EHC code 35 and 36

[nextelbuddy]

Hey guys hope I can get some help on this.

Air suspension error codes

EHC 34 Reservoir-pressure-sensor

EHC 35 Supply Reservoir-pressure-sensor




Reinstalled my complete air suspension system.

Pump, lines, accumulator


- 4 new arnott air bags
- 4 new level sensors
- Have tried 2 known good pumps
- brand new accumulator pressure sensor on the accumulator itself
- tried 2 different EHC2 modules
- voltage from all 4 sensor looks good



These 2 errors are instant, as soon as you clear then they come right back.

Air accumulator pressure always reads 9.7 bar and doesn't go up or down in INPA


I can manually raise the X5 with INPA and it holds pressure over night no problem.


Not sure what else I can replace besides the actual valve unit itself
