Saas nähä, miten tuo menee Suomessa
Dear ID. Community,
In recent weeks, we have received an increasing number of inquiries regarding warning messages in connection with the eCall. We would like to inform you that we are in continuous coordination with the relevant departments to ensure clarity and transparency.
What happened?
The Online Connectivity Unit (OCU) establishes the connection between the vehicle and the backend. It is equipped with a backup battery to ensure the eCall functionality for up to one hour in the event of the OCU being disconnected from the 12V electrical system, for instance in the event of an accident with impact on the 12V battery.
The state of health (SoH) of the backup battery is continuously determined by periodically measuring various battery parameters.
The ID. Software 3.8.1 update overwrites the measured SoH, causing the algorithm to fall back to a fixed replacement interval of 5 years.
The result: regardless of the actual condition of the battery, affected vehicles whose OCU backup battery is approaching an age of 5 years will display a warning message, which leads to replacement of the backup battery.
What is Volkswagen doing to help me with this?
→ We have heard and carefully analyzed your concerns.
→ The topic has been well analyzed and measures have been defined in alignment with the relevant partners to replace the backup battery. These have been thoroughly communicated to our importer network.
→ In parallel, we are working on a software-based solution to re-establish the actual SoH-measuring.
→ To support transparency and address the most common questions, the following FAQ has been prepared.
--- FAQ ---
What should I do if the warning message appears?
Affected customers are asked to take their vehicle to a workshop to have the backup battery/SOS module checked and replaced, if necessary.
Who covers the costs?
Volkswagen will cover the costs for the replacement of the backup battery through its authorized service partners.
What if parts are not available?
We are currently experiencing delays in the delivery of backup batteries. According to our logistics partners, the situation should improve and stabilize in the coming weeks. Please rest assured that we are doing our best to improve the supply situation.
Can I resolve this using my OBD11?
We do not recommend these diagnostic routines. Such steps cause the algorithm to assume a new battery with 100% health status has been installed, making subsequent measurements inaccurate. In the worst case, this could lead to a significant decrease in capacity over time, so that in an accident where the 12V battery is damaged, an emergency call might be interrupted due to insufficient backup battery capacity.
My workshop seems to be handling this poorly. What can I do?
Our importers were informed some time ago and our service partners have access to reliable information. While they have no influence on delivery dates either, we are aware of some complaints regarding the handling of this matter. If you feel affected, please contact your local customer care and explain the situation. The ID. Drivers Club team discusses all complaints with the responsible departments, but we are legally not permitted to contact or instruct any service partner directly.
Where can I find more information?
We have tried to answer all questions in this post. If you have further questions, please do not hesitate to ask us in the comments.
Best regards,
Your ID. Drivers Club Team
