Hi guys just a question as I don't know much about BMWs I've been trying to figure out what's going on with my car first the battery seemed old and dead so I replace that started up fine but when it sits couple days The battery dies like something is still running doing research online I came across the couple ideas to check one being the IBM sensor so I unplugged that that did not help next thing I was reading about was if you're TPM sensor has corrosion it could cause the battery to drain inside the vehicle when started that flat tire indicator comes on and stays on while driving I'm not too sure just looking for ideas where to start next or where I could find the TPM or the FTM and if his could cause the battery drain. Also says in vehicle after jump start high battery drain
