I’ve just completed a service on lgv med and I had vacma on , the hud displayed the circle where a yellow light appears when vacma rings , but in the 84km journey vacma did not ring once . Vacma does tend to ring a different number of times each journey , but sometimes it doesn’t ring at all . Anyone else found that vacma isn’t responding and working like it should ?
I think it depends on how active you are using the controls in the cab. If you are frequently say blowing the horn, Vacma will not go off because it already knows you are still alive. If you are just sitting there not doing much it will go off quite a lot because you have not used the controls in a while and needs to check if you are still alive. Hope this helps
