Hi
I have replaced my Compressor Pulley with a new one my part dealer sold me for my 08 535ix.
my belt was destroyed 3 times last 3 month.
So far as I can see the pulley is the problem. It does not stand in line with the others.
can someone help me with the correct one I need?
I come from germany - this car was never sold with this engine there. Obviously nobody can help me here.
Thank you!

 

Are you sure it's not the crank pulley that's wrong.

 

Hi
I'm not absolutely sure. Why you ask for the crank pulley?
Is this a known problem? How can I diagnose it? Or what happen with the crank pulley when its defect?
Thanks for your feedback.

 

Is your belt ran on the crank pulley? Do you see any issue with your compressor pulley or figure that's the issue since the belt runs the compressor. I have only seen crank pulleys go bad but I'm not there looking at your issue so you're going to have to figure out which pulley it is. Visual check is not hard, and you should see what has the issue. Is it wobbly, is the pulley intact with no breaks. That's it.
