2000 Automatic Audi A4 drives fine for about 10 minutes then struggles to pick up speed
eg. after coming to a stop and going again, car will have a hard time getting up to 60 kph. fixes after i turn the car off/on again but then process repeats after 10-15 minutes.
I leave home to travel for work, 5 minutes in im on the motorway and get up to 120kph and the car then stops picking up power and takes a very long time to go to 140. Other days it gets to 140 effortlessly. Also notice it when i come to a stop at a junction for example, it will take about 10-15 seconds to reach 60kph from a stop.
No idea whats wrong. any ideas? if you need more info let me know.
