2001 Audi A6 Quattro Avant 6 Cyl 2.80L
What causes the engine light to pop on and off
Seems there is a little stall n the engine when I reach 80 mph
Have the check engine light (CEL) scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply with the specific fault code for more assistance.
