  1. P38 Spring Conversion, no Cruise Control or Speed Limiter

    Range Rover Mark II / P38
    Hi all - new to the P38. So far just shoved a new power steering box on, steering dampener, brakes etc. However one thing that bugs me is that no matter what speed I go the speed limiter just flashes 20mph until I turn it off and the cruise control doesn't work. Is this to do with the spring...

    Hi Guy's, as the title says, my 2011 RR needs the ACC calibrating. im assuming that this isn't something that can be done by myself ?? so does anyone have any ideas on the cost of this? Many thanks in advance ASH
  3. Cruise Control dying

    Range Rover Mark II / P38
    For the last 15yrs I have owned and driven daily a '99 4.6 HSE. I have replaced and repaired many parts over years but it is generally in pretty good shape. 225k on clock and still going strong. Lately my cruise control dies after about 10 - 20 mins on road. Once it dies it won't start again...
  4. Cruise Control Still Faulting After Spiral Cassette Replaced

    Range Rover Sport / L320
    Replacing the spiral cassette coupler in the steering column fixed a litany of issues in my steering wheel controls, but from time to time I'm still getting the Cruise Control Not Permitted Issue popping up albeit far less often and more self-correcting than before when it was always there...
  5. 2000 P38 4.0 cruise control not working

    Range Rover Mark II / P38
    I was driving on the highway and tried using the cruise control for the first time in the year that I have owned the car and it wouldn’t work. Whenever I press the set/reset button I can hear a clicking or humming sounds. Yes I know you must enable the cruise control with the button on the dash...
  6. Cruise Control doesn't turn on -- 2006 RR HSE

    Range Rover Mark III / L322
    Happy new year everyone. I have a 2006 RR HSE and cruise control together with the heater blower stopped working simultaneously. This happened a few days (not immediately) after I was fooling around with the fuses (in the back and in the glove compartment) hoping to fix the wiper delay that...

  9. Cruise Control - 1999 NAS 4.6 HSE

    Range Rover Mark II / P38
    Hello all, I was curious if my cruise control is just annoying or if there is something to be done to make it less so. Simply put, when I engage the cruise control, the vehicle surges slightly to keep up the speed, ie: set at 105 km/h then the truck fluctuates between 100 and 105. Speeding...
  10. Radar cruise acceleration settings

    Range Rover Mark IV / L405
    I have a 2018MY full size with radar cruise. The owners manual tells me that I can change the speed at which the car "resumes" via the in-dash menu.... but I cannot find the menu. I can see how I change the "follow gap" via steering wheel buttons, but not the glacial pace at which the car picks...

    Range Rover Mark II / P38
    Ok, so got me a latter style replacement cruise ECU with plu and 2 inches of loom. However when i've tried to wire it in the colours aren't matching - i did the same to my previous 97 4.0 with no issues. however checking rave non of the schematics match - i have Existing harness Orange/red...

    Range Rover Mark IV / L405
    Hello all, i used to have 2018 RR TDI and have issue with adaptive cruise control, when I turn it on, vehicle stop with driver intervention warning message with sound, my dealer was not able to fix this and informed me land rover aware of this issue but does not have solution for this, and I...
  13. RR Sport Cruise Control

    Range Rover Sport II / L494
    Hi, I have a MY17 RR Sport and when I use the cruise control on a long trip it does not hold the speed when going downhill. I had it set at 110km and going downhill I looked at the speed and was doing 135km/hr. I have been told that this is normal with the RR and they don’t hold speed. Is this...
  14. Cruise control inhibited

    Range Rover Sport / L320
    The only code that seems to be popping that is related to this is the P0679. The info triangle pop up on the dash with a ding and i cannot enable the cruise control. Turning the car off and on seems to clear the issue. Any thoughts?
  15. Cruise control buttons

    Range Rover Mark II / P38
    Hi all, Quick question...the cruise control buttons on my steering wheel, left one feels distinctly dodgy, right one is fine. As it should be, diesel so the reset (right) isn't used. Is it possible to prise off these switches and swap them side for side? Don't want to attack it until I know...
  16. Adaptive cruise control blocked

    Range Rover Mark III / L322
    Hi Guy's, after recently buying my newer range rover (upgraded from a P38) I've got a sensor blocked message for the cruise control. Now, I'm thinking that a precious owner has put an autobiography front end on & I'm thinking that the sensor is blocked by the bumper as it may be in a different...
  17. '18 Adaptive Cruise Control changes?

    Range Rover Mark IV / L405
    I have read on the literature that the '18 has "upgrades" to the Adaptive Cruise Control. I have to say, my '17 HSE TD6 is absolutely scary compared to my BMWs. In general terms, cars can be at a complete stop 1/4 mile or so ahead of you and RR will accelerate until it gets to the spot where...
  18. No cruise, button doesn't light up when pressed.

    Range Rover Mark II / P38
    Hey guys, My P38s cruise doesn't work and when I press the button it doesn't light up. Any thoughts on why that might be? Everything else works just find, the only light I have on is an SRS light and I don't see why that would matter.
  19. Diesel cruise control stopped working

    Range Rover Mark II / P38
    After bragging to a friend that the P38 is now 20 years old and after 11 years of ownership it never gives any problems (big mistake:naughty:) the old girl hit me with a handful of headaches all at once. First the cruise control just stopped working. The switch lights up but nothing happens when...

    Range Rover Sport / L320
    Hi there everyone. Im a new forum member so hello! I have a question about adaptive cruise control module compatability. Mine was involved in an accident and I think it needs replacing as I keep getting the radar blocked message looking for a replacement on eBay I’m wondering whether I need a...
