idrive mystery

When I turn on the 6, the idrive screen will work sometimes but other times it will flash on and off like its trying to boot up but won't. I thought it might be the battery being that it was 4 years old so I replaced it . Its still doing the same thing. Also, when I unlock the car using the keyfob, it will not work unless you press the lock button first.

Is this fuse related, keyfob battery related or do I have bigger and more expensive problems??

I believe the keyfob charges when its in the ignition. I have not opened it up to check and see if the battery is soldered or not.

Thank you for your help.

Some tasks:
- Check fuses
- Check battery voltage with engine on and off (any multimeter should do the job)
- Check for your bluetooth functionality (a bad TCU can cause similar stuff)
- Check your DVD drive and remove any discs inside and try again
- Reset your iDrive
- Do a hard reset (battery 20 mins disconnected)

Are there any patterns for the problem? Like when turning a corner, hard braking, high/cold temperatures, bumps?

If you have comfort accesss the ley fob has a replaceable battery (CR2036).

If you do not have CA you have a rechargable battery in the fob that charges in the igntion. It should last you the life of the car.

I would say it will "almost" last the life of the car. My battery is starting to go on my non-comfort-access key. I need to be within 10 feet of the car for it to unlock. I think I will eventually need to break open the key and replace the battery (key halves are glued so it's a bit of a hassle to open).

Car battery was replaced 3 days ago. It was disconnected about 20 mins when replaced. The screen was malfunctioning before I replaced the battery. The car is 9 years old with 136k on her. I misplaced the 2nd key fob about 3 years ago so I have been using the same keyfob during that time. All the connections are tight. Sometimes the screen will come on when starting but when I turn the car off and on again it will not.

I will replace fuse #64 and see if that works.

Could it be the voltage regulator??

Somewhere on here I thought I read it could be a bad, dirty, or scratched Nav DVD. Try pulling that and see what happens.

I haven't found the problem yet. I will try changing the fuse today and see if that works.

idrive mystery

It also can be the CCC which is also called the Car Communication Computer, can be going. Had the same problem when I own a 2005 645ci, idrive will work at random times until one day it wouldn't come back on. Also on my 2009 650i had almost the same problem as my 2005, but will turn off and restart. BMW under warranty replace in this order CCC, CCC indash dvd drive, and finally they found it was the amp overheating. This picture was from my 2009 650i after the idrive would not come back on.

Do you even need that system? Can you just put in an after market stereo that uses screen for video?

Hey Vegas can you ask your Indy where he got the CCC module? I called the dealer ship and it was a $1000 just for the part.

yep. I just called BMW las vegas and they sell for $1050. When I called my indy they said they would have to get the unit through BMW. They must get a discount. I see one on ebay for 640 free shipping. Not sure if its worth the savings if it goes bad. $950 installed doesn't sound too bad. Desert Oasis European Auto service is the name of the indy here in Vegas. Its located next to Las Vegas BMW. I might shoot the ebay guy an offer of $500 and see what happens. You can youtube BMW ccc and it will show you how to get the part out. It looks simple.

Definately need a good indy when you own one of these cars!! I am getting the front pads and rotors replaced tommorrow from a guy that comes to your house and does it for $120. Parts were $319 through Meyers. Indy quoted $700. $260 savings not bad.

The CCC install isn't that hard to do. You just have to go slow and not nick any trim. For my 05 645ci BMW did a goodwill fix on my CCC and I believe the whole cost was right around $2,000. BMW replaced my CCC with a refurbished unit. You can use a CCC from an 5 Series (E60) as they are the same as the 6 series.
