Vehicle Information
Rear Washer Nozzle Drips after Use
The water from the rear washer nozzle continues to run out after washer is shutoff. (Illustration 1)
Technical Background
Rear washer hose retains washer solvent after use. Without a check valve the excess water will continue to drain off out of the washer nozzle.
Production Solution
No applicable.
Service
Fit a non-return valve in the hose of the rear window washing system.
Tip:
Observe the flow direction indicator on the non-return valve. The arrow on the valve must point in the flow direction.
Procedure
Assemble the non-return valve as shown (illustration 2):
^ On the first coupling (4) attach one of the connection hoses (1).
^ On that the valve (2) followed by the second connection hose (1).
^ Finally the second coupling (4).
Now the valve is ready for installation.
^ Remove the trim of the rear hatch according to the repair manual.
^ Mark the washer hose directly between the clips (illustration 3).
^ Detach the hose from the clips and cut out the marked section.
^ Put one end of the valve into the hose (illustration 4).
^ Push the shrink-fit hose over the non-return valve (illustration 5).
^ Connect the other side with the washer hose.
^ Align the shrink-fit hose equally so that there is the same amount of excess length on two ends of the valve (illustration 6).
^ Make sure that the system is tight by warming up the shrink-fit hose till it completely enfolds the valve and fit it in the clips (illustration 7).
