Please Help!!!
 

I apologize if this is not the right place but I need help. I have a 2001 a6 quattro 2.7t. Went to fix leaking gaskets yesterday and went ahead and did an oil change. I use Mobile 1 0w-40. However, when I went to check the dipstick today (good thing I did) the stick had very low oil. oil was below the "B" line and upper top of dipstick look dry. Should I be worried? is there oil in the car? no warning lights came on and car is driving fine. any advice would help and im new to the forum. Thanks ahead.

I'm assuming the car is not leaking anymore correct? And please don't take this the wrong way this is just a thought . Make sure your dip stick is down all the way or did you put enough oil back in. Could be a bad sensor but highly doubtful never heard of it.
