GX air suspension problem

Sounds familiar. I have a GX as well. Had a similar problem where the ride height was all messed up. Do you hear the suspension pump running longer than usual or at all? And are all the air struts looking okay?

The pump seems to be running, but it's hard to tell if it's for an excessive amount of time. As far as I can tell, all the air struts look normal. What exactly was your issue?

Yeah, that sounds like exactly what I had. In my case, it was a faulty connection – likely a cable or plug to the compressor. I got away with paying 95€ to get it fixed by a mechanic. I would recommend taking it to a workshop, they should be able to tell you more.

Thanks for the info! Based on what you've described, I'll get the cable and plug connections to the compressor checked out at a workshop. It was indeed the cable or plug connection that was defective. After it was fixed, I no longer had the error in the speedometer.
