Help....
I have a 2011 q5 2.0
Today the wife said she was driving (4 miles from home) when all of a sudden the q5 felt like it was riding on a rough road. Actually hesitating. She said it seems like it will not shift above 2nd or 3rd gear. She was able to make it back home and park it in the garage.
What should I be looking for?

check engine light did come on..kinda feels like its starving for gas.
