Experiencing ABS and stability control issues in your Volkswagen Golf 2011 Tdi after a battery disconnection? It’s a common problem that can leave you with flashing warning lights and a rejected coding error when trying to rectify it. Let’s delve into understanding this problem and explore potential solutions.
It appears you’ve encountered a situation where the ABS module coding was lost on your Volkswagen Golf 2011 TDI after an extended period without battery power. Using diagnostic tools like VCDS, attempts to recode the module have been unsuccessful, resulting in a “coding rejected, Error 31 request out of range” message. This is frustrating, especially when dashboard lights are persistently blinking.
Based on the provided VCDS scan data for your Volkswagen Golf 2011 TDI, several fault codes point towards communication and sensor issues, particularly within the braking and steering systems. The key ABS Brakes module (Address 03) shows “Control Module; Not Coded” and “No or Incorrect Basic Setting / Adaptation” errors for Brake Pressure Sensor 1 (G201), Steering Angle Sensor (G85), and Lateral Acceleration Sensor (G200). These faults often arise together when the ABS module loses its coding or requires basic settings to be re-established.
Furthermore, the scan indicates communication problems with other modules like Cent. Elect. (Address 09) and Central Conv. (Address 46), along with faults in Steering Assist (Address 44) and Information Electr. (Address 5F). These may be secondary issues triggered by the primary ABS coding problem or independent concerns that require attention.
Possible Steps to Resolve the ABS Coding Issue on Your Volkswagen Golf 2011 TDI:
-
Verify Battery Condition: Although seemingly obvious, ensure your battery is fully charged and in good health. Low voltage can sometimes cause communication and coding issues within vehicle modules.
-
Correct Coding: The core issue is the lost ABS module coding. Obtaining the correct, specific coding for your Volkswagen Golf 2011 TDI is crucial. This coding is not universal and depends on your vehicle’s exact specifications and factory equipment.
- Ross-Tech Wiki & Forums: As you initially did, Ross-Tech forums and Wiki are valuable resources. Search specifically for “Golf MK6 ABS coding” or similar terms. Sometimes users share coding strings or procedures that might be relevant.
- Volkswagen Dealer: Your local Volkswagen dealership can provide the correct factory coding for your VIN. They can access the official database and give you the precise coding string needed for your 2011 Volkswagen Golf TDI ABS module.
- Online VCDS Coding Databases: Some online databases (often community-driven) may contain VCDS coding examples for various VW models. Use these with caution and verify the source’s reliability.
-
VCDS Recoding Procedure: When you have the correct coding, use VCDS to perform the recoding process. Ensure you are following the correct procedure for ABS module coding in VCDS. Double-check all steps and input the coding string accurately.
-
Basic Settings and Adaptations: After successful coding, it’s highly likely you’ll need to perform basic settings and adaptations for the Brake Pressure Sensor, Steering Angle Sensor, and Lateral Acceleration Sensor, as indicated by the fault codes. VCDS has guided procedures for these adaptations within the ABS module section. Follow these procedures meticulously.
-
Clear Fault Codes: After coding and adaptations, clear all fault codes in the ABS module and any other modules that showed communication errors.
-
Test Drive and Rescan: Perform a careful test drive to see if the warning lights are gone and the ABS/ESC system is functioning correctly. Rescan the vehicle with VCDS to confirm that the fault codes are cleared and no new ones have appeared.
If you continue to experience “Error 31” or coding rejection despite using the correct coding and following the procedures, there might be an underlying issue with the ABS module itself or the communication network in your Volkswagen Golf 2011 TDI. In such cases, seeking assistance from a qualified automotive technician with experience in Volkswagen diagnostics and ABS systems is recommended. They can perform deeper diagnostics and pinpoint the exact cause of the coding problem.
