On May 16th, we updated all Audi S6 and S7 Stage 2 and RS turbo 4.0 TFSI ECU upgrades to version 1.2. This new version fixes reports of a “no-start” condition while attempting to first start up the vehicle. It also fixes a report of a P1335 fault code. If you don’t have either of these conditions, there’s no rush to get the update, but if you do, you can schedule an appointment with an APR dealer today. Thank you and Go APR!
