Hey everyone, this is my first post on here, my car is giving me some issues that I cannot seem to resolve. It randomly started stalling while in gear about a week ago, like to the point I have to put my car in neutral any time I stop in traffic or it dies, and no it’s not the auto start/stop I have that permanently disabled.. the real odd part of it is, it only does it in forward gears, I can put it in reverse and hold my foot on the brake all day and it never dies, I put it in drive, and it’ll die in less than 10 seconds. It’s got me baffled. It isn’t like a stumble and then die, it just shuts off and then my car gives me all the “you’re not in park” warnings… anyone ever have anything like this happen? Car is a 2012 535i xdrive cat-less down pipe, stock resonator, no mufflers, intake, fmic, mhd stage 2+ tune, xHP stage 3, x-delete,
