Hi, I'm new here!
I have a Mini one, 51 plate..
Recently i took it to a garage because i heard a squealing coming from the drivers side under the bonnet.. Turns out its a belt (not sure what belt though?!) If you open the bonnet it's the belt that is the drivers side and you can see quite clearly.. Anyway, with the engine on he said i needed a new belt and this should fix the problem. However, he didn't even check the belt whilst the engine was off and in my view the belt doesn't even look damaged?!
If it helps.. The noise stops after the engine is warmed up and right now the temperature is quite cold and we've had a lot of rain.
(I'm a girl and have no idea what im talking about btw)
