Started the car this morning, then ran back inside to grab something, came back 2 minutes later and the instrument cluster stopped working. Car still idling perfect, just none of the gauges work. The digital display doesn't work either, so I can't check anything with the hidden obd menu.
I checked fuses 10, 34 and 43 and even though they were still good, I replaced them anyway, but it still didn't fix my problem. After Googling around I came across this advice:
I followed the steps above but didn't hear any changes, and my instrument didn't come back on either. Then I unplugged for the negative terminal on the battery for 2 hours to see if that fixed anything, which it didn't. At this point I'm pissed, so I roll up the windows. The windows go up an inch, then stops. I press the button again, and it goes up an inch and then stops. To get the window up required pressing the button a bunch of times. So obviously there is an electrical problem going on, hopefully I have 1 problem that fixes the windows and the instrument cluster.
Last week my voltage regulator went out. I didn't order a new alternator since it seemed to be working, just the voltage regulator. Last Monday I installed the voltage regulator and bought a new battery while I was at it. I'm pretty confident I put the ground wire on the back of the alternator correctly. Car ran great until this morning when the instrument cluster died on me. The car still starts, haven't tried driving around in it since the instrument cluster is now off.
Any ideas on what to do? Could it be a bad ignition switch (was planning on swapping soon anyway)? Could it be a bad alternator (doubtful, but thought I'd ask)?
One thing I have read a lot about is making sure the ground wires are nice, clean, and secure. Can anyone give me a list of the ground wires with their locations so I can pull them off off, clean then, and rescuer them? I don't know electrical stuff very well. I know what a fuse is, that's about it.
Right now I am unplugging the negative battery cable for the whole night, and will see tomorrow if that fixes anything. Then tomorrow I'm gonna remove the instrument cluster itself (2 torx bolts, unplug the connectors and then replug them in in case there is a loose connection or something. After this point I am completely lost on what to do, the only clue I have is that the windows seemed to have issues all of a sudden too. I suspect whatever is causing the windows to shudder like that is also responsible for my instrument cluster.
Any idea on what to do?? I have literally spent $3k on replacement parts in the past couple months to get my car nice and reliable, so I'm trying to do everything I can to avoid a new instrument cluster from BMW for $1k+. All the posts I've read from 2010 said around $1k, and I just know that 2014 the price will be more like $1,500. Help!

Quote:
1. Turn off the car. 2. Remove fuse 10, 34, 43 3. Start your car back on. 4. Turn it off again. 5. Put in all the fuses, turn on again and see if it works. 6. If not, turn on the car, remove fuse 43 and note response and functionality. 7. Do the same for fuse 34. 8. If my guess is correct fuse 10 disables the entire cluster. If its a firmware state problem the above should help, if its a hardware related problem then it won't. |
