Hi all,

I'm new to Mini ownership (only picked up my car a week ago), I love the car to bits but it seems to have a couple of common electrical problems (presumably the PO couldn't fix or couldn't be bothered fix haha).

1) The drivers side window won't go up on the one touch, you have to hold it up but when it reaches to top, comes back down a bit? - really annoying!

2) I keep getting a message saying "Increased battery discharge" and the time/date settings keep getting wiped every time. I checked the battery and it seems to be at 12V but it seems to be able to go into this state over a few hours whilst it's parked up when I'm at work.

Has anyone had this? I'd love to get it sorted because it's a great car

Door window might need resetting, hold button down all the way once window reaches the bottom continue holding for 10 seconds, then the same going up and hold for 10 seconds, might work if not a dealer job
Battery winds like the end of its life, mine has been saying the same for a while now but date and time remain constant.

As above on the window front.

I think I'd swap out the battery... for the sake of £100, it rules it out. Make sure you buy an AGM battery with the exact same Ah rating as the one fitted, otherwise you'll have to have the car 're-coded'. I've heard people being quoted as much as £500 by dealers to replace a battery.

Thank you for the replies! I gave the window reset procedure a try, but it doesn't seem to have fixed it so I guess it's a dealer job. I might take it back to where I bought it from first though as I've only had it a week..

I'll try a new battery in that case, thank you for the warning, I've never heard of batteries needing coding to the car before!

-Independant dealer re-set the windows and it improved the issue .. still there every now but doesn't bother her that much

battery can be tested. the window can be alignment or a motor if a reset isn't working, but the discharge warning and clock, perhaps a software update is going to help, but I would guess the intelligent battery lead or leads may be suspect, as would cause both. Some cars need to be told the battery is changed, I don't think on this, but maybe, usually 5 series or up, some you have to enter the mileage at change, as the charging system adapts to an ageing battery, so if you don't tell it, the new one can be overcharged, something like that.

Charge the battery first, have it tested by someone not in business to sell batteries, go from there
