So some of my front lights were acting weird so I resoldered my lkm, and now my coolant level light and brake light circuit light went out, but now when I turn the car on it says check control. But as soon as I start moving, check control turns off until I turn the car off then on again on. Is this normal? 94 525i

Maybe you knocked about the CCM (Check Control Module) right next to the LKM. Pull it out, swab the contacts with an alcohol soaked q-tip, and put it back in to see where you stand. FWIW, I pulled mine, and opened it up to see if I should give it any attention. All looks very low power, and is covered in a protective varnish. So I concluded there wasn't anything to be done inside mine. Just saying, I'd bet on it's connection before failure first.
