    Hey guys. I'm having issues with my LR4 2009 suspension. After bushings replacement, a message pops on "suspension faults" and "maximum 30pmh" and it lowered down completely. Then I pulled over and off the engine. After a couple of minutes I started it back and the suspension sets back to normal hight. It keeps coming back at 80 km/h.

    Please I need a help to fix this problem. Thank you

    Schmerge probably nailed it.

    If it were a height sensor problem, it would very likely do that every time you started it.

    Swing by your favorite parts store and ask them to scan for the code it is throwing to confirm it.

    Schmerge did nail it, you have to do a calibration routine on the steering anytime there is a major change to the front geometry. The way it was explained to me is you have to tell the truck which way it's going. I had this issue after some front end work and spent a month and getting to the point that I put the truck on FB marketplace I was so frustrated. Someone said to run that calibration which I did with my Nanocom and it's been right ever since. That was 9 months ago.

    Hey guys, I’m having that same problem with my 2012 Range Rover Sport with 51,000 miles. When starting after seating for 2-3 days my truck raise and after driving for 15 minutes my fault suspension come on and unable to drive over 30 miles per hour. Own the truck for almost 3 years with no problems.

    I'm assuming it's throwing a code?

    This happened in my 2013 LR4 after a flat front tire. I have the lift rods on and had to put the factory rods back on to run the calibration. After that the lift rods are back on and no issues since.

    My 06 RR Sport did that and still trying to figure that out. When it sits for a few days it will drop off and come back up when I start it. It Has Suncore Air on the rear so assume that's not stock. Any Ideas?It dropped down in the rear and had to limp it home at 30 MPH.

    What am I missing here, I replaced my LCA's in the garage and had zero issue with height sensors no codes ect. When my battery went bad I just replaced it with just like battery and had zero issues. What am I missing? Is there some special voodoo doll I am supposed to program or what?

    Ok gents, attached is 26 pages of mind numbing information on your suspensions. This is from the LR3 manual but 90% applies to your LR4s and RR Sports. Read it through and it will help you undersand the complexity of the system. The first page alone is enough to make you trade for a Toyota let alone understanding the interaction between the sensors and the computers and components.
    Yes, it is voodoo...
