my understanding of purge valves in general is that 1/  it's fed "permanent" live (key on) from the main relay(easy to check)  and 2/ is then pulsed (to earth) thro' /by the ECU,  with some VAG stuff this will NOT happen with the tank >85% or<15 full  hope this helps

thanks 

which one is main relay? is 458?

so far ......

1)EVAP purge valve resistance 26 ohms

2) I replaced relay 458,460,167

3) replaced all fuses 

4) replaced Purge valve 

5) checked continuity of cables from valve to ECU

 

no result ...........

If you run the car with the N80 unplugged, do you get a different error?

one new code ---after i disconnected EVAP purge valve and started engine .

 

01092 - Switch for Stowed Canopy (F171)

+ same '' 17833 - evap purge valve (n80) short to ground''
