Air spring troubleshooting

[heus33]

Hi guys - first post here (been a long time member on the 'other' forum. New to the allroad, not new to Audis and am having some issues with my left front air spring (passenger side).
The air spring would leak overnight (especially during cold weather). The bag was replaced by a shop with allroad knowledge with a brand new aftermarket bag (not Arnott) but continues to do the same thing. Looking for some common troubleshooting tips here. Anything to help me narrow down the culprit here? The shop is a good 45 min away so I'd prefer to do the repair myself if possible.

Thanks!

Time to get out the soapy water - check the fitting to the bag, and follow the line back to the junction block and fitting at the compressor. Should be the green air line. You could pull the wheel liner and check the line going into the fender as well, maybe it got nicked or something.

If all is good there, then I'd check the bag, even though it's new. Then look into the sensors, or the levelers as a possible issue.

Just an FYI, passengers side is the RIGHT, driver is the LEFT. Perspective is from the drivers seat.

Good place to start.

or the easy first step is jack up that corner (put it in 'jack mode' first) and spray the bag and fitting with anything that makes bubbles
chances are its either at the fitting or one of the two places where the bladder is crimped to the housing

the air line from the bag to the valve block rarely gives problems unless it was wrecked or something else catastrophic happened

Thanks for the tips guys - I'll give this a shot.
