Quick question, my volt was just in for low Freon last week and it was done on Tuesday, I picked it up Saturday and my girl saw a spot in the driveway this morning, no light is on, heat is not hissing like it was when low, is it possible just a little excess from the dealer pulling their charging hoses off?

Has it been snowing there? The combination of road salt and galvanized exhaust pipes causes a chemical reaction resulting in blue or green snow turds dropping from your car. It shouldn’t happen when driving in EV mode.

I just got home and it’s the dye from the refrigerant ! :( it looks like it’s coming from way up to of the back of the motor somewhere. So hard to see.
I’ve only heard of UV dye used in A/C systems. You can’t see UV dye without a black light.
