To fix a pedal not returning fault pipe with plastic chamber
Phatvalver:
Nice one, thanks for that...
The plastic chamber is the clutch bias valve which apparently controlls the pressure applied to the slave/clutch.
I did question myself if this could be faulty...
doylebros:
I'm Interested in how you progressed with this fault.
Phatvalver:
Hi,
I tbh am about to break the car i think... :fighting:
I have since pressure bled the system to which it never solved it
I have vacuum bled the system to which that never solved it
So i give up and take it to a well rated vw specialist in the area and he drives it 200 yards up the road!
He says its not a hydrolic issue its mechanical.
We have tested for end float in the crankshaft and its fine!
I have spoken to alex at aks today and he says it could be that the intermediate shaft in the gearbox has play as this is common for my age of box :confused:
And the shaft is moving in and out which is causing the pressure drop and gain...
Altho he is extremely knowledgable i have sat here thisafternoon trying to work out how that can give my symtoms as the shaft slides through the slave and applies no pressure to it??
I maywell be totally wrong here so im not going against his word atall.
I will endevour to remove the box and investigate.
doylebros:
Why I ask we got one today pedal stuck to the floor (tried all sorts ) then they changed that pipe c/w valve and fixed it.
