[What Have You Done To Your Car Today? Volume 2]

Treated battery tray rust due to leaking old battery. 

[Very odd squeaking noise from engine]

Hey all! I heard my sister start up her 320td yesterday morning and heard this racket, sounds like its coming from the front of the engine, any ideas?

I also know the viscous fan couping needs replacing, will be done when the thermostat is replaced soon.

Here's a video of the noise:

 

Any ideas welcome!
