New to the BMW world, might have bitten off more than I can chew, bought a 545i off auction, it was pretty obvious it had been sitting for a while, battery was trash but it charged enough to let me get the Solus on it, read the DME codes. Next day I put a battery in and lost connection to the ecu. Following day I still had no connection to the ecu, but I was piddling with things trying to get the connection to work, and the blower motor started, so I checked the solus and could access the DME, got the same codes as the first day, and it turned over but wouldn’t fire, I can access every module the Solis offers except the EKP, and the DME doesn’t recognize the IBS, but it’s the same plugged in and unplugged, included are the codes I get from the different modules

Also, I had heard about these cars and the water ingression, I checked the connectors on the modules and every thing was clean, the mdm connector was a little rusty but the module itself was clean. The solus also showed me the the terminal 15 wake up line has a .9v draw with the key off. It also tells me relay 1 is faulty

Take it to a mechanic and let him tell you what all it is and then choose if you want to fix it yourself or not.
