Fortunate for me I was parked on a car park approached from a lower level and just happened to notice something hanging under the engine (no, I dont know how long its been like that!)
Besides the fact you just cant source any original parts on a bank holiday, I find that these are selling for anywhere from 10-13.00 quid each. Gordon Waters! (as my dad would say, or bl**dy hell for the rest of us)
Amazonk to the rescue - diagnosing found that they are M6 male/male rubber mounts 18m diameter, 10mm depth rubber, with 10mm threads either end. You can get hold of a set of 4 for just 6.99 delivered (if you have prime) from here;

They are not an exact match being 18mm threads and 20mm dia, but you only need 3 and all you have to do is cut the threads down - they fit fine.
Now the purist in me will probably order some VAG replacements at some point but for now; time for a blast
