  1. X6 E71 / E72 (2008 - 2014)
    I recently replaced my battery from my E71 X6M with a new one because it was 9 years old & rapidly discharging when the car was locked, but the other day I went to start up my car with the new battery and on the iDrive it said battery discharge & I checked the Volts & it had dropped below 12...
  2. E60 / E61 (2004 - 2010)
    Hello I am hoping that someone else has had this problem with their e60, So I've been having battery discharge issues and replaced the alternator, bought agm battery, replaced a relay that was throwing a code, and bought an rdc module since it was missing. Now it is reading codes A85F, 2E8E...

    Recently I have been having a parasitic draw on my battery. It kept dying over night and I was unplugging the negative terminal a few times since I needed the car in the morning. Then I noticed It seems to be only happening when I lock the doors, If i leave it unlocked while its parked its fine...
  4. BMW i3 I01 (2014 - 2020)
    Well I've had my 2017 BEV almost exactly 2 years now and love it. I never worried too much about the airbag recall, being neither I nor my partner are females under 5'2" and 110 pounds or whatever the details were that prompted the recall. But I recently moved to Vista (near San Diego) and after...
  5. 7 Series - E38 (1995 - 2001)
    I've had a transmission problem on my 2001 740i (topic for another thread) which has kept me from driving it for about 6 months. It's been in my garage. I had been starting it once or twice a month and letting it run so as to keep the battery from dying, but failed to do that over the past 3...
  6. X5 E70 (2007 - 2013)
    So here is another issue, that i can not resolve. "Increased battery discharge" I have been getting message every time i start my car after few hours being sit. At the beginning i thought its a battery, but the battery was tested and is still OK. From what i noticed vehicle is going to sleep...
  7. E90/E91/E92/E93 (2006 - 2013)
    I live in ohio where the temperatures have been reaching fairly cold at night (35f-15f). This winter will also be the first winter i drive the car (2008 335i sedan). I don't believe it has ever seen a winter before me either. That being said, for the first time a few days ago as i was leaving...
  8. X5 E53 (1999 - 2006)
    Right so after a week of trying to get my X5 to fire up its still dead on my drive, after being hooked up to every machine, autologic, snap on, launch X-431,bosch and a delphi I've finally decided that it's either a issue with the key or with the EWS all of the machines would or couldn't re sync...
  9. 7 Series - E38 (1995 - 2001)
    Hi All, Today I changed the bulb for the LED screen in the dash, and changed a brake light bulb and indicator bulb. I was driving along and all the lights (Dash, mirror) in the car started flashing/going dim, I managed to pull over and went to start it again to no avail. Jumpstarted it and...
  10. X1 E84 (2011 - 2015)
    First, I love auto-stop start so don't include me with the haters. BUT, here is a serious issue that I haven't seen discussed (perhaps because I missed it). When you pull into your driveway or any other parking spot, the auto stop start will stop the engine. If you make the mistake (as I have)...

  12. E46 (1999 - 2006)
    Right.. Ive been having this problem for a while and havent come to a conclusion yet.. And the reason me posting here is im hoping one of you out there can help me and put my mind back to peace. Right, so i used to start off with a dead car battery on random occasions when the car has been left...
  13. X3 F25 (2011 - 2017)
    I have a concern. I live in a condo with no ability to plug in a battery charger in the parking garage. I will be going away for two months. What is the downside of letting the battery go dead and using a booster to get the vehicle started when I get back home? I have been cautioned that I...
  14. 7 Series - E65 / E66 (2002 - 2008)
    Hi All, Yes, another thread on battery draining and modules which may be waking the vehicle up, causing low voltage. I have read everything I could find the past few days to try and get some knowledge from this forum and others and via Google. However, I have not determined a clear path to...
  15. E90/E91/E92/E93 (2006 - 2013)
    I have an 08 328xi sedan which was hit in the front passenger corner. Both the wheel bag and passenger roof bag deployed. The explosive charge on the battery terminal went off as well....(i believe its the BST cable)......Car starts if you jam the cable back into the terminal but the vehicle...
  16. E36/7 Z3 (1996-2002)
    Three times since I bought my 2000 Z3 2.8 Roadster in the last six months the battery charge has run down too low to start the car. Interior lights and dashboard come on, but there wasn't enough juice in the battery to start the car. The first couple of times I thought I might have left a door...
  17. General BMW Questions
    My 03 530i has a mystery battery drain. I'm clueless and mechanics can't find it. Does anyone have recommendations on who to go to for electrical help in the Phoenix area?
  18. E89 Z4 (2009 - current)
    I have a 2005 Z4 and it did not have any problems what so ever. I parked it in the parking and did not drive it for 2 days. Now when I tried to turn it on, there is electricity in the car and what I mean is that the lights turn on, the radio turns on, and I press the clutch but when I switch...
