Tried leaving the door open for 30 mins. Compressor got hot but nothing else happened.
Presumably Monsieur Renault would be able to attach his airline c/w pressure gauge to the tank feed. Would a leak from one of the individual airbag feeds give the result of no pressure to any of them or would the valve block isolate it and inflate the other three ? I am anticipating discussing the options with M. Renault who of course speaks no English, and definitely no Rangeroverspeak, so it's very much a matter of the blind leading the blind, with much of the EAS jargon being outside normal French vocabulary , his and mine !
Can you not get it to Monsieur @Mark Piercy and cross his palm with low grade cyder? The stuff you strip industrial acrylic paint off bridges is his usual tipple (before breakfast) unless I am mixing him up with another member.
