Grandeur damping adjustment fault

I've got a Grandeur too, and that adaptive damping can be a real pain. Sounds familiar. Are you experiencing a consistently bumpy ride, or does it change depending on the road surface? Have you checked the simple stuff, like the connections to the dampers?

Yeah, it's consistently bumpy, regardless of the road. I took a quick look at the plugs I could easily see, but honestly, I'm not sure what I'm looking for. What kind of connections are typically dodgy on these systems?

Okay, consistent bumpiness points to a specific damper issue or a central control malfunction. I had a similar issue that turned out to be a corroded connector on one of the dampers. However, diagnosis requires specific tools. I recommend getting it checked at a workshop. Could save you a headache in the long run.

Thanks. Took your advice and brought it in. You nailed it - corroded connector on the left rear damper. They cleaned it up and re-seated everything. 95€ later, and the ride's smooth as butter again. Appreciate the help!
