Thread: Ride height fault

last week we had a fault come up C1A69-1C1C(28) cleared it with my Gap scan tool, then 2 days later came up again but different C1A07-62 (AF), (photo) also did live value voltage on height sensors (photo) r/f was much lower than other 3, I ordered 2 new front ride height sensors for front, we fitted both this morning, calibrated ride height and adjusted then checked voltage and was still the same, so probably there is no problem with the sensor at all, we adjusted r/f ride height up 30mm and voltage changed from 1.8 to 2.0v.
When fault comes up car lowers slowly onto bump stops I turn car off restart and then it requests ride height, I raise it to normal height and car is fine, can drive an entire day with no problems another day it will happen 3 times, hasn’t happened whilst towing caravan, am at a loss as to what it could be.

Perhaps not related but check the wiring harness that runs behind the right rear seat. It has a habit of taking a short-cut under the rear seat mount resulting in damaged insulation and wires intermittently contacting each other.
