There are many awesome threads for DIY repairs, but photo bucket nuked them all with it's pay to have your pictured hosted as an embedded imaged scheme. Totally wiped out thousands of internet forums everywhere. I believe if you click on the pictures in question, it should lead you to the photo bucket account of the pictures, they just don't show up on the forum.
Suffice to say, I think the 7th gen tourer strut replace (or clean) isn't too bad of a job. Get yourself a plastic, trim removal tool off eBay for a few quid and start pulling away the trim around the boot opening, where the hinges are. I expect it's pretty self explanatory once you get in there as unlike an engine bay or dashboard, there shouldn't be a lot of other things and/or tech in that area. Just the struts and maybe a wiring loom for the rear lights. Might want a long plank or something to prop the boot lid open while you're removing the struts though. Worth trying a good clean/polish of the struts before committing to replacing though. As it might just be build up crud causing the issue, as opposed to them actually failing.
