Clock & Trip Odometer keep clearing

Anyone have a solution to the clock going to zero along with the trip odometer? I don't beleive it's the battery. The other thing that happens is comfort access does not work or at least for unlocking the door, seems to be an intermittant thing.

I have not had a load test on the battery; however, I did charge the battery for ten hours to make sure it was topped off. Reset the time & date, used the rig for a couple of short trips for parts and when I went to put it in the garage last evening the time was no longer displayed. I will have a load test done this next week when I go into town. Just seems strange that there is enough power to start the vehicle but not enough for the other systems, and it does not struggle to start either. If these systems are so sensitive to power it makes you wonder why BMW would use such a marginal system?

Many many people wonder the same... I just know they do weird things as the batteries run low... Strangely the start, but trip other errors. Not saying it is definite, but the BMW battery will fool the usual 'logic tree' one uses...

GL, report back

Okay, just a quick update. Since topping the battery off to a full charge I have not had a reoccurance of this problem. I will still get a load test done on it as soon as life gets out of the way. It should be good given that it is only four years old - but it also seems that BMW undersized the charging system given the fact that it needs a specific amount of power to monitor or maintain it's systems. I'll be sure to let you know after the test.
