    My car has below symptoms, all of which related to voltage issue that caused engine to cut down while driving on motorway at 50mph. Here is the video. Symptomps are as below; (1) When the car is parked (gear at P), and the key is inserted and brake applied in order to start the car, after...

    Hello. I hope I’m posting this in the right place. I bought 2012 x3 in March. The dealership put new coils on before I took it home. Replaced the alternator and battery due to the battery not charging. Purchased the alternator from FCP. About a week later it started getting high voltage. Only...

    Dont replace your alternator before you watch this video

  5. F80/F82/F83 M3 and M4 (2015 - Current)
    :dunno: Hi All, So my lithium battery has gone into protection mode of some sort or open where it protects the battery from over charging or draining below 2 volts or so. The battery was out of usage for more than 8 months. So I think now the battery must be at 0 voltage. The lithium charger...

    Hey everyone, I'm new here and would like to get an idea as to when I should replace my battery. Currently, I have a voltage reader in the cigarette lighter and I've been noticing upon startup the voltage that it reads out is 11.1 volts. The question(s) I have are: 1. What voltage should my...

    Hello, A little help needed. I searched for an appropriate thread but didn't find. Anyway, last weekend, about 100km from home, my battery light came on. I used the OBD check test No. 9 to get a live voltage readout and it was showing around 11.5V. Turned everything off and drove home and just...

  9. E60 / E61 (2004 - 2010)
    So I've had little electrical issues for a long while but they're growing and I'm at a loss. I know very little about electrical DIY so I'm in need of serious help. I've taken it to my local indy. His made it clear that there was something drawing the voltage down. He said it was most likely...

    Coolant level is fine yet I get the coolant level warning on the dash. Replaced the sensor but still get the warning. Checked the voltage coming through the connector - it's only about 8.5 volts, so that seems odd. Has anyone done troubleshooting on this system or have ideas on what to check...
  11. X5 E70 (2007 - 2013)
    My X5d - 2011MY, June 2010 build, ~112,000 miles . . . O2 sensor was last replaced 5 years/~78,000 miles ago, Trying to eliminate weak O2 sensor as the cause for a 20% drop in fuel mileage. There are no CEL/MILs . . . trying to determine if O2 sensor is weak, but not weak enough to trip a...
  12. E60 / E61 (2004 - 2010)
    At the moment my 545i is dead in the driveway with zero sign of life. Zero, as in the batterey may as well be missing. I walked outside and unlocked the car like any other day and it flashed the markers and made the chirp. I hop in and all the lights turned on like normal, and before i could...
  13. X5 E53 (1999 - 2006)
    I'm stumped! This past weekend I drove my X5 about 100miles, turned off the car, a minute later got back in, drove another 30 miles, and shut down the car. As I was shutting it down, I noticed it took a while for the windows to roll back up. Seemed strange, but I was in a rush so I ignored it...
  14. E90/E91/E92/E93 (2006 - 2013)
    Hi Guys, I've been doing a lot of reading of previous post and getting a ton of conflicting information. I just need this spelled out to me as clearly as you guys can provide. Here is my dilemma... My battery is not holding its charge and I'm getting the "Increased Battery Discharge" warning...

    Here we go....2005 X5 I've been trying to get rid of the triad of lights for some time now. I removed the transfer case actuator, found the gear worn and replaced. Re-installed actuator and the lights did not go away. Vehicle started and ran fine....just the dash lit up like a Christmas...
  18. E60 / E61 (2004 - 2010)
    Hello, during the last month I've been getting this annoying alert every morning that says that there has been an unusual voltage drop due to a higher than expected consumption since last turned off the vehicle. From what I've learned about my 2010 550i h, it has a sensor that measures the...
  19. 7 Series - E65 / E66 (2002 - 2008)
    I have 2006 BMW 750 LI, the car would not start in the morning, the battery was completely dead. I took it to the dealer and after 4 days they decided the Car Access System (CAS) is the problem and it needs to be changed. After I changed it (Cost around $1300, first the dealer asked for $1670)...
