Repair Procedure Summary

For the Audi P240700 MIL issue, Technical Service Bulletin 01 23 99 2066675/6 outlines a specific, temporary procedure for technicians to follow:

1. Delete DTC P240700: The primary step is to clear the Diagnostic Trouble Code P240700 from the vehicle's Engine control module. After clearing, the vehicle can be released back to the customer.
2. Customer Communication: Technicians are instructed to inform the customer that a permanent solution is anticipated by the end of the second quarter of 2024.
