Air Suspension fault - C1A18-64
Hi All,
For the past few weeks, i have had an intermittent suspension fault C1A18-64. It hasn't progressed in dropping to the bump stops, or going into limp mode and is easily reset able by switching off, locking and unlocking.
Has anyone experienced this and if so, what was the rectification?
cheers

HI All,
so i have replaced the rear valve block and serviced the compressor (replaced the desiccant and filters) and the problem still persists, albeit very intermittently now.
Any other ideas?
cheers

Have you done the soapy water test on the dryer end cap?

Reservoir valve blocked/ stuck/kaput!
from the workshop manual:
C1A18-64
The pressure increases too much quickly when the tank is filled
- Plausibility error signal
Tank valve jammed in position closed (mechanically)
Conduit pipe obstructed / damaged / crushed
Tank tube clogged air /damaged / crushed
Using the diagnostic system approved by the manufacturer,
test the operation of the tank valve (interface of the vehicle's ride height)
Check for presence of obstructions / damages / crushing of the hose conducted
