Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“This complaint pertains to Audi's adblue (nox) system. The nox sensor failed, when the car is driving or stationary. The warning alert states the car will not start within 600 miles. The nox sensor must be replace; otherwise, the car will not run due to the software lock out triggered by the sensor. I am forced to repair the car despite the fact the tdi adblue system never worked properly as advertised by vw/Audi. In my view, vw/Audi should replace the sensor or vw/Audi should offer a reimbursement for any cost related to the tdi adblue system that occurred while the court case is pending.”
