While I love the ride that air suspension gives us, it can be problematic at times.
I've owned a 2006 L322 for the past year or so and I've had "SUSPENSION FAULT" show up periodically for that time (It basically did this from the start depending on level of fuel and how many passengers).
To date I've changed the ride sensor in the passenger rear wheel well (because the display points to that as the fault) and the total compressor assembly. Now I'm thinking the airbag on that right rear wheel may have a leak or something?

Any chance you guys may have experienced a similar situation, and what are your thoughts?

Thanks and I'll appreciate any help you can give me.

Julian.
