Symptoms of the Audi e-tron ABS Warning P060700

Owners of affected 2021-2022 Audi e-tron vehicles may observe specific indicators related to this issue. These symptoms typically appear when the vehicle is started.

• A red warning lamp and the "ABS/ESC warning lamps light up briefly" on the instrument cluster.
• The driver might experience a "hard brake pedal" initially, which could then transition to a "soft/long brake pedal" feel.

Fault Codes / DTCs

When diagnosing this condition, technicians will find a specific Diagnostic Trouble Code (DTC) stored in the ABS/ESP control module, identified as J104 (address word 0003).

Code	Description	Module
P060700	Control module malfunction	ABS/ESP (J104)

This DTC P060700 indicates that the control module itself is reporting an internal malfunction.

Technical Background and Trigger Conditions

The root cause of the Audi e-tron ABS warning P060700 lies in the ABS control module's basic setting cycle. This cycle is designed to run during the vehicle's shut-down procedure after the ignition is switched off. However, certain conditions can prevent this cycle from completing successfully.

The primary triggers include:

• Low voltage: Insufficient electrical power can disrupt the control module's operations.
• Brake pedal activation: Pressing the brake pedal while the ignition is being switched off or as the control module enters sleep mode can interfere with the basic setting process.

When the basic setting cycle fails to complete, the vehicle's system attempts to re-perform it upon the next start-up. The illuminated warning lamps signify that the "brake-by-wire function is currently unavailable".

Important Warnings

Owners should be aware of the following critical information regarding the Audi e-tron ABS warning P060700:

• Mechanical Braking Still Functional: Even when the "brake-by-wire function is currently unavailable", mechanical braking operation will still function. This means the vehicle can still be stopped safely using the brake pedal.
• Temporary Condition: The normal brake-by-wire operation is restored after the brake pedal is released and pressed again. This indicates the issue is often transient.

Repair Procedure Summary

The resolution for the Audi e-tron ABS warning P060700 is straightforward. Technicians are instructed to:

1. Connect to the vehicle's diagnostic system.
2. Clear the stored Diagnostic Trouble Code (DTC) P060700 from the ABS/ESP control module.
3. Release the vehicle back to the customer after confirming the DTC is cleared and the warning lamps are off.

No specific parts replacement or complex repair steps are outlined in this bulletin, as the issue is primarily a software or system state anomaly.

What Owners Should Do

If you experience the Audi e-tron ABS warning P060700, particularly the brief illumination of ABS/ESC warning lamps or changes in brake pedal feel, it is recommended to:

1. Observe the behavior: Note if the warning clears after releasing and re-pressing the brake pedal, as the system is designed to restore normal brake-by-wire operation under these conditions.
2. Contact your Audi dealership: While mechanical braking remains functional, it's best to have the vehicle diagnosed by a qualified technician. They can confirm the presence of DTC P060700 and clear it according to this Technical Service Bulletin.
3. Inquire about warranty coverage: As outlined in the warranty section, this repair may be covered depending on your vehicle's age and mileage.
