VW Taigo Auto Trans Fails: Grinding, Display Dead

Recently dealt with similar symptoms on a 2020 VW T-Cross. The instrument panel issues combined with rough shifting often points to a failing transmission control module, which also affects the gear selector display functionality. The repair involved replacing the control unit and recalibrating the entire transmission system. The digital display problems were indeed connected to the transmission issues, not just a separate electrical fault. The grinding sounds you describe match what happened before the repair. This is considered a serious issue that requires immediate attention, as continuing to drive can cause permanent transmission damage. The fix needs specialized diagnostic equipment to properly code the new control unit to the vehicle. The repair process included: Full transmission diagnostic scan, Control unit replacement, System recalibration, Transmission adaptation procedures, Testing all gear selector positions, Verifying proper instrument panel function The automotive electronics needed to be reprogrammed to ensure proper communication between the transmission and the rest of the vehicle systems. Would strongly recommend getting this checked soon, as the symptoms suggest this is beyond regular maintenance. After repair, all gear selector functions returned to normal, and the transmission shifted smoothly again with no grinding sounds.

Thanks for sharing your experience with the T-Cross transmission issues. The repair process you described sounds exactly like what my Taigo needs. The gear indicator and rough shifting problems are driving me crazy. Did your car show any other sensor problems after the repair? And if you dont mind sharing, what was the final cost for fixing the control module and recalibration? My Taigo is still having issues with the gear shift and Im trying to budget for the repair. Good to know it solved the grinding noise in your case.

Thanks for asking about the follow-up details. After getting the Taigo checked by the mechanic, they found and fixed the faulty control unit, which completely resolved both the gear shift indicator display problem and the rough shifting. The total repair cost came to 1000€, covering the replacement unit and all programming work. The automotive electronics are now working perfectly, no lingering sensor issues at all. The instrument panel displays everything correctly, and the transmission shifts smoothly without any grinding sounds. The digital display showing gear positions is working exactly as it should. The repair process was thorough, with the technicians testing every gear shift position multiple times to ensure the new control unit was properly calibrated. The investment was worth it since continuing to drive with those symptoms could have led to much more expensive transmission damage. One tip: after this type of repair, its normal for the transmission to take a short adaptation period while the new control unit learns your driving style. After about a week of regular driving, the gear shift response became even smoother than before the problems started.

Thanks for the input. Just wanted to update on my Taigo situation. Finally took it to a certified transmission specialist last week. The symptoms matched exactly what was described, they diagnosed a faulty control module affecting both the gear indicator and shifting. The repair cost came to 1150€ which included the new control unit, programming, and full system testing. More than I hoped but less than I feared. The mechanic kept me updated throughout the process and explained they had to recalibrate the entire transmission system after installing the new unit. Happy to report the instrument panel is now showing all gear positions correctly and the transmission shifts perfectly smooth again. No more grinding sounds at all. The digital display is working like new and the shift knob moves through all gears without any resistance. For anyone facing similar issues, dont wait too long like I did. The grinding sounds were really stressing me out but the repair process was straightforward once I found the right shop. Now the car drives better than it has in months.
