Tomorrow morning we will use the car again for a log drive that will empty the battery for sure and then Iĺl charge it again. Will keep you updated on the progress! Thanks so much for your help already!

Thank you
Your car and subscription are fine — the app was reading 94 fields and 36 values right before this started. Two problems on our side, both fixed in the next version:
The app gave up on a request after 30 seconds, but the portal legitimately takes up to 28 — so when it got slow, everything failed. Now 60 seconds.
And tapping refresh while a poll was running started a second one, and each failure doubled the retry delay separately. So pressing refresh repeatedly made the wait longer. Also fixed.
Until then: leave it alone for half an hour rather than retrying — the backoff resets itself as soon as one poll succeeds.
Thanks it started working in one hour after i posted my issue. thanks. keep the good job..
Hi @Andi,
I’ve followed all the instructions and the connection it seems to be OK.
But I get no data… even after a day. Or… I get data but “empty”.
Any idea why?

As there is no data in the zip file I recommend contacting them directly: VW Group EU Data Act Portal via e-mail: euda-support@cariad.technology
I have the same issue and am awaiting a message back from VW Group. There might be a glitch in the service?
Can you please share it when you will have it?
I got the below back from cariad about 10 days ago.
“We have identified a bug associated with the issue you are experiencing. At this time, we do not have an estimated time for resolution (ETA) from our engineering team.”
Hi there! I would love to see and use mu ID4 car data. I installed the app, activated sharing data in my car and did everything needed on the eu-data-act site. I asked for continuous 15 min delivery of data sets.
Unfortunately, still Homey does not report any data. What can i do?
They replied:
Hello,
We wanted to provide you with an update on your ticket.
Current Status:
The issue has been reviewed by the VW GIS Support Team and requires additional expertise for resolution. The ticket has been escalated to the team for further investigation.
Next Steps:
The team will continue the investigation and provide updates. We will monitor progress and keep you informed as new information becomes available.
If you have any additional details that might help the investigation, please reply to this message so they can be included in the escalation.
Thank you for your patience and cooperation."
Have you checked the actual data packages on the data act portal? If they are empty please report it. There are several people experiencing empty packages and there seems to be a bug on the Cariad end. If many report the issue it might be prioritized.
I can’t get it to work for my Cupra Born, I just get no_content_found packages. Because I tried all your suggestions several times, the last thing I could do is ask Cupra Connect Customer Services for a solution. They responded as below. Can you help me out?
Thank you for contacting us.
To enhance security, protect customer data, and improve the stability of CONNECT services, CUPRA Charging has implemented Control Attestation.
This security measure restricts access to charging-related services and only allows officially authorized partners to connect to the secure interfaces.
Since the app you are using is not an official CUPRA product, we unfortunately cannot assist you regarding its operation.
We kindly recommend that you contact the app provider directly for further support.
If you have any further questions, please reply to this email. Please make sure to include your case number 00634015.
You can also reach us via:
Email: cupradigitalsupport@cupraofficial.com
Phone: 00800 6000 40 20
i sent a message on https://eu-data-act.drivesomethinggreater.com/ to VW to ask for a solution.
If the packages are empty, reach out to cariad through the eu data act portal to create a ticket.
Thanks, did that and waiting for response now.
This is what I got back from EU Data Act Support:
Dear User,
We would like to inform you about a known issue that may have affected your recent vehicle data download request.
Due to a technical problem, some users currently receive a download file containing the message “No Content Found” instead of the requested vehicle data.
Our engineering team is actively investigating and resolving the issue. We are treating this with high priority and are working to restore normal service as quickly as possible.
There is no action required from you at this time.
We will proactively notify you once the issue has been resolved and your data export can be successfully retrieved again.
We sincerely apologize for the inconvenience and thank you for your patience and understanding.
Kind regards,
EU Data Act Support
Volkswagen Group Info Services AG
I have the same issue. Get no_content_found on my two VW Vehicles, and have had that, since they were created almost a week ago. Played with the same data-transfer system some months ago, and it was working fine back then.
Here the problem was suddenly solved. I think the mail to EU-data did the trick.
Same here - working now. Thanks for your efforts!
