Hi all,
My D3 suspension is refusing to raise. The compressor is silent but if I run an independent 12v supply direct to it, it runs but car still won't rise. Have tested the relay and all associated fuses.
Fault codes are:- B1B02-28 low frequency coil - general signal failure. B1C57-14 passive start ignition relay coil circuit - general electrical failure. C1A36-01 exhaust valve - general electrical failure.
Am I right in saying that the Exhaust valve is part of the compressor assembly ?
Anyone got any ideas on what to test or look for ?
TIA.

from memory, the exhaust valve is commanded from the pilot exhaust valve which get pressure from the silica bottle and is commanded via a solenoid. Usually if silica are aged they become like sand clogging air valves pilot exhaust included.
I will start checking silica bottle  - Easy-Lift suspension module 4.0
- GoodWinch 9500 lb
- Full underbody protections
- Tree/Rock sidebars
- Prospeed roofrack & ladder
- Compressor guard
- Raised Air Intake
- Driving lights (2+4)
- 50 mm Waffle boards
- Altox Heater control

- Rear seats entertainment
- Front & Rear camera
- GVIF
