I stepped on brake which slowed my vehicle but when I removed foot from brake it started to accelerate again. I was able to exit freeway safely and pull over into an empty parking lot. When I turned off engine I believe I hear a loud "roar" noise. Experience was frightening. I was afraid I would lose control of vehicle and cause major injury. I checked floor mat and floor to see if there was obstruction but there was none. I called tow company but after waiting 3 hours for c&m towing to not show up I decided to driver car around parking lot to see how it would drive. It drove fine so I drove home on surface streets. The next day took 2008 Audi A4 with 64K miles in to our mechanic. …
