We have a 2017 Beetle, 42k miles, just purchased used. We had it checked by AAA mechanic and he overlooked one relatively minor problem. The gas nozzle at pump will not stay on any more than a few seconds at a time. It keeps shutting off long before the tank is full.
I understand it is something wrong with the evaporation recovery. Plugged vent or faulty canister. Cannot find much guidance on where the vent(s) are located and how to access &/or replace the control cannister.
Any help/advice is much appreciated.
