Ok, I figured I would update. My electrician friend came by today. Right off the bad, he said the relays that our cars have are garbage and need to be replaced to either a Seimans or Hella brand. Then it turned out that one of the relays, the "supposed K70" according to his diagrams, not the Bentley manual, which is the one closest to the tail light, was sticking and causing the issues. He had a Seimans relay that he plugged in and right away, everything went back to normal. So problem solved, and I guess I have to return all the stuff that I purchased for no reason.
Now, that same relay, also controls the air suspension. Which leads me to believe that quite a few people seeing problems with their air, should also replace. I am going to see if ECSTuning has all of the relays, and replace all of them. The ones we have in there are just shitty, and according to him, he always sees them fail, always.
It was odd that it was the first thing he said when he saw my car, and fixed the issues in literally 2 minutes. So thumbs up for another free fix.
P.S. He tested the relay as soon as he removed it, and it functioned fine. As a matter of fact, he plugged it back in just for shits, and everything worked. He still threw that shit out because according to him, it is just not worth the risk. He also said that these relays are in the American BMWs. Not the ones made in Germany.
