2007 A3 Wiper Reservoir
 

Moved to Salt Lake City, Utah about 5 months ago, just in time for some serious snow. Long story short I managed to catch a road marker in the snowy conditions and took out the right front fog light. The bumper is cracked and now my windshield washer reservoir won't stay full. I took the attached and think I am missing some sort of plug as the grommet is probably intended to house a pump for headlight washers, which I do not have. I am trying to locate the plug.




Can any one help?

Thanks
