Late reply but for others to see. I have a 2011 Mini. It has 20,000kms on the clock so still new. Ive been driving it around a lot lately and parked it for 2 days. It seems to run rough on cold starts after a few days with a small puff of blue smoke then it runs fine. Then all of a sudden after being parked for the two days it would not for the life of me start! Just kept turning over and over it really wanted to start but honestly sounded like it had no fuel. I heard the pump working, the relays and fuses are all fine. The closest MINI from me is 120kms. After the second day I stormed into the garage with both key fobs. Sat inside the car, using the 2nd fob I locked then unlocked the car a few times (checking to see if the key battery was still good) and inserted the fob. I didnt try to start it but the car said the fob was going flat. I removed it then tried the main fob but I decided to remove the silver cover. Maybe thinking the metal was interfering with the communication to the ignition. It started!!!! Ran a little rough, blue smoke puff but the idle wasnt too bad. I took it for a spin. Ran normal, no signs of anything. Parked it, started it again with no hassles. I hate cars with computers!! I miss the days of carbys and open engine bays!
I will still take her to MINI, get them to check it over. Fuel pressures, immobilizer, ECU. I dont trust it right now!
