Condition
This Update has been proactively released to prevent the following condition from occurring in the vehicle:
The MIL is on for steering related faults.
This Update is in effect until removed.
Vehicle must meet all of the following criteria:
• Procedure is valid only for vehicles that show the 48K4 code in the ElsaWeb Campaign/Action Information
screen on the day of repair.
• Vehicle must be within the New Vehicle Limited Warranty.
• Procedure must be performed within the allotted time frame stated in this Technical Service Bulletin.
• Procedure must be performed on applicable vehicles in dealer inventory prior to sale.

Technical Background
On Audi vehicles with electromechanical power steering manufactured within a specific period, an irregularity
detected by the diagnosis function can result in an implausible status immediately after the engine is started. This
causes the warning lamp for the electromechanical power steering to light up. There is no loss of steering
functionality.

Production Solution
New software in the power steering control module (J500) addresses the condition.
