Ride height calibration issue

[msggunny]

So we noticed that the ride height was off on the lr3 and we took it into the dealer to get it calibrated. Apparently the first time they did it, the calibration didn't stick, they did it again and the calibration failed within 2 hours.

The techs said nothing was showing up as a fault, but they were going to reevaluate it again tomorrow. They ate stumped.

Anyone had similar issues?

Would/should bad sensors throw a code?

Thanks

Its pretty common for the calibration to fail. Is your truck leaning far to one side?

I wonder if you have a sensor out of it. There was a new design sensor for the early trucks, they had water ingress problems. Also a couple tsb's about an overlay harness for the corner valve, and pigtail connectors for the sensors themselves. But I would think you would have fault codes for either of those problems. I like to bring the sensors up on the screen in something called data logger. The sensor will show up as a thin line if target and actual are close to the same. But as the target and actual get further from each other the line gets fatter. You would also see if a sensor stops reading by making adjustments to ride height while watching them.

Remind me never to buy an LR3.

Its about 1/2 in low on the passenger side in regular mode, 3/4 in on off road height, and 1/2 in low on access height.

disregard, issue resolved

What was going on?

Suspension faults seem tame compared to the myriad ways older Rovers fail. Maybe I'm wrong. The guys that work on the damn things everyday for years would know better.

the service manager "looked" at it, but didn't check it. Had one of his tech's look at it again and it tested out ok. Its sitting at about 1/4in difference vs 1in now. Will check it again soon.

Broken or bent ride height rod? Or whatever the fuck that thing is called.

This might be sensor failure - related. May not yet show the sensor itself is failed, until it fully fails (i.e. bump-stop fault). I just went through the same thing.
