Just made an appt to bring in my 08 MINI S for the 3rd time. When it's hot and a/c is on there is a high pitched squealing sound in the area of the water pump. I don't know why they can't fix it! Perhaps its the belt? Supposedly they replaced the whole thing last visit. Has this happened to anybody else? Thank you.

 

taking it in next week for the 4th time... not really liking my MINI S too much right now.

 

Mine had high pitched sound, i left it, went away and never came back after a month or so

 

for my first post, then.

mine had the same thing and i sprayed it with crc belt conditioner

it went away, so far for week, and i hope stays away

hope it works for you

 

sounds like a glazed belt. water pumps generally dont squeal like a stuck pig.
