Hi guys We have a 2017 volvo ecr88d that has a habit of pulsing through the servo mainly when gently lifting the boom, if you lift the boom at a faster speed it isnt there, it tends to be there when feathering the control. Cant say i really notice it on any other action. Anyone come across this before? Also notice through both levers when doing any action you can hear the oil pressure but you can hear the pressure still in them after a second or so even when you let go of the levers. Machine has a pattern change also and does this pulsing when in both style of patterns. Any volvo gurus here Regards Matt
