Bumper dent repaired... now no ultrasonic (proximity) sensors :(

[mcfuzz89]

I got a dent on my front bumper which I got repaired.

When I got the car, I noticed the AC was blowing on my feet instead on me and that my external temperature was not working. Figured it had something to do with the Tesla being a Tesla and that it'd fix itself. It did not. Not even after soft/hard reboot.

I also then noticed my front and rear proximity sensors did not work and auto lane change did not work either with an alert appearing indicating "ultrasonic sensors not communicating" - uh oh.

Took the frunk cover off but could not find anything disconnected. Poked under the bumper but you can't see crap there.

I guess I will be calling the shop on Monday and perhaps Tesla service too. I heard that a single disconnected/faulty sensor could cause that but - I did not observe anything disconnected.

Any ideas of what else it could be?

Thanks!

Disconnected sensor or wire harness damage.

Hm. Ok - I will go through the sensors again tomorrow. If it is wiring harness damage... shop is gonna pay through the nose!

Was it a Tesla certified body shop?

It was not. I figured since the bumper did not require replacement, I could easily go to any shop - here in the bay, everyone works on everything but if they know things require replacement, they turn you away haha

If you don't know what you don't know, it's all good

Bringing into sc and have them take a look.

I'd run a level 3 diagnostic on the forward sensor array immediately.

How do you do that?

How do you do that?

With a reverse-polarity tachyon field phase scanner, of course!

...and a Johnson rod.

The plug for the main bumper harness is under the passenger side headlamp. Remove the clips for the liner and pull it to the side and look. It will be hard to get to, but if its unplugged you'll see it hanging.

The shop that did your work should fix it.

So interesting development - without me doing anything, overnight half the sensor started working. Looks like the rear and front driver sides are online but passenger and center may are not working still. Also no proximity chimes.

Temp sensor still offline; remote AC worked ones and so did the "leave AC running after parking" feature - but only once; now it is back to being grayed out.

I will remove the frunk in a bit and see check things out! If I can't figure it out - then yeah, going to the shop tomorrow.

Update:

Yup - main sensor harness was disconnected. Reconnected and voila! Everything works!
