2021 Audi A6 Drive System Fault P060600 TSB

Audi has issued Technical Service Bulletin (TSB) 01 24 32 2074841/1, dated August 9, 2024, to address a specific drive system fault affecting certain 2021 Audi A6 vehicles equipped with the 4-cylinder 2.0-liter TFSI engine. Owners may notice a "Drivers System fault on" message appearing in their vehicle's display.

This condition is linked to event memory entries logged in the engine control unit J623, also known as the Engine Control Module (ECM). The TSB outlines the necessary steps to resolve this issue through a software update.

Symptoms of a Drive System Fault

The primary symptom reported by owners is the illumination of a "Drivers System fault on" message. This warning indicates a general issue within the vehicle's drive system that requires attention. If you own a 2021 Audi A6 and see this message, it's important to have your vehicle diagnosed.

Diagnostic Trouble Codes (DTCs) and Fault Labels

When a "Drivers System fault on" message appears, a workshop diagnosis will likely reveal one or more of the following diagnostic trouble codes (DTCs) stored in the ECM J623 (address word 0001):

DTC Code	Description	DFCC
P060600	"Engine control module faulty"	15139
P060600	"Engine control module faulty"	40258
P060C00	"Engine control module internal system failure"	30794 and/or 37379
P0A0F00	"Engine does not start"	38653

These codes specifically point to issues with the engine control module, ranging from general fault conditions to internal system failures or an inability for the engine to start. The presence of these codes, especially P060600, confirms the need for the prescribed repair.

Why This Happens: Technical Background

The root cause of the 2021 Audi A6 drive system fault P060600 and related DTCs is identified as outdated software within the Engine Control Module (ECM), unit J623. New software has been developed and implemented in production to address this specific condition.

The Repair: ECM Software Update

To correct the drive system fault, the software in the ECM J623 must be updated. This update is performed using the Software Version Management (SVM) system. Technicians are instructed to follow the guidelines provided in TSB 2011732, which details the SVM operating instructions.

The update involves using SVM action code 01A267 to flash the ECM. The old software part number 4K0906259A, with versions such as 0005, 0007, or 0009, will be updated to the new software version 0011 for the same part number.
