A while ago I had experienced some knocking sounds from the front of the engine. Turns out one of the bolts for the power steering pump had worked itself loose and ended up in the undertray!
Luckily the belt didnt shred and leave me with a huge mess to clean up! As I went to reinstall, one of the bolts ended up snapping on me. This is probably because the pump was loose and putting additional stress on the remaining bolts. I ended up using some temporary bolts I had on hand and ordering new ones.
The new bolts arrived and installed them last night, this time with loctite. This appears to be a common issue with the N54 power steering bolts. I beleive the bolts will tend to back out if the bolts are removed and reinstalled, even if they are torqued to spec.
