Hi, i am new to this forum but decided to post my problem since the dealer cannot fix it. since a few months, i randomly get loss of power, mostly in 3rd, 4th and 5th gear. 1st and 2sd seem to be doing better. It happens 80% of the time, it is like the turbo takes a while to start spinning when i press the gaz and the car doesn't pull very hard. If I realease the gaz and then press it again, sometimes, the power comes back. Usually, even a slight pressure on the gaz after 2200 RPM used to make the turbo spin right away and the car pulled hard. Also, sometimes, i would feel the car start pulling normally when pressing the gaz but it would suddenly die (very obvious when the noise reflects from a walll) . Also, when pressing the gaz lightly, it seems like the power come by stages, not smoothly. I feel it mostly in 1st, 2sd and 3rd gear. I had the Mass air Flow changed twice already (even though if was broken, it didn't change anything) as well as the DV (improved things for about 2 weeks). My car is stock and over maintenaid (oil, steering, wheels, brakes and so on changed and checked every 5 kilos) and the dealer doesn't read any error code and tells me that there is no problem (of course, this morron doesn't drive the car 1 hour a day, everyday !!!). Montreal, Canada, is very poor in real german car specialists and I do not know what to do. I paid a fair amount of money and even if the car still runs ok for everyday use, i'd like it to run perfect. I am fed-up to see the Honda Civic and other match boxes at half the price of my car pass me all the time. Any help would be greatly appreciated. Thanks in advance. Aurelien
