X5 engine noise
 

Hi friends, the engine of my x5 2002 3.0i is making a strange noise, like a huge air leak or vacuum, no check engine, rpm are normal, here is a video.https://youtu.be/8dZQaqUqIag

Have you connected it to OBD? I would say VANOS kicked in ja :D

What about the Vanos??

Vanos is probably messed up

The noise gone, i found the disa valve was broken, i change it
