Lack of Power and Responsiveness HELP

[mikeman101433]

Hey Guys need some help.

I have a 2015 Audi S4 stage 2 APR Auto DSG Tiptronic, I was at a light today and floored it and between either gear 1 and 2 or 2 and 3 the car lost power but after about 3 seconds it came back and kept driving. Heard a buzzing noise for a second but that went away. Now my car is significantly slower and not as responsive as it used to be. Very nervous that something really got messed up. No check engine light or any abnormal noises anymore just lack of power and response.

Please advise I know nothing about cars

Thanks Mike

Same thing happened to me yesterday, I floored it and it almost felt like the clutch wasn’t grabbing. 3 seconds or so later it started moving again.
DSG as well....

Sounds like a vacuum leak especially since you mention the buzzing sound

Best is to scan the scan and see if any codes come up.

I have the same thing happen to me last year. My power steering was acting up a week after the problem. Turned out to be my crank pulley after searching the forums.
