Here is an update on the current position. I still could not get my VMware based manual to operate, turns out to be I believe a hooky copy and the producers have been able to identify it online and disable it, which would account for the specific instructions that came with it for installing. So I invested in yet another manual, infact I got the Mk2 and the Mk3 versions for the same money, bargain. Pages are perfectly scanned, the old one I always suspected were scans done from scans, not so this time.
Now I have full access to hundreds of pages and all the missing instructions that the pages already kindly supplied by varooom showed the various links to, but still the instructions are not clear enough to proceed without running the risk of breaking some trim parts in the process which I'm not happy in doing, the car apart needing a good valet is in mint condition and I want to keep it that way.
So I contacted my dealer and the VWaudi Tech in my city for quotes to supply a new seat belt in colour and fit it, VWaudi Tech, £390 and my dealer £302, so I've booked in with the dealer, who has looked after the car from new and were originally looking at the end of Sept before they could do it. Then they noticed that their records showed it was not only due for an MOT, but also it was time for the brake fluid to be changed, and its service was due in 4 weeks time, so they have now managed to squeeze all 4 jobs in on the 5th Sept, well done them. Its also Tax and insurance time so its going to be an expensive couple of months.
I thank all the members for their very kind efforts, but the parts shown in the manual seem to be different to those fitted, and the screws mentioned don't exist and I have other trip panels that sit above the one I need to remove, but that has to be removed first, and the manual makes zero mention of that at all 😲.
Now I just need to return the 2nd hand belt for a refund.
