[I was advised] that an ATC audit revealed a discrepancy with my departure from DFW [on a flight a few weeks ago]. Upon reviewing my logbook I recalled a northbound departure; with an RNAV procedure clearance but I'm not sure which procedure. We typically are issued the TRISS departure. I was the flying pilot. I recall being issued a takeoff clearance while the preceding aircraft was still on the runway. The Captain and I agreed to delay our takeoff roll until the previous aircraft was off the runway. Climbing out on departure we experienced significant rolling wake turbulence; but did not notice any RNAV deviation. It is possible this incident created the ATC discrepancy; which we had no indication of at the time. We continued the flight without incident. Suggestions: Improved spacing between all departing aircraft. Some of the most violent wake turbulence I've experience in the MD-80 in my career has been behind Boeing 737s; which are not considered a threat. We should have reported the wake encounter at the time.
MD-80 First Officer reported being advised of a deviation on departure from DFW after the fact that may have been caused by wake turbulence encounter with preceding aircraft.
