I started up the 08 L322 and moved it into the driveway for its weekly startup and all was well, wife came out to sit in it again as we are in a L405 now and she opened the sun roof and said how she missed driving the car. Then the sunroof got closed and about 20 seconds later a suspension error popped up on the dash saying normal height only then a crazy hissing/bubbling sound started, thought it was under the car so looked around and nothing, got back in an realized it’s the sunroof drain blowing air and water up. Not sure why, how or what the issue is. Never seen anything like this. Are sunroof drains and suspension lines close to each other to cause this? Suspension is still working fine and going up and down and holding its height right now.

The air tank is making a pinging sound now too

Had this with my l322, the sun roof drain on right side wasn't pushed into the sill properly and was touching the air tank so eventually rotted a hole in the tank, I would look there first.

Is that down along frame by air tank? I pull right side wheel liner not to long ago to look at the valves in there and looked good, looked up at tank but have the oem running boards so that might need to be removed to get in there a bit better. Might be a week or two as it’s 104degrees out today and close to that rest of week. If there is a hole in the tank, I’m sure it can be welded up.

Thank you for the info
