Hi all
After having a suspension light pop up on the dash i read the codes and it came up as C1A20, so felt some investigation was needed.
On looking at the pump I have discovered the air is leaking out of the pump where the push in pipes go, the red and blue ones.
So my question is are any of the repair kits anygood?
Has anyone used one successfully?
I am looking at the one pictured

Yeah the repair kits are good

Better order one then

Just fitted that kit on my Hitachi as preventative measure.
New silica and filters, and alu end cap.
Easy enough to take the air dryer off leaving compressor on the car.

That kit does not have the piston "ring" and glide - you will need that as well. Also consider the replacing the exhaust valve and housing.

I dont know why these kits do not include everything with the option of buying just the bits you need.

I rebuilt mine a couple of months back and it still leaked internally which was the exhaust valve sticking open - fixed that and the pump is now all good - no codes.
