X5 e53 battery drain???

[friedman]

Thanks. It's such an annoying Gremlin. I'm on my third new battery in two months. Thank Walmart for their free 3 year exchange policy. My first parasitic draw problem came from water in the trunk. I found the problem in the rear pano-roof drains, and I zip tied the hoses by the two drains. Unfortunately my ibus, and Amp were under water. The short also took out my LCM. A sign of the ibus broken is turn signals or lights work outside and not on the instrument cluster. Other signs of LCM problems I believe is hazards, high beams, door locks, and turn signals. My high beams had stopped working. Make sure you get the right LCM, theres one with Halogen and one without. Buying the right one and it supercedes your old one is fine, that's what I did. Look at RealOem.com, for reference. Make sure you put in your production month. You need a $80 programmer so a dot doesn't show by your tripodometer. I do not know if it would set off a TMU at inspection. I did not want to take a chance. There are YouTube vids on it. It has taught me a lot about troubleshooting and building my confidence.. This last draw is a real Beach! I suggest anyone reading this with similar problems to get a amp clamp with readout on bottom as well for parasitic draw diagnosing and a decent $150ish smart x5 e53 reader. They say 16 minutes for our truck to fall asleep, but I suggest 30. If you see water on the back right there will be water on the back left as well. I hope I helped at least one person from getting ripped off from a stealership or repair shop. My first parasitic draw I had 10 years ago, a shop charged me an arm and a leg to diagnose a bad stock radio head.
