i'm at 1300 miles right now, so this is on a new car. i was making a right hand turn the other night and a car came flying around the bend towards me. i had to gun it, so i did. and for about 1 second, nothing happened. then, BAM, the car shot forward and took off. it literally felt like someone ran into the back of my car. what the hell happened? i would have gotten creamed if it didn't take off, but there was a definite lapse between when i hit the gas and when it actually engaged. haven't had any other problems and can't recreate it as of now.

 

This may or may not have anything to do with what happened in your car but, you ought to take a look at the post titled, "A3 Power Failure".
There are some serious power delivery failures occurring with some 2.0T motors. Conditions such as temperature and altitude may possibly be playing a role.

 

i've been following that thread, and it seems to be a different issue for me. it was a momentary lapse between when i hit the gas (from a stop) and when it engaged. and when it engaged, it engaged hard and nearly gave me whiplash. there wasn't any power loss other than that and it got to speed pretty quickly and drove normally from then on.

 

That does sound like it could possibly be an unrelated problem.

 

Turbo lag?

Most reviewers say that turbo lag is practically nonexistent in the 2.0T FSI, but there are some situations in which turbo lag is definitely noticeable. And of course it happens when you least expect it, e.g., your situation, or when you want to shoot out of a driveway into heavy traffic and it lags for just half a sec.

 

have this exact problem too rolly

i drive very aggressively and there are times where i wanan take off or need power but dont recieve it right away



FYI i had my DSG valve body and control recently replaced, my car is much better now, i have 8k miles on it and have only owned it since 6k miles.

 

I remember reading about an issue with the new Toyota Camrys (I think?) where they were equipped with an electronic throttle body and the car would "learn" your driving style. Well they started having an issue where the car would learn that the driver never mashes on the gas, and then when that driver did have to mash on it to avoid a wreck, the ECU would not open the throttle all the way, effectively overriding the driver's input.

The A3 is also equipped with an electronic throttle body and I was told by the salesman that it does "learn" your driving style so it can predict when and which way (up/down) to shift the DSG transmission. Since the original poster has only had the car 1300 miles and is likely still breaking it in, is it possible that something similar happened here? The idea of an electronically controlled throttle has always made me uneasy.

One other thought, I've noticed on my A3 that occasionally when I am driving in manual mode, the car hesitates when shifting from 1st to 2nd. It is only when I floor it from a standstill and it seems to only happen when I am turning (i.e. from a stoplight making a left turn). I imagine it is adjusting the revs before engaging 2nd, but I'm not sure. May be a similar issue to what rolly has.

 

happen to me the other day.
a big jerk boost its like the car is shifting agressively.
this is after the TCM is replaced.

 

BAMF - Definitely true about the "learning." I received my A3 back after service and the power curve was completely different than when I brought it in. Audi service said that the computer had probably been reset and "re-learned" the driving style based on the tech babying the car after the service - hence the slow power application. He suggested unplugging the battery for 5 min to reset it and it worked perfectly. After the reset - I could immediately feel the difference. By the end of the day, the power application was back. Not sure if this sheds any light on the orig problem posted. Hope it helps someone though!

 

DSG lag. thats what you experienced.

From my experience when I mash the throttle while in "D" the car would go/say something like this.

Car - "Hmm, master wants full WOT"
Me - "WTF, go already... I need you to go"
Car - "His foot hasn't moved yet, let me see when the last time he wanted full throttle in D... ahh yes, 300 miles ago"
Me - "Hello?"
Car - "I forgot how to open my throttle plate to full open, I think it goes somethink like this"
*Tires burnout*

I've expereinced anywhere from 1-3 seconds of lag when doing the said above. It is true that this car does learn your driving behavior but it can be dangerous at times. Whenever I needed instant power, I would usually shift it to S and then go full WOT. It was the only way I could ever get it to respond fast enough.
