Greetings! And question
 

Hello all, this is weird being on a mini forum because I am a Mustang enthusiast but recently was given the opportunity to buy a 2003 R53 Mini S. I love the car, but it has become a project, so far we have replaced the supercharger, clutch, shifter, complete engine rebuild, and a number of body parts. I have decided to clean up the girl and give her some love, it has become a project car :/. But I love it. Everything is running smooth except for a few idiot lights on the dash that even my programmer ant figure out where it is coming from. My main 'problem' is a squeaking sound coming from one of the pulleys. This is driving me insane due to the fact that I have replaced the tensioner and then replaced it again when the problem wasn't fixed, we have a new water pump so it can be that, and we checked air conditioning and it doesn't seem to be coming from there. The supercharger pulley is stock size and belts are the right length. And the great thing is after the car has been driving for around 15 mins the squeak goes away. Anyone want to see if they can solve this puzzle?
Thanks guys, hope to see you on the forum soon,
Jack
