Chasing similar issues myself for months, my diagnostic told me the issue was the front left height sensor but having replaced it noted both the rear sensors were shot so could be something completely different... helpful in know but don't just blindly follow the diagnostic.

Could be a failed ABS sensor. My 2004 4.4 had that, with that warning. If it is that, check whether the cause is a driveshaft swollen by corrosion fouling the sensor, if so that needs sorted too. Only Range Rovers since 1988 |

How did you fix it? What was the replacement part number in your case? |

I live in a desert - last snow was in April and next one will be in October. If we exclude moisuture induced corrosion, what else? |

Sorry I can't help with a part number as I got the dealer to do it, and I no longer have the receipts for that car. It's probably best to get a diagnostic check done first. I take your point about corrosion being less likely where you live. Only Range Rovers since 1988 |

I had the same thing but eventually went away when I started driving the car more. I had let the battery voltage get real low while I was doing a bunch of work on the car. I charged it back up on a slow charger to where it would start again but it still wasn't 100% charged.

Are we talking about this?
I unscrewed it and looked at the part number
They are running about $150-$300 on eBay but there is disclaimer that you need to recoding. Do in addition to $150-$300 do I need to buy a separate tool for >$400 just for recoding? |

You see that big plastic thing, look behind it, the lump of steel with the brake pipes in it, that will have a set of numbers stamped/etched into it, match them up no need to be coded

So do I need to remove the ABS unit first like I did to read the part number? |

So you did not even replace the ABS control unit, just cleaned it? I tried to unplug the cable, it did not work - are there any clips from either side that need to be taken care of to be able to unplug the cable? Also, did you just unplug the cable or remove the ABS unit first and then uplug the cable? |
