Ok I've been getting the abs hdc dsc faults on and off for the past year. Every time I would drive 15 or more continuous miles I'd get the faults, suspension drops to access only. If I shut off the lr3 and restart it, the faults go away. I've checked/changed everything. Brake bulbs, brake switch, new battery, checked and changed abs sensors, checked wires for corrosion on passenger and driver side. Also the wires on driver side by hood release. So today I decided to check my compressor and I sprayed some soap water onto the hoses and collets and where the two lines go into the front of dryer the soap water was fizzing, bubbling. Would this cause a suspension fault? Or do these compressor leak like this? My truck's suspension doesn't drop down overnight so thats why I never checked my compressor. What's the fix? Do you think it drops every 15 miles or so because the compressor is trying to compensate/keep up with the leak? I've included a video below. Thanks.

 

maybe the leaks are causing extended run time on the compressor tripping the faults?

 

"maybe the leaks are causing extended run time on the compressor tripping the faults? x2. "


your compressor should not be leaking like that, it will run continuous get hot and shut down, before it burns up altogether.

 

Try unplugging hoses cleaning and plug back in see if leaks stop?

 

I decided to buy the new drier cover plus new beads, orings and filters to refresh my drier/compressor. Hope it works.

 

But if I shut the truck off and restart the faults disappear and suspension is normal again. It's usually every 15 plus miles it faults.

 

Chances are your drier assembly cap is cracked or the push fittings are no longer strong enough to make a tight seal. The drier assemblies are now available again through Land Rover, I have 2 in stock if you need one and do not feel like rebuilding your old one. $140/delivered
