2021 Audi A6 Jerking/Hesitation with DTCs P010600, P023600

Owners of the 2021 Audi A6 may encounter issues such as the vehicle jerking, bucking, or hesitating during driving, along with a noticeable loss of power. These symptoms are often accompanied by the illumination of the Malfunction Indicator Lamp (MIL) on the dashboard. This problem is linked to specific diagnostic trouble codes (DTCs) that indicate a fault in the engine's pressure sensing system.

Why This Matters

The 2021 Audi A6 jerking hesitation issue stems from a damaged yellow wire on the electrical connector for the G31 charge pressure sender. This damage is typically caused by vibrations due to the original routing and uncovered length of the wiring harness. A compromised connection at this sensor can lead to incorrect engine management readings, resulting in the described performance problems. Audi has since implemented a production solution to secure the harness with textile tape, preventing this issue in newer vehicles.

Symptoms

If your 2021 Audi A6 is affected, you might observe the following:

• The vehicle feels as if it is "hesitating" while driving.
• A sensation of "low on power" or "bucking/jerking" during acceleration or steady driving.
• The Malfunction Indicator Lamp (MIL) may be illuminated on your instrument cluster.

Fault Codes / DTCs

When diagnosing this issue, technicians may find one or more of the following diagnostic trouble codes (DTCs) stored in the Engine Control Module (ECM), specifically J623 (address word 0001):

Code	Description
P010600	Manifold Abs.Pressure or Bar.Pressure Range/Performance
P023600	Turbocharger Boost Sensor (A) Circ. Range/Performance

Important Warning for Owners

Audi has issued a crucial warning regarding this issue: "Parts replacement does not solve this issue. Claims for replaced parts (e.g. G31 sensor or turbocharger) will be subject to review." This means that simply replacing the G31 sensor or the turbocharger will not resolve the underlying wiring problem and could lead to unnecessary costs. The focus should be on repairing the damaged wiring harness as outlined in the Technical Service Bulletin 2062323/1.

Repair Procedure Summary

To address the 2021 Audi A6 jerking hesitation and associated DTCs, the repair involves inspecting and repairing the wiring at the G31 boost pressure sensor. Technicians will first check the wires at the G31 connector for any damage, particularly the yellow wire. If damage is found, the harness will be repaired using specialized tools and gold-plated contacts to ensure a durable connection. It may be necessary to disconnect or de-pin the wires from the G31 connector to properly check for crimping and seating of the pins. After repairing the damaged wires, sufficient slack must be ensured in the harness to prevent future issues. Finally, the harness is wrapped with textile tape, starting below the connector and extending to cover the connector base, to secure it against vibrations.

Owner Action

If your 2021 Audi A6 is exhibiting symptoms of jerking, hesitation, or low power, especially if the MIL is illuminated, it is recommended to schedule an appointment with an authorized Audi service center. Inform them of the symptoms and mention Technical Service Bulletin 2062323/1. Ensure that the service center focuses on inspecting and repairing the wiring harness at the G31 sensor, rather than immediately replacing components like the sensor or turbocharger, to correctly address the root cause of the 2021 Audi A6 jerking hesitation.
