.org/forums/images/smilies/confused.gif)
Now I did do something dumb when I first worked on my car so these issues are most likely my own fault. I started swapping relays and pulling every fuse thinking it was maybe just a fuel pump power issue. I pretty much swapped every relay under the hood that were the same and pulled every single fuse. I also pulled every fuse in the car and swapped the two relays in the right trunk. I did this with the battery connected and car off.
Yesterday I looked up the relays and fuses online since I dont have my sheet in car. I only swapped the Airmatic and air pump ones I could find. I pushed all the connected etc. Started car and voila it worked again
Well it was short lived and stopped when I restarted car 10 min later. This time car is stuck in the raised position.
Last issue was my IC pump seemed to be working erratically. One drive I was getting IATs sky high, pump wasnt running. Later after I messed with fuses etc again they stayed in the 55-60 range like normal.
What the hell did I do to the cars electrical ?!!
Frustrated. I shouldnt be touching my car, I seem to have the touch of death

what is your battery voltage?
try to disconnect the battery for a couple of mins to reset all electronics.

I dont know honestly. I know my mechanic had it on a charger.
I'll disconnect as you suggest and report back . What about the small battery ? Should I disconnect that too ? both are only a few months old.
Thank you

Disconnect for 10 min and same problems remain. I guess its good the airmatic is stuck high instead of low. Still no radio. I just dont know what I could have messed up so bad with the relays and fuses. Never had these issues at all until right after I did all that. Faulty relay perhaps ? Doesnt explain the command center going blank though.

FYI codes for airmatic are 5191 power supply valves short circuit to ground
5200 left front dampening solenoid open circuit
5500 critical level front axle (this one may be gone now since its stuck in high position)

My advise is take it to the local dealer. At mine , it would be 1 hr initial diag , unless things got crazy and couldn't figure it out in that time. Just explain what you did , and let a experienced tech go from there.

I dont think I have one anywhere near me. Could a good regular mechanic do the same ? There is a local BMW shop not sure about Mercedes. Been going to my GM guy who has 30 years experience and is really good.
