After Jumpstart, Onboard CPU & Gauges Dead

[deanblue9]

I agree. However, road side assistance did came with the trickle charger to jump start my car and I did have the same problems as described in my previous post.

Isn't there a jumpstart procedure? I can't recall exactly, but isn't there something about cranking up the heater to full blast before disconnecting cables?

Maybe someone can offer us a refresher?

Well, after taking it to the dealer, they had to replace the instrument panel/cluster. In fact, they had to do it twice, because after the first replacement, I heard a strange ticking/humming sound when the car was at idle. In my case, I'm not sure if the bad instrument cluster was the cause of the electrical problem (and the dead battery), or the result of the jump start. Regardless, I'm glad the car was CPO, since it would have been expensive to fix. If the car needs a jump start again, based on my experience and others who've posted, I'm not sure what the best approach is!

I had the exact same issue on the same X5 (ie 2004 4.4) and need only to replace the #43 fuse to correct the situation and restore the instrument cluster gadgets that were out, tach, fuel guage, etc.

I am having exactly the same issue! My battery was dead which is odd because the battery is only 4 weeks old. I did let the X sit for a few weeks but I thought with a new battery in mild weather it would not be an isse. I am thinking I have a short.

I jump started the X and now the gauges don't work and I cannot get my Navigation out of 'German'... ??? I went into the setup and tried to change to USA but it did nothing....

I am going to check fuse #43 as mentioned. If that does not work I will do a battery disconnect and reset.

Any other ideas???

Had this same problem after jumping a dead battery. After removing/installing the instrument cluster fuses (1,43,45 - not sure which one did it) all is well again.

Had the same problem, my battery was dead and I gave it a jump start, all my Onboard and speed needles were dead......i tried resetting the fuses 1, 43, 45 and no help......I disconnected the ground cable from battery for 30min. and that took care of the problem.......I love this forum.

holy cow, looks like i will be getting a new battery asap so as not to risk getting stranded and needing a jump start....off topic slightly but anyone know off hand if any fuses need to be removed before disconnecting old battery terminals?

Tach, gas gauge were dead after a jump and climate control had gone to centigrade. I drove 25 miles this way with no change. I then removed the 3 fuses (1,43 & 45) and checked, none blown. Reinserted the fuses and all is now normal. I'm elated but a little puzzled. The best theory that I can come up with is a computer was affected by the low voltage but would not "reset" until fuses were removed (0 volts) and replaced (spec voltage). - Cheers and may your fix be as simple.
