My C36 started making this noise from the belt that sounds very familiar to the noise of krikets at night. Its a loud squeqing noise and it happens when the car just sits there as well as when i drive it. But as soon as i spray this belt spray on one of the pulleys it goes away then comes back. What can it be from?

Sounds like the belt needs replacing ASAP. Check the condition of the tensioner and shock while you're at it. They usually wear out every 4-5 years. Might be time for a belt and tensioner and shock.

i went through one belt already, and that didnt help

Did you change the tensioner and shock? Sounds like that's your problem then.

Can you adjust the belt tension on the M104? I thought the tensioner does the job automatically, and then you replace it when it fails.
