Greetings fellow vw/audi lovers,

I purchased a genuine vcds a couple of weeks ago and today i decided to play with things i dont quite understand yet(i intend to). As the title says, i reseted some values and now my car is a bit sluggish, delayed throttle response and very rough and loud when accelerating. MFD is also reporting huge fuel consumption, over 7l/100km. Can someone, please, explain whats the best thing to do now? And no, theres no engine lights.

Many thanks
