VXR Needle Sweep
I have managed to enable the VXR Needle Sweep on my Astra Diesel speedo as can be seen in the video.
Unfortunately this isn’t possible on all speedos as the earlier ones don’t support it. It would appear that any late 2007+ car can have it enabled.
This is not the same as the “Happy Light Show” module as the needle sweep on that is only the rev & speed dials and they are not in sync. This as you can see in the video is all 3 dials perfectly in sync, exactly the same as on the VXR.
The best I have been able to do to identify which speedometers can accept the programming is a check of the circuit board by the main connector.
