Hi All,
So I have the dreaded battery drain problem. 2014 Crossroad. All good until last week, then suddenly wouldn't start. Enough power to power locks, display, etc. but not enough to turn the engine over. Jump started fine.
Took it into the dealer, who didn't listen to a word I said about BCM, etc. After arguing if I should pay a diagnostic fee under warranty, they finally just replaced the battery. 2 days later, new battery dead.
The battery takes a charge to 100%, and if I disconnect it, holds that charge. I have wired a Noco indicator connector, and the battery drains around 25% every 24hrs.
Of course this happens when we have a 5000km road trip planned starting in 4 days! We do not have time to leave the car in the shop for 4 days for them to re-create the issue.
I have searched the forum and found lots of information for diagnosis and talk of TBNs, but none actually list the specific TBN for re-flashing the BCM... Does anyone have this?
Looks like I may have to go buy a small booster pack to stop us getting stranded in the middle of nowhere
