Then after the repairs are complete make that trip again. They want us to spend 20 man hours driving, plus gas, food, and mileage. None of this is reimbursed. I have called and written Audi several times with the same answer. This is unreasonable when they have a local VW dealer https://plaincars.com/make/audi-a4 https://plaincars.com/make/audi-a4#complaint-2168248 Tue, 20 Jan 2026 00:00:00 GMT Odometer Fraud.

Initially I was told that the issue was related to an emissions sensor and that I had to drive the vehicle a few more miles to get the sensor to register properly. This turned out not to be the case. A short time later, the fuel gauge completely stopped working. https://plaincars.com/make/audi-a4 https://plaincars.com/make/audi-a4#complaint-2154163 Thu, 04 Dec 2025 00:00:00 GMT The contact owns a 2015 Audi A4.
