So I got a Left Rear ABS Sensor error, which causes all sorts of things to not work on the 500e, no Regen, no Hill Hold, no ESC, and of course, no ABS. Other than that the car drives exactly the same. So I went and bought a new ABS sensor, and installed it on the left rear. And I still have the error. I used AlfaOBD to show the sensor at work, and it definitely shows an error. So my question is, would the left and right possibly be reversed, like the brake light message?
