07 cls550 shock down
Going to start searching but woke up to a front passenger shock down. I started the car and it cycled on and off every few seconds raising the car up a little but would not go all the way. I pressed the raise button and it didn't help. Dash just says raising vehicle. No warnings about being low.
I will search for troubleshooting steps.

Ok weird. A gremlin is in there. I do some basic tests. I start car and try different settings. I press the raise vehicle button. I hear compressor and right front trying to rise. It gets an inch or so and I hear an air release. Then dumps back down to stops.
Here is where it gets weird. I stop car and check all around. Driver front and passenger rear normal but driver rear up max. I assume maybe because the front passenger is so low?
Then I lock the car with key and compressor dumps air all around. All four are low now and passenger front is lower than the others. It is on bump stop. I start car again and nothing appears to rise now. I hear compressor try again on front passenger but nothing.
Thoughts?

Found it as a blown airbag. Jacked front up on stands and did a bunch of tests as the car would try to inflate the fronts bags just after starting. Could hear and feel the air blowing from around the strut. Ordered Arnett replacement.

I just replaced the passenger front shock as well, not too bad of a job with the right tools and patience...after searching around, found them cheaper at carID website. Car is back to normal thank God. good luck.

I replaced mine with an Arnett this weekend. Getting the strut to compress was a complete pain. Ended up with the 9volt battery trick. Even then it doesn't stay compressed so used every trick in the book with the jack and jack stand. I popped the upper a arm ball joint but it didn't do too much. Finally got it in there.
I wonder if I should have disconnected the sway bar. I bet the suspension would really have dropped if I did that making life much easier. Anyone else do this on a w219?
