Please help...if you can 02 X5
 

I was driving home today, the X seems OK. After stopping by my sister house and park the X uphill. When i came out and drove home, On Board computer doesnt work, no information from cluster work, speedo, gas, thermo, everything does not work. ABS light is on. I tried to access OBC from the MID, nothing work. The car drive perfect. Any suggestion?

check the battery, could be on the way out, not holding a full charge.

And one more thing, the clock change back 1 hour along with all other things above. This drives me crazy, I cant see how fast I am driving with down speedo working.

sounds like battery to me

Has anyone have this problem before? And what is you fix? I doubt it is the battery since all other things work including stereo, lights, alarms. Looking at the cluster display now, all needles points way left, and OBC functions on both cluster display and MID doesnt work. ABS light is on. One thing was weird is the clock change back exact 1 hour as this occured. I will pay visit to the dealer first thing in the morning. Do you think disconnecting battery and reconnecting it may help? I need to figure this out tonigh. Fairfax Dealer is an expensive place to visit.

I could recommend you to a local independent mechanic who may be able to help you, but first please tell me, are those just typos or are you not a native English speaker?

How did the car start, as normal or very weak ?
I just think that the battery doesn't go bad in a second, it usually gives signs well in advance, and as you mentioned that stereos etc. worked fine.
I quess that the cluster has broken or maybe a fuse has burnt in it.

The car starts strong, drives strong. Interior lights are brights, stereo is ok. But the instrument cluster needles are not working. On-Board Computer is not displaying anything. ABS light stays on. Orange backlights are bright. Do you know what burnt fuse could cause this? Thanks

Check the condition of the battery..it's easy. Seems like you're avoiding the most likely problem in search of a more complex one.

NOVAX5: The stereo plays, the int. lights turn up and it starts right up and runs strong? It ain't the battery.......hell, these guys might as well tell you to check the air in your tires cuz it ain't the battery. If you don't know your way around the X (checking fuses and such), take it to a reputable independent mech. or bite the bullet and visit the dealer.......

Bad or weak batteries on the X5 cause all sorts of weird things to happen. While it certainly could be some other problem, the battery is a cheap and easy thing to check first, especially since you have an '02 with what is no doubt an original 4 or 5 year old battery at the end of its service life.

If thats not it, check fuses and whatever else is suggested by the other posters here.

Also try disconnecting the battery for about an hour and let the car sit. That often works wonders.

Sometimes BMWs, like little kids, just need a time out. :rofl:

Batteries can power many accessories as well as start the car and still cause issues with the electronics. When you start the car you put a huge amperage load on the the battery and it's likely not recovering as quickly as newer battery would. Granted it's not the only thing that could cause this, but it's the first on the list to check IMO.

Well, today I had my local mech check the fuses. All fuses intact. He also ran a battery check, battery good. So he couldn't seem to find anything to fix. I called my fav. BMW shop in Alexandria, yall in VA should know who it is. He said the Unit in Dash need to be reprogrammed at dealer as it went bad and produced a glitch in the unit, he also told me that a common issue that happens to BMWs including his M3. Only dealer has the computer and software to do this. So tomorrow morning I will be at Fairfax and ask for it. I will let yall know how it goes and why i happens. So next time if anyone has this problem they would know the fix.

The problem turns out to be WEAK BATTERY CAUSES GLITCH in SEVERAL MODULES to shut down. FFax BMW gave me a brand new 07 325 for 4 hours to drive around and replaced the battery, reflashed the modules, reset the computer. In the end when I left the dealer I think I dropped 3 bens somewhere around the dealership and couldn't find it in my wallet, STRANGE...

I wouldn't go to your sister's house anymore, that's the problem.
Just kidding with you, like everyone else says, check the batt!! how old is it? Try to charge it if there isn't enough volts in it. If it doesn't hold the charge, it's time to replace it.

Weak battery it is then..

Though illogical, I agree with the other guys, start with the battery. Mine went around the same time as yours, no weird issues, but given the timing it seems like the best choice especially since you'll probably need to change it soon regardless.
