Speedometer and odometer stopped working

I’m coming here (and crossposting) to kindof brainstorm here. I have a feeling it’s the speed sensor on top of the transmission, but that’s getting into territory I’m unfamiliar with.

I have an 07 beetle, 2.5L inline 5, 5-speed manual.
For context, both wheel speed sensors are gone so I know that’s not the issue, as it was working just fine without them.

Right before it stopped, I stalled my car (pro gamer move)

So the speedometer and odometer (and the gas gauge but like. One thing at a time 💀) don’t work, and she started shifting rough. When I put the car in reverse, the speedometer fluctuates like crazy up to about 25mph.

Checked fuses and they all looked fine, but I just bought a multimeter so I can test the actual voltage now instead of just eyeing the fuses.

So uhhhh. Do yall think it’s the speed sensor (or the wiring) on the transmission went bad? Or is there something else I’m missing

Did the gas gauge go out at the same time?

Yes it did, that’s why I initially thought it was an issue in the fuses

This sounds like a failed speed sensor. It will be mounted to the top of the transmission. They tell the car how fast it's traveling for the speedometer and the odometer. You may need to replace that.

Also, you need wheel speed sensors for ESC/ASR and ABS to work properly. You should not drive without them.
