Help with ABC noise please (video attached)
I have recently changed my ABC pump as it wasn't supplying enough pressure and often shut the suspension down.
Just before I installed the new pump I noticed a hissing sound coming from the area of the pump, as the pump was shot I put it down to being that.
With the new pump installed I am getting the noise still. It is best heard when the engine is switched off, if the car is cold the noise lasts a couple of seconds, but if the car has been driven/or suspension worked up and down the hissing can last a good minute after the engine has been shut off.
I have bled the lines in the wheel wells, but am still getting the noise.
Here is a link to a video showing noise;
By the way I have only managed to bleed air out of the system with car in the raised (2 lamps on) position as I cant get jacks under. Will this still bleed the system?
