Honestly... I don't think I will bother wasting my time.

I have asked for help, even posted precisely the same noise the car is making.

Unfortunately because the video happens to be a mustang I've upset some people.

If you think it's reasonable to start launching insults from behind your computer screen at someone who is seeking answers then wow.

Fair enough if you require a video of my XF then I will post one - but honestly I will not bother after how negative some forum members are acting as I don't want to be part of this community.
