HDC Fault and Fix Land Rover Discovery 3 & 4

HDC Fault and Fix Land Rover Discovery 3 & 4

This fault occurred on on my LR 3 recently.

The display read:
HDC Fault System not available
System Fault Special Programs not Available
And the air suspension dropped to the low position

Firstly I checked the battery which was a bit low. Charging was good at well over 14 volts. The battery was over 6 years old so I replaced it with a new Varta without any effect.

I traced the fault to a loose plastic ring on the steering column, that should turn with the column and operate the steering angle sensor. I have explained in the video the steps I took to repair it using some Areldite epoxy resin.

The Areldite type I used is available on Amazon (I used my own syringe):

This is the twin syringe type:

A know issue with an HDC fault is a faulty brake light switch: https://amzn.to/3oQLLi0
