2008 L322 SC code C1130 and C1A00

I searched, didn't find anything like this issue. I recently had the front air springs replaced and while it was apart, we opted to replace the front ride height sensors. It seemed ok for a few days but then I got the "Suspension Fault" error. I pulled codes and get the generic C1130 and C1A00.

What I've noticed is when I'm driving and come to a stoplight, the front driver side lowers. It is as if the system is putting too much air pressure in that spring and when I stop the truck it releases the excess air to get back to normal height. When I look at the 4x4i view it is showing the truck at normal height at all times.

Any ideas? Nothing is sagging & nothing seems to be leaking.

It sounds like your front valve block may have an issue, you can spray soapy water on the airline fittings and the block valve to check for leaks. Does you Range Rover hold air all night?

Yes, it holds air all night, no sagging or leaking. It just seems to over-inflate the front driver spring.

If you replaced the sensor, was it recalibrated?

Interesting thought! One of the new air springs failed after a few weeks and this behavior started after the replacement air spring was installed. I'll check that, thanks!
