I had a mechanic shop install. Rear coil spring spacers to lift the car. They’re from tema4x4. Car drove fine, and then all of the sudden the blind spot assist becomes unavailable, the car goes into limp mode, steering tight, little throttle, and ABS and traction control lights are on. Check engine light comes on and I’m getting codes for all four speed sensors. Is this related to the air ride in the rear?

The speed sensors appear to be fine, although they were disconnected while installing the spacers. If I turn the car off and back on, it runs fine. Drive some more and it’ll do the same thing. The speedometer also falls to 0.
