06 Jetta coolant
06 Jetta, check engine light came on , got it
diagnosed. Fuel pressure regulator. Part is in the
mail.
Couple days later the coolant light starts flashing ,
but then it turns off. Also, check engine light is no
longer on although the fuel pressure regulator has
not been replaced yet. And the engine tempterature
gauge is not working now. Are these all related
things or just separate little issues.
