Denied Revo tune -P0441 code
Went to get a stage 1 uploaded this morning. I scanned the car a few weeks ago and was error free, but wouldn't you know it the car threw a code today during the pre-check. The tuner won't progress until I get it fixed as it might aggregate the fault.
I don't have any CEL or symptoms other than the code itself.
16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow
* Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80) faulty/jammed
* Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115) faulty/jammed
* Evaporative Emission (EVAP) Canister Sealing faulty
* Pipes between Tank Breathing and Throttle Body leaky/blocked
In what order should I be tackling this? N80 valve looks easy to replace so maybe I should be starting with that? If anybody has some easy checks / tests I can do (I have VCDS) to help trace it I'd be very grateful.
