Awesome man, looking forward to hearing updates. Glad it has stayed level but sometimes the side that is leaking will sag a big until the bag folds over enough to cover the leak. Maybe that's why it stayed the same.

Regardless, at 10 years old new bags can't hurt!

Bad bag out, new one in. It was damaged where it folds, guess that is why it stopped leaking.

It was easy thanks to the posts here, thanks!

When I squeezed the clip for the hose from the reservoir to the bag together like I did on the other side it broke.

I seem to remember reading I have to buy the entire hose to get it?

The hose won't come off, can I leave this (good) side alone until I can get the hose?

I searched & see I need the whole damn reservoir. I put a large wire tie around the 1/2 that is still there and could not pull it off so I'll order the reservoir.

I put it all back together, dropped it off the jackstands and replaced the fuses.

The compressor kicked right in and the car rose, the new bag made a scary popping sound after about 10 seconds but it kept rising and now it sits at normal height.

Shame that damn clip ruined a perfect job.

hi e30cabrio right, back then you broke clip in attempt to remove the air spring hose...and no matter what you did it would not come off? safe to say that the actual plastic clip is only to disengage the hose?

I proactively replaced my rear bags (also from Arnott) the other month. I used needle nose pliers to squeeze (gently) the plastic clip which opens up the quick disconnect line to the air fitting on the top of the air spring. No issues for me.

I believe (e30cabrio) that the plastic clip is mostly there to help installation / removal rather than sealing. You may be able to push it back on the new air spring's fitting.

If not, you'll need to down the car for a few days while you buy the air reservoir. Look at the bring side, you're saving on parts and labor. If it happened at a dealer you might scorn them for something that you (unfortunately) experienced.
