Battery Swap Now Windows and Turn Signals Do Not Work
 

As the title says, windows and turn signals do not work. I did not have a battery tender for the swap. I do not have an IBS (battery sensor) so I figured I could reset. The fuses for the windows are okay, I even checked them with a meter. Tried disconnecting the ground wire for two hours. Still no change. Any thoughts? I would like to avoid the dealer if possible. Thanks.

Any chance your interior lighting also isn't working?

Did not notice in the daytime but the interior lights are not working.

Ah, sounds like your Footwell Module has died. It's a fairly common issue. Mini did extend the warranty on affected modules to 125k miles so I'd recommend calling up your nearest dealer and seeing if you're covered. I've been holding off doing any coding on mine as it looks like it has an issue with the boot sector as well.

Basically the issue is that on the eeprom chip on the board there's a boot sector that fails, which is the first part that's read when the unit is powered on. The rest of the chip seems to be fine, so as long as it's left on no worries. But if you completely power cycle, reset for coding, disconnect the battery or if the battery goes dead it fails to boot due to the bad sector.

Same thing happened to my 2011 mini, "footwell module" went bad. Replaced under extended warranty.

We see footwell modules die all the time when disconnecting the battery.

Call your local dealer and give them your vin as there has been an extended warranty on them just for this reason so maybe you'll get lucky.

The dealer replaced the footwell module under warrenty, BUT I was told that because I did not buy a BMW battery, if the footwell module goes again BMW will not cover the module under warranty. A new module costs $735 (Can). These cars are sensitive. Thanks for the help.
