I have just purchased a 2004 330 CI. Very proud of it, and in excellent condition, but I'm a bit concerned about a strange noise coming from the dash after switch off. It sounds like it is coming from the fans, inside the car as opposed to it being outside in the engine bay. The noise is best described as being a loud whiring with intermittent clicking/ flapping. Any ideas? think it's something to do with the air conditioning, but wouldn't have the first idea ho to get behind the dash to check? is it a big job?
Any ideas most appreciated.
Also- minor point, but there seems to be a squeak coming from the rear parcel shelf or seats- any common faults that could provide a quick fix?
