Help Needed: Persistent DQ381 Gearbox Issue in Seat Ateca

Hello everyone, I'm experiencing a problem with my Seat Ateca's DQ381 gearbox. The transmission indicator light comes on, and I'm also getting a POC2900 error code. I've already changed the pump and checked the wiring, but the issue persists. What else should I investigate to resolve this problem? Any advice would be greatly appreciated!

Check the transmission fluid level and condition, as low or contaminated fluid can cause issues. Make sure it's at the correct level and replace it if necessary. Let me know how it goes or if you have any further questions!

Ensure that the new transmission is properly programmed and calibrated to your vehicle's ECU. Mismatched software or incorrect adaptation can lead to persistent error codes. If you're unsure, it might be best to have a professional perform this task. Let me know if this resolves the issue or if you have more questions!

Yes, after replacing the pump, it's important to calibrate or program it to ensure it functions correctly with your vehicle's system. This can often resolve error codes like POC2900. If you haven't done this yet, I recommend having it calibrated by a professional. Let me know if this helps or if you have any further questions!

For the DQ381 transmission in a 2017 Seat Ateca, the software version can vary based on the specific model and region. It's best to check with a Seat dealership or a professional with access to the latest technical service bulletins for the exact software version required for your vehicle. They can provide the most accurate information and update the software if necessary. Let me know if you need further assistance!
