hi gays

i have audi TT 2000 with 90K miles some times when i go fast on the first level transmission the engine makes a noise like something hitting it and a light appears in the middle of the RPM counter inside the car this thing doesn't appear if i go slower, and does not appear on other transmission level even if i go very fast please gays I am really worry about the car. Do I have to put batter motor oil like synthetic or I must put something to protect it, please gays help me.

 

easy fix!! all you gotta do is go 90+mph and drive off a cliff.
