About 2 and a half years ago I replaced all the airbags in my P38. Some were leaking, some not but they were all original (13 years old at the time) so I just replaced them, for the sake of a clear conscience.

Today, after trying to find out why the RR was starting to lower after 3 or 4 days, I found this:

P38 Range Rover Rear airbag leak - YouTube



I certainly didn't expect to have to replace an airbag anytime soon. If I did I wouldn't have bought new bags all around, I would just go replacing them as needed.

But, I'm thinking that I had a problem with a tyre fitting garage a few months back where they popped the front left airbag and it became separated from the bottom plastic (the bag was replaced with a new one). Maybe the same happened to this bag (rear right) but it got reseatted ? If I take it out, is it feasible that I can remove the rubber bellow, clean it and reassemble it, trying to cure the leak ?

have you spray tested it to see where the leak is?
I replace mine about the same time as you and had a leak in a rear air bag and found a split in it but this may have been caused by sharp stone as i did a lot of bad roads ( I was going to say offroading but that is not correct as the roads were unsealed roads in the stans and turkey) but having said that the split was in the rear of the bag.
I got 2 new bag and one of them was leaking around the bottom seal'

Hmm.. that's why I linked to the video, tried embedding it but it won't work here in LZ.

Well, the leak is small and at the bottom of the bag, where the rubber meets the plastic of the bottom part. And my question is how is this connected ? Are they glued or are they just pressed together ? Can I dissasemble it and reassemble it afterwards, without any special tools ?

If it's a Dunlop OEM type bag, they seat with a bead much like a car tyre. If it's an Arnott, they are crimped and cannot be re-seated.

That was a minute leak on extended height. Not something i would call particularly worth bothering about. 15 mm drop in 24 hours is an acceptable figure.
