My car 2007 x5 4.8 recently looses clock settings and shows either left or rear brake lamps out. Even thou they were ok I replaced lamps and harnesses and keep resetting my clock. The dealer said that there is the problem with the battery and probably leakage. The engine usually starts momentarily. Please advice.
The dealer said to perform battery leak test and replace it for $800.00

And did that battery replacement fix the issue?

Honestly, I did not feel comfortable to spend so much money so far.

I feel that, thanks. Is the problem gone?

No, but usually my wife drives about 40-45 miles daily. Last weekend we went for the trip totalling app. 300 miles each way and so far the clock is OK, but I still get messages about rear brake lights malfunction and as I said I replaced bulbs and harnesses and both lights come on every single time when I apply the brakes.
Sorry for the description being so long.

You might need to consider replacement of the rear light assemblies due to these false faults
