Before I sell my 1.4 mk3 to my boyfriend (hopefully), I'm going to sort out the little niggly problems first.

Over the past week, there has been a strange noise coming from the left side of the car. It only happens when the engine is cold and after driving for about a minute - the noise stops. It's cross between a hissing and a tapping sound and the noise gets louder and faster the more I accelerate, to me it sounds like something in the engine bay is catching - possibly the fan?? I have no idea.

Any ideas on what this could be?

My second issue is the passenger door. Ever since I got the car, every passenger has had trouble opening the door! Now, it won't open at all from the outside and I have to lean across once Im in to open it! Ive been told it's just a pin that needs replacing so I know these problems I need to fix aren't major, they're just annoying. Anyone know how I fix the door? And how much everything will cost all together?
