Sorry, I can't provide any more details :( I put up the info as it shows on the worksheet so that it would hopefully be able to help someone.

I think the CID is the display but we would need Weasel or someone else to interpret exactly what I wrote. I don't know what a "PUMA case" is (maybe a case that goes to BMW NA?) or a "LVDS cable" either...

Puma is a case that goes to BMW...

mine is out for good
 

First time it went out was 10/22/09. Has been going out with increasing frequency over the last couple of months, but the re-booting process always brought it back up. Not so anymore (went out yesterday afternoon for good). Nothing helps/works. Goes to dealer Monday AM.

Could it be a problem with the ambient light sensor. The manual says the Nav screen adjusts to ambient light, at all times. You can adjust the brightness, but it still compensates on its own.

I wonder where that sensor is and if you cover it, will the screen still stay dark?

I have an 08 4.8 and this exact phenomina occurred to me for the first time 2 days ago. I wil have to keep an eye on it. I shut the engine off, gave it a few seconds, and restarted the screen came back up.

Any update on this problem (i.e. display going dark)? This happened to me while driving our 2008 4.8 X5 a few months ago and I reported it on the next service visit but they could not verify the problem. The display went dark yesterday while my wife was driving the X5 and again the screen was normal the next time the engine was started.

I already have an appointment to go in this Friday but my original warranty has maybe 6 months left. I hope if there is a problem with the screen that it will be fixed now.

Also, is there a thread somewhere about things one has reviewed before the original warranty expires?

Sorry I should've updated. The issue was fixed after they replaced the screen. They have to verify the issue though, which is the biggest thing, so you have to have your camcorder/phone ready to record every time you start the car. If you have the same issue as I did, where the idrive is still working while the screen is dark, shine a flashlight on it and show it's still working otherwise. Show the brightness setting is all the way up. Compare it to the bright lights on the dash, etc. Record all of this.

After a month of daily attempts, I finally caught it happening. Show this video to your service advisor and he will mark it as a verified issue - at least that's what mine did. If you send me $19.95, I will send you my video to save you the trouble. I'm kidding. ;)

As for a checklist for outgoing warranty, that would be a good idea but I don't recall ever seeing one here. One thing is I would have them check your rotors/brake pads since that's a hefty job covered under maintenance. I got my pads done but not rotors since apparently they were still above minimum spec. New wiper blades won't hurt either. They should also be doing the 32(?)-point inspection & oil/filter for the annual as you near your 4-year mark anyway. I just had my factory warranty expire 4 days ago actually... but I extended via 3rd party. I didn't extend maintenance.

Helpful response, thanks much rh71.

My wife drives the 2008 every day so I will not have a chance to make a video. I have taken videos to the dealer before and the results have been mixed.

If this is not resolved on Friday then it will show up as twice reported. In the meantime, I will try to be on alert when I drive the 2008 on the weekends.

^ have her take a pic with her camera phone perhaps? Or drive it straight to the dealer when it happens (swap cars with your wife?) and leave the ignition on for them to verify. Can't imagine they would deny you then.

Where the heck did you learn this??? Some more crazy secret button codes...
