[yas_b]

1. hi i got this fault code (16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow ) ages back, evap sensor or canistor whateva its called i rang the dealer for the price and they didnt know what it was.
2. is it the charcoal filter? the black circular unit with two pipes coming out of it below the drivers headlight? if it is i just replaced that yday this time and erased the code light went off everything fine i assumed it was this as when i removed my old one it was making a rattling noise inside as if somethings broken anyways lights just come back on now today after 24 hours

on ross tech it says
Possible Solutions

• Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
  
  • Perform Output Test
• Check Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115)
• Check Evaporative Emission (EVAP) Canister
  
  • Perform Basic Setting
• Check Pipes between Tank Breathing and Throttle Body

can anyone point out to me where the solenoid valve is located or show me a picture of one plz

and i assume pipes between tank mean the two pipes on the canister they go to the throttle body??
