Thanks everyone for your responses. I'll let it go. I will make some visual checks and have a sniff then get on with enjoying the van.
I'm convinced that's all you need. No need to read below unless you want my reasoning.
I recieved a letter from VW for a gas system safety recall because there was uncertainty of how tight the connections might be. I did create a thread about it but it would seem I'm the only owner to receive the letter on the forum.
Anyway, its been a right saga over nothing. The dealers are not authorised to work on the gas system and after months of delay they found a caravan and motorhome dealer (and by the look of your nic-name I's suggest its the same dealer and the same caravan place) and set up the visit....sort of.
Heres where it gets really poor but I can tell you what you'd get for your £60.
I took it to the place and the guy looked at me blank asking me what needed doing
I told hm about the letter and asked if the dealer had given them the instructions from VW...answer? NO
What are you going to do then? I asked. Do a pressure test and check all visible joints was the only option.
Are there any joints that aren't visible? I didn't know and nether did he. I suspect not but a poor situation.
I showed him all the visible connections that are...
Either side of the isolation switch under the hob and these had a painted white line across them which indicated to me they had been tightened. Asides which if you turn that to the on position and turn the gas bottle on in the back you would sure as hell be able to smell a leak.
The only other visible ones are in the back where the bottle sits. He disconnected the orange hose from the elbow and fitted the pressure testing pump. This held pressure for about 5 minutes so on his experience he deemed that to be a sufficient test.
He checked the regulator connection, refitted the orange hose to the van side, lined up the flow to the burners and we sniffed and performed a bubble test.
Thats it...
A very poor experience for a safety recall.
You could do all that except the pressure test (which is not absolutely necessary) so no need to disturb the orange hose.
I'm now waiting for VW to confim there are no non visible joints that should be checked (even though my gas bottle has lasted 15 months so far and left lined up for days some times with no smells).
