I have a mini cooper converatble 2005 chilli pack series I am experiencing leakage when I put the windows up and down - especially when raining getting in and out there appears to large drips coming in - is this normal

Put the window down & look into the inside of the door with a small
light & use a wire to unlock or open the door

Then remove the inner door panel & fix the problem

I found solution. In my case problem was with connection next to the small electronic module next to the gear wheel. It is module directing red light in proper 'P', 'R', 'N' and 'D' letter.

I cannot specifically answer what the washer is for, but washers are utilized when tightening the screw or bolt and space needs to be filled, especially to obtain a tighter torque, but if the screw/bolt threads down tight and fine, and with the correct torque, then you should be okay. On another note, there is a headlight recall for 2005 MINI's. You can find the number to call and details at automotive.com Here is another source for recalls being developed and issues to possibly expect:

sounds like the flat tire monitor warning, the button is by the handbrake you should check your tire pressure,

I have got the same problem on my Cooper S. It was happening around Christmas time, I did'nt think much about it at first until I went to my car on Boxing day to find the inside soaking wet from the rain where my windows had dropped again. I have called the AA out aswell as going to down to the Mini Garage.I got told by the AA that they think that water as been getting into the fuse box under the bonit. I hope this helps.

IF IT HAPPENS AGAIN POP THE DOOR PANEL WITH THE BACK OF YOUR FIST A COUPLE TIMES THAN TRY THE WINDOW AGAIN. IF IT WORKS HEAD TO THE DEALER FOR A NEW WINDOW REGULATOR

drivers door latch is bad there is a module that is part of it and its not responding

Clear out the drain tube. May be able to do it with a coat hanger, or get someone to blow it out with some shop air.

often times this problem ends up needing a front sunroof section of the conv top replaced. The cable that drives the hooks to unlatch is most likely broken and that is currently the only fix. EXPENSIVE. Sorry
