Hi
I have a 2002 x5 3.0 petrol (with LPG also), recently it's developed a strange noise. It started as a metallic type chattering a few weeks ago but we picked it up from the airport after 10 days away and it seemed a bit worse, this morning it progressed to a knock? type noise, it was bad so i took a video and left the car on the drive!
Not sure if its possible a failed pulley could make this noise? The alternator was replaced a couple of months ago.

If anyone has any ideas please let me know.
Thanks
