As you'll see from the IID footage at the end of the video, the front sensors were pretty unhappy. So for the sake of £70 I change the front and rears which has now completely sorted the dogey responses and warning.
Hi. I use the GAP IID tool to monitor the height sensor voltage for each of the sensors in the RLM Suspension section in Live values. You can also monitor the height sensor supply voltage too to ensure the sensors are getting the right power and that there isn’t damage to the loom feeding the sensor. Good luck!
