Seat Mii ABS light issue

I'm officially stressed. My 2020 Seat Mii electric is throwing up an ABS lamp. I've got 138350 km on the clock. The ABS system is totally kaput, and the error memory is screaming about a lateral acceleration sensor fault. From what I've gathered, it sounds like the whole control unit is defective. Anyone else had this joy? What did it cost you to fix?

Sounds familiar. I had a similar ABS lamp issue with my Mii. Did the diagnostic scan mention anything about the yaw rate or steering angle sensor? Those can sometimes be related.

Yaw rate and steering angle sensor, huh? I don't recall seeing those specifically mentioned in the diagnostic scan, but honestly, it was a bit overwhelming. How did those sensors connect to your ABS problem?

Right, in my case, the faulty lateral acceleration sensor was messing with the ABS, traction control, and stability systems. The workshop confirmed that a defective control unit can cause this. Unfortunately, it is not a cheap fix. I would recommend a visit to the workshop to properly diagnose the error.

Took it to the workshop, and the diagnostic scan confirmed the lateral acceleration sensor was faulty. Apparently, it's part of the ABS control unit. They replaced the whole unit, costing 1000€. At least the safety warning is gone and the traction control is working again. Thanks for the heads up about the steering angle issue; I'll keep an eye on that.
