I exhausted this last winter but I'll try again.

When the air temp gets below freezing my rear airspring leaks. It got down to 25 degrees last night and I came out to a car on its bumpers this morning.

I've done all the soap tests to the lines, fittings, and bags. Took it to the dealership and they could not find a leak. Replaced valve block and it still does it.

Here is my question and a theory I have. I think I will remove it and separate the spring from the shock. It appears that there are two rubber gaskets in there that could potentially be causing this problem. My question to someone that has pulled one of the rears off -- Is this a potential leak area? Or is the bag self contained?

the O rings can become more brittle as the temps drop.

separately. Otherwise, soaking them in WD40.

If you can't get them separately, buy the upper strut mount, the repair kit comes with the rubber o-rings. I've just ordered a kit from genuineaudiparts.com for ~$30

I think I just ordered the same thing from them: 4z7698506. Dealer did not have the kit in stock.
