Aluminium undertray

[Simon 3.2M]

I'm looking to swap out my engine mounts and I'll need to remove the tray. Are the bolts single use only or can I reuse them?

I'm sure many have been reused but are listed as single use with torque + angle to fasten. They're £2ish from BMW.

Also note, when jacking the engine, don't panic like I did as the car rises too... it's just the springs unloading

They are single use, but it's uncommon even for BMW techs to replace them. Personally I reuse them a few times before I replace them.
