So Good day, morning, night everyone!
I guess this will be my first post here. So yes i m the newguy!

I m driving Audi A4 year 2000 motor type ATW (Audi bastard child).
I m getting engine error code 16825 "tank venting system incorect flow" so far i know why this error code appears.
My vechile modified to drive on LPG, so in trunk, where is extra wheel and EVAP system right now is gas balon. So there is no more evap system.
My question is how do i can trick this system to not receive this error anymore.
My version is to put rheostat before valve,(in vires between or after plug) so when the system tries to connect with valve, it receives info that there is something on end of the line!
This is one off my solutions, whitch i would like to try. Mybe somebody can explain the system off evap viring?
Or mybe anybody have better suggestions? i m opened for any idea that would help!
I m not driving this car in USA, so my country regulations doesnt ask for EVAP:)
Also sorry for my english, it is only my second language :)
