Seem to be having a bit of a problem with my car, and maybe its nothing
but who am i to say, maybe you guys can be of assistance.

My car (VW Bora / Jetta) has started whistling when in reverse
any ideas what that could be?

Also there is a metal on metal noise from the undercarriage when
driving at lowrevs ie. upto 2500rpm from 1->3rd gear. The closes sound
i can get to it is basically banging to wrenches together.
Any Ideas?

regards,
