I'm pretty sure it's not the ETC now as I've removed the card reader and the windshield sensor.
The beeping is not like any other noise the car makes (attached m4a). It's like a 90s midi mobile phone beep. And always three beeps on start up and every 60-90 seconds. It almost sounds like it's coming from between the head unit and dashboard display.

Not difficult, remove a couple of screws from black cover under the drivers footwell.
Remove the plastic kick panel on the right side, held on by one plastic thumbscrew.
You'll reveal a few screws holding the lower dash panel, undo, and pull from the door side, you'll see the etc unit, disconnect the larger plug that powers it.
Hey thanks for this. Really straightforward instructions. I removed the ETC unit but I still get these three irritating beeps on start up and every 90 seconds or so. Do you reckon I've gotta disconnect the sensor on the windscreen as well?

After another poke around i found the beeping: the electronic damping force controller! Turned it off and finally got rid of the noise 😂
