Hi, can anyone advise please. 2006 RR HSE (Aspirated) 4.4. At the moment, we are bottomed out on its haunches.
Using the Nexdiag have the following codes coming up:
C1A72 F L height sensor, C1A27 Compressor circuit, C1131 Air supply, C1A03 F L height sensor, C1A03 F R height sensor, U0416 Invalid data received from vehicle DCM, C1A07 Cross articulation, C1A20 Pressure increases too slow when filling reservoir, C1130 Air spring air supply
Ran data stream in real time:
Have 4.9v registering at each sensor. and 0.65A to control module. Have 0A showing on valves and reservoir at the moment.
Main issue seems to be the 102Kpa in the gallery which should be the reason I’m on bump stops.
Question is, if the height sensors have failed, would this stop the compressor from generating sufficient air? Or is it more likely this is a compressor fault and the height sensors are showing in fault because they have bottomed out which is my feeling.
Meant to say this was not a intermittent fault that deteriorated, it was suddenly down on its haunches.
help/advice please, Im booked into a RR/LR garage as I dont have the facilities to do it myself, trying to get a handle on possible scenarios and cost.
Thanks in advance
