Suspension Fault Discovery 4 SDV6 GS

I have a 2013 Discovery 4 and recently attempted to calibrate the air suspension. While measuring the distance from the wheel hub to the wheel arch at normal height, I recorded some unusual measurements:

- Front Left: 515 mm
- Front Right: 525 mm
- Rear Left: 553 mm
- Rear Right: 565 mm

To troubleshoot, I decided to deflate the system using SDD with a JLR Moongoose cable. However, the car wouldn’t inflate and displayed the following fault codes:

C1A05-78: Rear Left Height Sensor (Permanent)
C1A06-78: Rear Right Height Sensor (Permanent)
U3000-05: Control Module

Help resolve this.

At a guese I would say you have faulty height sensors
