Electrical problems with the BMW X5 Diesel 2011: Flickering lights and weak battery
(Translated from German)
Summary of the thread
The 2011 BMW X5 Diesel is experiencing electrical issues, including flickering lights and a weak battery. The owner suspects problems with terminal 30. A similar issue was resolved in a BMW X3 by replacing the battery and fixing a disconnect on terminal 30. It's suggested that the owner take the car to a mechanic for a thorough check. Other potential causes of the problem could be a defective cable, plug connection, screw connection, fuse, or control unit. The mechanic should also check the alternator and battery, and look for misfires in the fault memory.

Hey, thanks for the reply! Interesting to hear that you had the same problems with your BMW X3. So everything points to terminal 30. I'll probably have to make another trip to the garage then. Can you remember approximately how much the repair cost? And have there been any incidents since then, or is everything running smoothly again now?

Hey, exactly, these were pretty much the same problems I had with my X3. After I took the car to the mechanic, they fixed the disconnect on terminal 30 and I haven't had any problems since. Everything is running great now, no more hiccups! The repair cost me €960 because the alternator wasn't charging properly, but I think it was worth it. You rarely see vehicles with problems like this these days, so I think it was worth it in the long run. So don't worry, just take it to the garage and they'll sort it out!

Many thanks for the information! That reassures me a little, even if €960 is a hefty sum. But what won't you do for your car, right? So off to the garage. Hopefully everything will go smoothly and without any further complications. I'll let you know when the car is running again. Thanks again and see you then!

Hello, what does the break in terminal 30 mean? Screw? Plug? Can you fix it yourself? What can cause the interruption? Regards LL

Hey Leo, in itself, the interruption can mean anything, i.e. a defective cable, a defective plug connection, a defective screw connection, a defective fuse or even a defective control unit which does not switch the voltage through. In this case, you would generally have far more fault memory entries if the control unit is defective. You can of course rectify this yourself by measuring the voltage with a multimeter. If the voltage is not present on the corresponding cable, the cable must be traced back until a defect can be determined.

Hello everyone, doesn't it help to re-learn the battery? Had one in another older BMW vehicle (11 years). Could still drive it a bit. I changed the battery in the X3 myself and taught it in with a Carly adapter. Cost me €279 (original battery from BMW). Regards Leo

Hey, I drive a 2014 BMW X3 and recently had similar issues. Last time at the shop they checked the alternator and battery and ended up replacing the battery. She said that the electrical issues could be from a bad battery. She also checked the fault memory for misfires as that could also be a cause. So it could really be terminal 30. As soon as the battery was replaced, the problems were gone. That was a bit annoying because I wouldn't have thought that a battery could cause such serious problems. Best to take the car to a mechanic and have him check it out. Good luck!
