Experiencing sudden fault lights and cruise control disengagement in your Audi A6? A VCDS scan can reveal a wealth of information, often pointing to issues with the parking brake system. This guide delves into understanding and addressing “Audi A6 Parking Brake Vcds” fault codes.
A recent driving incident resulted in multiple fault lights illuminating on the dashboard of an Audi A6 (C7) and disengagement of the cruise control system. A subsequent VCDS scan revealed numerous fault codes across various modules, including a significant malfunction within the parking brake system.

The specific code, U1113 00 [137] – Function Restriction due to Faults in Other Modules, suggests that the parking brake issue might stem from problems in other interconnected modules. This often indicates a communication error on the CAN bus.
Further analysis of the VCDS scan reveals faults in the ABS system (Address 03) and related modules, potentially contributing to the parking brake malfunction. The ABS system and the parking brake often share sensors and communication lines. An ABS sensor fault, specifically a wheel speed sensor issue (code C101B 07), is identified. This malfunctioning sensor could disrupt signals relied upon by the parking brake system.
Resolving the underlying ABS fault, specifically the faulty wheel speed sensor, is the recommended first step. This might involve sensor replacement or addressing wiring issues. Clearing the fault codes after the repair and re-scanning with VCDS will confirm if the parking brake issue has been resolved. If the parking brake fault persists, further diagnostics within the parking brake module itself will be necessary.
