Finished washing my car this afternoon and when I started it up to move it back on the drive it made a Big Bang noise and then a really bad knocking. At closer inspection it looks like the pulley is knackered on the air con pump.
Tried to take a picture but it's not very obvious.

The cars whined a lot since I bought it just over a year ago and someone once told me it was the air con pump.

Has anyone had this before? Is it possible to change the bearing/pulley or is it a new pump job?

Does anyone know the part number for air con pump off a cls55? Does it have to be a 55 one or do other model pumps fit?
 


It's the one at the bottom, it doesn't look right and when the engines on it doesn't spin balanced and it sounds like the knocking noise is coming from there
