Just back home after a visit at my lokal Vw-dealer.
Have made a really good friend there and he allowed me to take a look in their repair-manual-program called "ELSA"
AND GUESS!!!!! I found a page called " Change the residual pressure retaining valve"
You can replace it if the sealing leaks, or thevalve have been messed up.
Now the new problem..... The "residual pressure retaining valve" is not a sparepart in Sweden.......strange.....but you have a manual in swedish how to change it!!!!!
Does anyone know how a " residual pressure retaining valve"
look like when itīs not fitted...
(Yes, the grammar isnīt the best......Iīm from Sweden U know
