If you definately have a sensor that tested bad , let’s wait to replace that before we work up the signal chain .
The front 2 sensors are the same , should you wish to swap whilst waiting for a replacement .
Another quick check while you have a repeatable fault , if you can please try to pull over and starting in neutral after a tip fault .
The good news is , you have a repeatable fault !!
Much easier to troubleshoot than an intermittent fault …
Next step would probobly be the speedo converter , as that takes a wheel speed sensor and converts to speedo signal . Speedo then controls spoiler through spoiler control unit .
If the converter is bad you lose speedo , and everything it controls .
You should find the speed signal converter in the front fuse box iirc
