Backstory:
I got bmw performance struts and h&r sport springs. Installed the backs 2 weeks ago, got really busy and had no time to finish the fronts. Had a friend do the fronts at the shop on Tuesday. He drove my car back to me, I drove it to the other office, on the way home, I get the brake light, the abs , the dtc and also tmps light. Now I dont have tmps sensors in my current wheels but I didnt have them on my 19s too and I never got an error. I called the friend to see if he had any issues with the install, he said everything went smooth but before he started one of the sensors on the right side was hanging out of the box it sits in.
When I got home, I jacked it up and saw that the sensor was hanging loose again, I put it back in the box that it sits and its been fine, I checked the wire and all seems fine.
I searched here and saw that a few people had issues like mine after a suspension install and it was caused by a bad alignment , so I had my alignment done today, I also tried resetting the steering wheel sensor before and then after the alignment with my BT cable with no avail.
So with the alignment out of the way I'm back at square one. I'm thinking its the wheel speed sensor but I want to make sure before I buy one because I inspected the current one and it looks fine, plus the car made 2 15 min trips after the install was done before the errors came on.
Is there anyway to tell if the wheel speed sensor is bad other than physically checking it for issues?
I also read the steering sensors in the early build date models might go bad, it seems weird that the car is freaking out now where I had coilovers on it before and it was much lower and the alignment was even more off and I never had any issues.
I also read that there is a ride height sensor on the right front of the car, I want to make sure nothing got ripped out by accident, comparing both sides of the vehicle, the drivers side has 1 brake line and 2 wires running from the hub, etc to the plastic box. The passenger side ONLY has 1 brake line and 1 wire? Is that correct , is there another sensor that goes there too, if so what is it lol because mine is missing?
Thanks in advance.
