Faulty sensor would be my guess. What are the actual readings of the 4 corners on the GAP IID live values? Also look at what the 4x4 screen is indicating for where it thinks the wheels are in relation to where they actualy are. The Voltage anomoly is also an indication of a fault. 2012 TDV8 Vogue (L322) |

Thanks for the quick response. I’m away from home at the moment , so will check the live values when back,hoping it is just a sensor issue. |

I’d just look at the 4x4 screen as a first pass, as it will show you where the car thinks it is. Then have that in mind when you are then looking at the GAP readings to see if they concur.

As suggested by others above, a faulty height sensor is the most likely culprit.

Thanks Jon. I’ve checked , and all rods are connected, and wiring to each sensor plug looks in good condition. I think my next move will be to remove each sensor rod and move them throughout their range whilst checking the corresponding voltage with the iid tool. |

Sounds like a good plan.

Just an update in case anyone has similar problems. The symptoms were , front end on the bump stops and rear end going into extended height. It turned out to be a fault with the LH front height sensor. When I tested it there was a constant reading of around 0.650 v with no variation when the arm was moved throughout its range. As soon as I unplugged the offending sensor, a suspension fault warning came up on the dash, but the fatty levelled itself out and appears normal, even with the sensor disconnected! New sensor now ordered.
