Err, I had a natter with a rather Northern accented gentleman at Westroen and the warranty only extended (in my case) to blown ones. Not ones that had dropped in pressure. I naturally queried this.
He (as I recall) got a bit defensive and asked how I had determined the spheres in question were low and from where had I got my information. When I said I used a pressure tester on them and consulted the charts in the factory manuals, he got even more defensive and hinted that I might not quite have a full grasp and understanding of Citroen hydraulics.
The conversation was terminated thereafter.
In his defense, the remaining ones, when tested in July, were still just about borderline serviceable after four years in use...
Regassed ones can be a lottery in my experience. I've known of two loose every bar of pressure just sitting in stock...
On to happier things - Robyn's 18th birthday celebrations went extremely well, culminating in a big party last evening/night. A great time was had by all and everybody was extremely well behaved
It was a very late night and I've been recovering a bit most of today
I was proud to take Robyn to the party in my Activa - not quite a Limo but the next best thing

She was hoping for the cream leather V6 but was happy with the Activa...
One thing I noticed again last evening with the Activa and have many times in the past, is how the rear window is so enthusiastic about steaming up at the slightest provocation. My others don't do this and nor do they rain water into the boot when the tailgate is soaking wet. I had a little investigation today and might have found the cause.
Firstly, I had the boot carpet up, mindful of leaks in the past and my concomitant paranoia about them, as dry everywhere as a Temperance pub so that was not the issue. The I looked at the "raining" issue and found the water was pouring from a gutter under the lower edge of the glass. Just under the glass edge is a channel designed to catch and water that might leak past it's seal. This channel is open to the inner surface of the glass and has drains on each side of the tailgate - water was pouring profusely from these after a good downpour whereas on old V6, hardly anything at all.
The culprit turned out to be a very loose gland on the rear wiper, the black one just below the arm. This was allowing water to run into the channel and fill it. Over time the water evaporates and condenses on the inside of the screen. The gland just needed tightening up...
Time will tell if this was the reason or just another red herring...
Still, at least I know the car is unconditionally dry now... That's good...
One little thing I rescued when we were clearing up after the party was an empty helium balloon gas cylinder. They're disposable but it seemed like it might be useful for something...
Not sure what just yet. Any ideas?
