Fuel light flashing

Hello all got me a 2013 jetta tdi 6speed and my fuel light flashes with fuel tank full also will flash with turn single and I have the light bulb out indicator on anyone run in to this thanks

Is there a light out? I'd start there. CAN bus systems work in mysterious ways. Hopefully you don't have furry critters chewing up the wiring.

I was thinking I may have a bad bcm or bad ground?

Could be. What light does the ecu think is out? It should tell you on the mfd. Burned out bulbs have been known to cause strange things to happen. Start with the easy stuff.
