After, i serach in the engine for some failure, and i've found the IAT and barometric sensor unplugged, i have connect them and i've cleaned the throttle body (also the throttle position sensor).
Now the car run pretty good, the dead spot are almost disappeared (some random between 1500/2000 g/min), maybe not enough power in WOT in high revs… and the vag say this first:
