Seat Cordoba ABS and Traction Issues

I had a similar issue with my Cordoba. The ABS light kept coming on, and I was getting some weird readings from the transmission. Have you checked the wheel speed sensors? Sometimes a faulty sensor can cause the ABS system to go haywire. Also, did you run any diagnostic codes to see what's triggering the light on the dashboard?

Thanks for the quick response! I did check the wheel speed sensors, and they seem to be functioning correctly. I also ran a diagnostic, and it's pointing towards a speed signal fault. Could you elaborate on the 'weird readings from the transmission' you experienced? Was it also related to the speed signal?

Yep, the weird readings were definitely related to the speed signal. The diagnostic pointed towards the ECM being the culprit. If the sensors are fine, and the diagnostic indicates a speed signal fault, then a defective control unit is the most likely cause. I'd suggest taking it to a workshop; they can confirm the diagnosis and replace the faulty unit. It's not a cheap fix, unfortunately.

Took it to the workshop as you suggested. The ECM was indeed faulty. After replacing it, the ABS light is gone, and the traction control is working perfectly again. Cost me around 1000€, but it's worth it to have the car running safely. Thanks for the help!
