Recently bought this 06 RR... ran fine for about a week then started acting up. If I can manage to start it, it won’t start back up for another couple of days. I have videos of the instrument cluster and the craziness that it’s been doing, hopefully they post

 

Hey Austin, could you post the link to the video for a better look?

 

Here’s the first one showing what the instrument cluster does

 

It has the appearance of the ECU losing connection and going through it's power up cycle. I'd check the connections on the ECU and make sure they're seated properly. Then check the connections to the gauge cluster as well. Again, making sure they are properly seated.
