Hello In my case (sporadic EVAP system failure), after 15 visits to the workshop, the first in August 2023 and the last in October 2025, apparently the problem is solved. They told me it was a defect in the tube (nº 3 in picture) that goes from the N80 valve to the activated carbon filter. After changing the entire tube, from the filter to the valve, and about 6000km driven, the problem did not happen again. I hope it's resolved. Meanwhile, another problem has arisen: the battery does not charge above 95%... Tired of this car!

Hello In the US, there's a technical note (safety recall) about water ingress at the Gateway. I don't know if it's available in Europe, but it's worth checking with your dealer. Audi TSB 90S9 Gateway Water Ingress.pdf

Hi Try the attached instructions. They are fom the pre-facelift workshop manual. A-Pillar removal_1.pdf

Hello. Thank you for your reply. Although the problem is the same, the origin must be different, since the car always gives an EVAP system error, and I never turned off the intelligent coasting system. Tomorrow it will go back to the garage. Let's see what the "project" for a solution is this time. Luckily, I bought an extended warranty when I bought the car, so I still have the warranty until October 2026. I hope that is enough time for the Audi technicians to find a solution... Best regards

Thank you very much.

Thank you very much for your reply. Audi dealership is trying to solve this problem since october 2023. After the diagnosis they find error P044100 - EVAP emission incorrect. The solution was to change N80 valve, but the problem came back! Every 2000km, more or less, the problem returns and i have to stop the car, shut off engine and restart the car so that the system works normally again. I went back to the workshop more than 10 times and they changed practically everything in the EVAP system, but without success. Next appointment at the dealership will be on the 11th. I'm curious about what they'll replace this time...

Hi Same problem. Any update about the solution? Thanks
