As regards my knocking noise in & under car I have been advised to change the "Pulsation Damper" (52a attached pic)
Has anyone ever done this or had same problem?
It's like a knocking noise under the car, as loud in the back as in the front.
ABC pipe burst recently but I stopped car immediatly and did not run pump dry.
It has also had a new A/C compressor.
