The air suspension is far more reliable than it seems because the vast majority of people it's working and they aren't posting.

There is a kit to rebuild the compressor when it fails.

If you have a good scanner you can program the heights to fix if it's not level.

My air suspension made it to 205,000 miles on original air springs. Had to replace both the level sensing arms.

Wife's e 70 had to replace the air springs at about 70,000 miles.
