PROCEDURE:

This repair step applies to all models.





1. Locate the purge valve (Y58/1) (Model 129 shown) and utilize two hose clamps, Part Number 003 997 9190 at the connection (arrows, Figure 2), to ensure maximum clamping efficiency.

Use only clamp type hose clamps as described, do not use screw type hose clamps. Additionally, to avoid damage to the hoses/pipes, ensure that the hose clamps are correctly installed i.e. not crocked and/or over tightened.

This repair step applies to Model 129 only.





2. Locate the flexible hose in the fender well area (Figure 3), then check and replace if necessary, the two hose clamps (arrows, Figure 3), part number 005 997 8390, to ensure maximum clamping efficiency.

(!) Use only clamp type hose clamps as described, do not use screw type hose clamps. Additionally, to avoid damage to the hoses/pipes, ensure that the hose clamps are correctly installed i.e. not crocked and/or over tightened.





As an overview, please see Figure 4:
The two vertical arrows next to Y5B/1 show the location of two clamps for all models as indicated in step 1 of the repair procedure.

The two horizontal arrows which show (as shown on the vertical line) the location of two clamps, are for Model 129 only

After all clamps are installed, please check the fuel evaporation system for leaks, as described in the Diagnostic Manual section. Have the OBD system perform a "self check" of the leak tests before the vehicle is released to the client.





Operation: If needed. install hose clamps at the purge valve connection (all Models) and hose clamps at the flexible hose (Model 129 only) in the fender well.
