A simple oil change became a major pain thanks to almost all of the under tray bolts destroying themselves when trying to take them out.
I've got less than half them holding back in,but it's secure enough. I think I'll go get a full new set of those bolts and clips, that should be good for another few years.

They don't really last too well - I always coat the bolts with copper grease but they stil give problems. My solution was to cut out a section of under tray beneath the drain plug and then fix a removable flap so oil can be drained easily. I used the type of fasteners that you push or pull the center on to remove and the flap was made from my wifes old flexible plastic cutting board thing. Cost minimal and it is exactly like used to be fitted on my old XantiaProgress?
