Hello there, bought my daughter a very nice 1 owner B7 A4 Quattro S-Line. Beautiful car well maintained by the previous owner. We’ve owned for about 6 months now and recently started having some fuel issues. It started with the gas marker not working properly. Recently i started to have power loss. I would accelerate and the car had no power. Bogging and shaking at stop lights. I barely made it home. Today after a week I turn on the car and it’s perfectly fine. Turn right on, drove it around for about 20min. I do have these two codes. And car smells tons like gas. I had to take it out of my garage. I don’t hear the fuel pump priming when I open the door anymore. Any help would be appreciated, thanks in advance. 192k miles on ithttps://uploads.tapatalk-cdn.com/20240824/44e30f127729b1d6082aa9525f2ebeb6.jpg

With all of the "Short to Ground" notes for for the codes, I would start looking for wiring loom issues.

Following. Actively troubleshooting a similar short to positive/intermittent code for N276 sensor.

Looking back at it I have several O2 sensor short to ground codes as well and a ECM power relay switch short to ground. Any tips on where I should begin my search for this short? Thanks in advance

Check ECM tray for water ingress. Drains in battery tray get clogged and there are several relays in the ECM tray
