I have a 2006 Mini Cooper S, all of the lights inside and out just wont turn on. It's completely dead. I assumed it was the battery and replaced it yet the car is still completely dead. No crank, no lights on the dashboard. Just nothing. I have never had a problem like this one. What can it be? Things I will try... -Trace the positive cable from the rear to the front and make sure it's not damaged. -Check all grounds. -Check the main relay. Not familiar with Mini's, first time working on one. I really like this car and would really love to solve the problem. Any suggestions?
On the left side of the firewall under the bonnet is a plastic box marked Battery +. It contains the positive jump stud and that connection has been known to come loose causing what you describe. It also can become corroded. ....just sayin'
Till the experts get here I will try to help. But first a question. You said that you checked the positive cable for damage. Are you getting 12v at the engine bay?
Okay guys, well I got power in the car, it's great! But it wont start now, not even a crank. Last night when I was messing with it I accidentally dropped a 5 amp red fuse. It belongs in the spot where it has a check engine like symbol. The fuse closest to the bumper (hope it makes sense). Can that be the issue? Or might it need a jump start? Also keep in mind that it's 10 degrees out where I'm at. Not an expert when it comes to cold weather.
If your talking about the fuse box under the bonnet, then that is the ECM fuse. Did you replace it? it will not start with out it.
I'm talking about the fuse box in the engine compartment. I'm working on getting a fuse tester that way I can just check all of them. I'll keep you guys updated! I appreciate the help!
Boom, fixed it. First time messing with my Mini. Since I live in a place that snows a lot (Ft. Drum, NY) I guess somehow the positive wire connectors became extremely corroded causing the vehicle to receive no power whatsoever. I cleaned everything in the vehicle that connects to both positive and negative, including the started connection. Boom, their it was, the car came back to life. Don't do what I did and spend a lot of money on a new battery, check all connections first.lol. Thanks to everyone who helped me out! I love this page!
tjo20 Glad you got it squared away. Don't feel bad about buying a battery. Your 2006 was overdue for one.
