Question about 2004 Mini Cooper

1 Answer

2004 mini cooper doesn't start

Went to my car this morning, did not leave lights on or anything so I know it's not the battery, I did put the key in the ignition and run back into the house for 2 mins and left the door open. The "dinging sound" indicating the key is in ignition was going when I left. But when i got in and turned the key everything went dead, no turn over sound from the engine, no lights would go on. Absolutely dead...I had to run to work so I jumped in with my wife and caught a ride with her but in thinking about it, would that be a security feature of some sort that shuts everything down like that?

Most likely a bad battery or battery terminal connection.

SOURCE: engine fan won't turn off

That's a good one. Follow the cable. Most of the cases is under the hood near cabin wall.

The dial should come up slowly to just a hair above the center point. This should happen within the first few minutes of driving.

Hello and welcome to FixYa!

As a first course of action, please check if you have fuel. It can be the reason why it won't start. If fuel is good then the problem can be on the fuel pump. If the fuel pump is faulty, it won't sip fuel from the tank going to the engine. A humming sound on the engine will indicate that the fuel pump is working, if you don't hear anything then the fuel pump must be replaced.

Hope this helps and thank you for using FixYa! Have a good one!

Whats mean the code B2AAA for 2009 Mini cooper s Thansk

it means this P0420, make appointment for service, should come out like this code but if you out of service do this remove BCM (Body control module), PCM, ECM tcm FUSEs, waited 30 mins, the reconnect them and put battery back on, or if you don't want to do that take the battery off, then go inside the car and turn the ignition on and the lights and anything ells you can turn on. they won't work but they will drain the voltage stored in them, leave like this for 15-40 min and then reconnect the battery should be back to normal. but turn every thing off again before putting the battery back on.

My 2005 mini cooper went in for minor service basically an oil change (everything else running perfectly) and now it won't start - mechanic asked for spare key and that didn't work.

Why did your mechanic used his computer (notebook) for resetting service warning? It can be reset by holding the trip button and turn the ignition on, then release at reset message, then press again trip, until the message flashes and then release and press short again.

You can try to reset BCM by disconnecting battery leads, leave it one hour, then reconnect, turn the ignition, without starting the car, wait one minute, then start the car.

2004 mini cooper key fob not working

Open the FOB and replace the battery. The two halves of the fob come apart and there is a battery that you can replace.

Car started fine and now doesn't. The battery seems to be fine (new). No error code. Any suggestions?

Try removing the Neg battery terminal for about 30sec. This will effectively (re-set) the main computer to default factory specs. It worked on my 2004!! Also might have an ODB2 code reader run by you local auto parts dealer. They can get the codes too.
Have fun,
