We’ve got a 23 plate daf CF 18t.
It’s got a weird problem where it says it’s losing air pressure, gives the following warnings
Clean air tanks
Low air pressure
Check for air leaks
I’ve monitored the air pressure display, and over an hour or so, it will drop from mid green to red, forcing me to stop.
When I stop I turn the engine off, wait a minute and restart, and give it some decent revs for a minute or two, the air then creeps upto 3/4 green and fluctuates there for a good few hours - then the process starts again, pressure slowly drops, goes into red, and I have to stop.
What’s causing this cycle?
