Bailey Autograph 794t 3 series fridge flue recall

further to my post 16/07/23 i  have had the motorhome in for its annual hab service and engine service. i asked for the recall to be done.they said my van needed it.on getting back home i removed my bottom vent on the fridge and found nothing different,therefore i dont know if anything has been done or not.any ideas.Thanks.

again futher to my post,ive investigated further and opened the top vent cover to find that a metal plate has been screwed onto the wooden frame opposite the flue exhaust therefore protecting the wood from catching fire from the hott fumes from the flue whilst running on gas.
