My 2006 miniCooper won't start, justs rapid clicking noises

Sounds like the battery does not have a full charge. If it's the original battery, get a new one and have the alternator checked out while you're under there.

You could have a bad cell. Take the battery in for a charge and load test.

take neg turminal off while running. if it stays running it is not alt. then go to autozone get batt check.....for free

What was the fix? I am betting on a new battery as I experienced the same thing. The MINI battery will just up and die with little warning I remember a fun night of driving home with a car that would die mid corner due to low RPM's as a result of pressing the clutch in.

Bad answers from badmac. NEVER remove the cable on a modern computerized car, and in my professional opinion stay the hell out of auto zone unless you want to buy some washer fluid. Have your battery professionally "load tested" by a certified mechanic, it"s usually free. If you can see the needle your bat. has to hold 2.5 volts under a load. If not, junk it. I strongly suggest buying a battery, brand name " Interstate" it will give you years of trouble free service. Mini seems to have a good alternator, mines a 2005 S and I've had no problem with that yet, over 100,000 miles. The o.e bat went after two years, being sealed whereas you cant add water it ran dry and blew up in it's rear compartment, no damage, just a loud bang. I replaced it with an Interstate and have had no problems.And Yes I am a real mechanic.

So SORRY thats 10 volts under a load, I was thinking something else. If that needle drops the slightest bit under 10 v that battery is trash. In most cases you'll see it drop like a rock, but still under 10 is junk.

Before you do any of above,do this:- turn engine off and remove key fob. Grab hold of steering wheel and jerk it firmly to left until stops on the lock then repeat to the right. This sets the steering lock electronically. Re insert key fob, put clutch to floor and start engine. This works 99 out of 100. Advise every time you turn off engine do the left /right move until stop, and don't panic (got this from mini owner/ mechanic) don't understand why this isn't in hand book!

I have the same problem of clicking, after leave the car under the sun (just under the sun) New Agm interstate battery, registered with the scanner, I need to unconnect the negative pole and in a few hours starts normally, I have months with these problem a and few batteries
