AdBlue warning light

Hi. My 2009 Q7 has an AdBlue low warning light. "No restart in 600 miles".
The AdBlue tank is full. I just filled it with 5 gallons. Full to the top. Is there a rest light option on the VCDS?

. If you are adding Adblue due to a low level light, you must add at least 1 gallon and you must wait a little over 30 seconds after turning the ignition ON before starting the engine. Otherwise the light can stay on.

I hope this helps.

I hear tell there is talk about getting rid of DEF, as toooo many problems with it in the diesels big and small. We see
