Ok, service and Lanoguard done... but I don't have any pictures... I was really under pressure; it was a favour and I don't think the lads were none too keen me being there - it was a very busy body shop. The access was stressful, very narrow with a sharp left entrance. But it only took 3 hours - I had to wait while they finished a couple of jobs and then moved cars. I had to reverse out, very gingerly.
Everything went easily though. My car does have the plastic under cover bracket. It had just not been properly secured - they are in good condition. Liqui Moly flush for 10-15 mins at idle; cap off, lift up, sump plug loosened, lift lowered a bit, then drain; new Bosch oil filter, new sump plug and Liqui Moly 5w30 goodness added. Oil service reset and then on to the Lanoguard. Underneath condition is excellent, only a little suface rust on the fuel tank strap and the mounting point seams, where the underseal has come away. A liberal coating first of the Lanoguard grease on all bolt, suspension or otherwise and the starp/seams. The the spray, which was very easy and convenient to apply with the included, spay attachment. All vulnerable areas, generously sprayed and the particularly the subframes; around the rear lower wishbone arms, and in any holes through the palstic underguards. Double check and then down, and waiting to get out.
