Land Rover Repair/HDC Fault


Hi John,  I have a range rover sport 2008 2.7TD. I drive it for around 4-5 miles and the HDC fault indicator comes on and lower suspension etc. I pull over take keys out of ignition and restart and it clears again. Then drive for 4-5 miles and the fault repeats. I have had a new alternator and battery fitted approximately 6 months ago and I tried changing the brake lights etc. but the problem still there.  Have you any suggestions on what it could be?

The only way to diagnose this is with the Land Rover dedicated test system. They can talk to the HDC computer and a see what's going on.  The generic consumer scan tools can't do that.  Main dealers and some independent specialists have the tester for this job.
