  1. 7 Series - E65 / E66 (2002 - 2008)
    Hi everyone, I went through the list but couldn't find my issue. I have a 2003 745i that I cannot get INPA to connect to. It starts and runs fine and I can get a cheap $20 code machine to pull fault codes and clear them through the obd2 port. For some reason though the more advanced...
  2. E36 (1991 - 1999)
    Hi all. Picked up a used BMW from a buddy. 128k miles. He bought it off an estate and it's sat for 4 years. Seems like a good little car but have some weird things going on - unsure if they're related: 1) driving with A/C on. Occassionally it will shut off, the controller will go dim and...
  3. X5 E70 (2007 - 2013)
    Hello Gurus! We own a transmission shop and primarily only work on domestic cars. Customer brought in a 2011 X5 so we took it to a specialist who said we needed to replace the transmission. Customer didn't want to pay for it so we offered him some cash for the car and he took it. We thought...
  4. E90/E91/E92/E93 (2006 - 2013)
    NAV screen comes on then goes dark multiple times for 5-15 minutes after starting my 2006 330i. Then it comes on. All things normal from then on. I have tried rebooting and disconnecting/reconnecting the battery. Anything else I can try before bringing it in and probably replacing the...

    hi, I have a battery drain. I have found the fuses that are causing the problem and removed them to stop the drain but cant figure out the problem. both of these need to be removed to stop the drain. R3 RELAY IN THE BACK (audio unit relay) and FUSE 72. (1st in line, the audio/nav fuse)...

    Is it possible to convert the OBD computer in my 1986 325e so that it will function like OBD2?
  7. X3 E83 (2004 - 2010)
    So I know there is a secret menu for the on-board computer, but I don't know how to access it or what all it does. I've searched around and cannot find the specific answer I'm looking for. Is there a way to change the "Average MPH" to "Current MPH" to use as a digital speedometer? As a bonus...

    Hello All, I am new here so first I wanted introduce myself and say hello to everybody. My name is Adrian and I am a fresh owner of a BMW Z4 35i (2010). Since I bought the car I am experiencing some weird behaviour: 1) Sometimes (1 in 60) the car won't unlock using the remote key - I need to...
  9. X3 F25 (2011 - 2017)
    My trip computer screen on the main display stopped showing info, it is just blanked out...it shows "---" for all the categories. Also, the clock on the main display shows the same "---". The same info from the trip computer is available by switching through the small display behind the steering...
  10. E46 (1999 - 2006)
    Hey All, Long time BMW owner, first time poster. Title says most of it. I went away for Christmas break for 3 weeks and came back to find my computer (with the mileage, temp, etc.) blank (light still on, but blank). The car still works fine so I think nothing of it. Fast forward 2 days and I...
  11. E46 (1999 - 2006)
    I bought a BMW 328i from a guy who purchased the car from an auction. The car did not come with a key from the auction. So the guy I bought it from, purchased a BMW key but he never had the key coded to the car. Therefore, I can not start the car. The car's engine had almost everything taken...
  12. E36/7 Z3 (1996-2002)
    I have a '99 Z3 2.3, and my battery will run down over the course of about 2 weeks. To trouble shoot this problem, I first determined that the total draw on the battery was around 237 milliamps. I then checked individual circuits by measuring the current across the fuse sockets. It happens...
  13. E39 (1997 - 2003)
    hello all, I have a '98 540i and we just hit 310,000 miles. I say we because we hae got to know each other very well.. She's a great old girl and I still love driving her, had her since 2003. However, for a while now she occasionally cuts out, just for a second, while under way. It...
  14. E90/E91/E92/E93 (2006 - 2013)
    So it's been almost 10 months without a radio in my 2007 328xi. I went in to get a part replaced that was recalled.Apparently the battery cable from the battery to the fuse panel burned out and essentially shut off all electrical power to my car. so I called the tow truck and they brought it to...

    I have a younger brother (20 yr old) driving around in a 2009 BMW 125i Coupe. Its white, with black interior, automatic transmission, low miles. Its a pretty cool car to look at. My brother on the other hand, is a whimsical college student, taking care of virtually nothing but his grades. He's a...

    Hi, I'm new to the forum so please excuse anything I do wroung. I recently just got a 1984 BMW 318i and after charging the battery, it worked--for a while. I couldn't go above 1st gear until I found that the gas pedal cable was loose. I fixed that and it revs high. The owner before said that it...

  18. X3 E83 (2004 - 2010)
    Hello everyone, this is my first posting as is probably not uncommon, I have a problem. I have a 2004, 154,000 miles. This is a strange problem, because it seemed that more than one system failed it once, or at least very close in time. I was several hundred miles away from home (doesn't it...
  19. E60 / E61 (2004 - 2010)
    My 2005 BMW 535d seems to be having power issues. While driving the computer fails... I loose all systems... Auto trans, steering, brakes, tire monitor, GPS etc. Sometimes all the lights flash. I need to pull over and restart the car so computer reboots. Until it happens again. Can't drive fast...
