Seat Ibiza Transmission Problems

Transmission problems on the Ibiza can be tricky. Given the mileage and symptoms you describe – slipping, grinding, emergency mode – a defective control module is a definite possibility. Does the error code point specifically to the transmission control unit, or is it more general? Have you checked the transmission fluid level and condition?

The error code specifically mentions the transmission control unit (TCU). I haven't checked the transmission fluid level myself, as I understand it's a sealed unit on this model and requires special tools. Is there a way to verify the TCU is at fault definitively before replacing it, perhaps through some sort of diagnostic procedure?

Okay, the specific error code for the TCU makes things clearer. While there are advanced diagnostic procedures, they often require specialized equipment and software. Considering the symptoms and the error code, it is highly probable that the transmission control unit is the root cause. A workshop specializing in automatic transmissions will be able to confirm the problem and proceed with the transmission repair. In these cases, especially with automatic gearboxes, it's often best to get a professional opinion.

I appreciate the insight. I took the Ibiza to a local shop specializing in automatic gearboxes, and they confirmed the transmission control module was indeed faulty. Replacement and reprogramming cost me around 1000€. The shifting is now smooth again, and the error is gone. Thanks again for the input.
