I am a new owner of a 2003 Golf TDI. I have been going over the car and I too was changing my oil and notice several bolts loose on both axles. Is this a common occurrence?

Slightly overtighten or remove, clean out all the grease in the threads on both side, and use some medium threadlocker...and overtighten slightly. You won't be happy if the axles come loose while you're driving.

Spray brake cleaner through the threads (if it's pressed in well so none gets into the grease) or use a paper towel or q-tip to at least get some of it off.
