im completely oblivious when it comes to cars especially my car haha i know its sad the only thing i know how to do on my car is change the tires, change the lights, and fill it up with gas haha please be specific if u tell me to do somethingEverytime my 99 528i bmw is in drive and at a stop it makes a weird noise?Change the idler and tensioner. The belt depends on how long ago it have being changed if ever. If you don't know then change the belt also. It's just $30.
See what happens after that. Hope your power steering pump is okay. Check the fluid level.
