Is it possible to install a radar sensor myself on a "no radar" Model Y/3

Not sure how up-to-date the site is but it's interesting to read...

Please do not use that on public roads. There are other cars around you.

Mobile service wouldn’t do it. I got root and did it myself lol

How has this been working for you? Considering doing the same. How is the process of getting root and enabling it? Does it last when new updates are installed?

Thanks!

Works great, love 90mph and the very smooth tracking.

It lasts forever

DM me if you want to try it

Yeah its like night and day (except when using fsd beta)


Yes


Yup with FSD beta the +5 limit is removed on local roads, but you're capped to 80mph on highways and 2 car follow distance

Fascinating, are you the only known person to have done this? This seems like a brilliant hack, I'm eager to try. What resources did you all use to do this? If you made a guide somewhere I bet you could get a lot of interest.

Hey I don't know how to DM you. I might not have permissions because I'm not active enough or something. But I was wondering if you know the answer to my question - my model 3 has the "reduced front radar visibility" problem which I believe is due to a faulty radar. I bought a new one from ebay with part number 1108647-00-b but mine is actually supposed to be C or D (i forgot which one) and when I installed it on the car it wouldn't even recognize a radar was plugged in. I switched back to faulty radar and it recognized it but had the visibility error again. So my question is: is there some configuration that tells the car to ONLY work with a specific radar? Or will it work if i just buy the one with matching part number.

Installing a software update from Tesla MIGHT enable it, but there's a good chance that you need a technician to run a script to wed the radar to the VIN.

I made a rough guide somewhere in my posts, requires some disassembly/hacking though. Tesla could easily allow people to change this with Toolbox but for some reason they choose not to.

Pretty sure the last letter -B/C/D are generally just part revisions which are pretty interchangeable, so it should work. Issue is often that if you plug a radar it in spits out garbage data until you reset it in toolbox (relevant tasks are in the guide i wrote and available with the $300 toolbox subscription). An update may pair it as @smatthew noted but its not guaranteed. To minimize garbage data risk, its advisable to update it just after plugging it in. Mine was installed for a few days before updating, and i had garbage data issues.
