So sorry for posting so many times about this problem with my car. I swear ill get it fixed someday! haha
But listen to this, my car has been acting funny. CEL came on and threw some lean codes, audi told me problem
and i fixed. since then car runs really weird. replaced the fuel filter, spark plugs, coils, and this is what happens now.
Like an idiot i didnt clear the CEL codes and now sometimes the turbo wont spin with throttle.
Ill get in car, start car and i can give it full gas, and the engine does not cut out, but the turbo isnt spinning.
Sometimes i get in my car, and the turbo does spin fine but the engine cuts out when i give more than 10% gas.
Anyone ever heard of this?

 

get it scanned for codes again and post them here.
