Important Warnings and What Owners Should Know

What to Do if You Experience This Issue

If your 2022-2023 Audi displays the MIL with the Audi Q8 P240700 MIL fault, it is recommended to contact your authorized Audi dealership. While no immediate repair is available, the dealership can confirm the presence of DTC P240700 and create a Pending Service Solutions (PSS) record. This record helps Audi track the issue and ensures you are informed when a permanent solution becomes available. Do not attempt to replace parts related to the Evap system, as this will not resolve the Audi Q8 P240700 MIL condition.
