Other Issues from Audi's Analysis List

This comprehensive analysis list also highlights several other potential concerns for various Audi models:

• Corrosion on Wheelhouse Cover Plate: Affecting 2017-2019 Audi Q7 and 2019 Audi Q8 models. Diagnosis requires various photos and inspections as detailed in an associated worksheet.
• Roof Panel Buttons Inoperative: For 2022-2024 Audi Q4 e-tron models, the dome light buttons may be unresponsive or come on without input. Sunroof buttons may also be unresponsive, often in conjunction with the dome light issue. Refer to associated worksheets for instructions.
