This left side plastic what covers brake hoses and air pipes(and also sunroof front drain exit) has come loose just yesterday. Skidding on asphalt more/less and making a lot of noise. Removed the two clips but the inside part is missing on both(what should hold the plastic cover in place). They are specific clips/rivets(turn in/out and not pull/push and inside part has pattern). And is not possible to random ones in same size. Fortunately no other info on them than trw and 6.6 or 6.2.

When mine disintegrated on attempts for removal, I just used some cable ties to hold the cover up in place, wrapping them around the brake pipes and fixings. Not pretty, but did the job. .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember

I think the shield is LR part number SGC000011
The fastener is RYG000030 according to the LRParts.Ru website (HB1 in the picture) - but the number doesn't appear correct !

Yes, it is this HB1 part, but the oem number is not correct. There are three(maybe 4?) of them and there is thread inside. No idea how they plastic came over since they are large enough... And it's not two part item, just pattern inside of t30 torx to open/close them. Secured one with zip tie, broke the (plastic)thread of second and additional washer under third.
If I find them somehow I will replace them all if not then one more zip tie and done.
Thanks for the info guys

I took the long thin cover off the change the rusty brake pipe that goes over the rear subframe. I had to cut the plastic screws off and ended up fixing it back with roofing screws into the old plastic and penny washers. Do I really have time to tinker with one of these
