I'm sorry if this is an issue that has been addressed before. I've had my car for about 4 months now and have about 2600 miles on it. I have a 2.0T automatic and I do most of my driving with the paddle shifter. What I've been noticing lately is that when I get up to the 5th gear, the turbo kinda "dies." What I mean is when I go from the 4th gear to the 5th gear and accelerate, I can hear the turbo kicking in for about 1.5, 2 secs, then suddenly it "dies" and the rpm drops (ranging somewhere between 200 ~ 400 rpm). It happens mostly when I'm going somewhere between 40 mph and 50 mph, and on the 5th gear. As far as I remember this wasn't an issue.

I tried searching it on google, but couldn't find it, and it's my first car so I still am not familiar with all the possible mechanical issues. I plan on taking it to the dealer hopefully this weekend, but I just wanted to get an idea whether it's been an issue with other people, in which case I guess it empowers me to yell at the dealer, or it's just something I'm not doing correctly, or if it's something completely different. And once again, if this was a noobish question, I'm sorry.

Thank You

hmm sounds like something i'd get checked out for sure. I have a 5 A/T and havent had that problem at all with mine so far and i have a little over 3k miles on mine. Pulls all the way through for me. Wouldnt hurt to complain to the dealer anyways lol Good Luck and i hope you find your answer!

I actually have the same exact problem, except when I have it in auto mode and not sport mode. I'll be accelerating and once I get between 40 ~ 50 mph it almost seems as if it shifts to 5th gear too quickly and dies. It fixes itself once I take my foot completely off of the gas and then re-accelerate and it kicks back into the proper RPM position. This has been happening for a while now, SO glad I'm now not the only one with this problem!


Side-note, do you have any sort of re-flash?


EDIT* When I say "dies" I mean it gets stuck between 200 ~ 400 RPM

It's not that it really "dies" per-say, but it's more like something (whether it be the turbo or some other part) just bogs down until I re-accelerate

@zZz525 No my car's in the stock form. my car's been like that, and I thought it was just a minor issue that I can "deal with." But lately, even if I take my foot off and try to re-accelerate, it only accelerates for one or two secs then the turbo "dies" and the car ends up accelerating w/o the turbo boost. Yeah as soon as the road's clear of all the snow, I will take it in to the dealer and see what's up and will update you on it.

Yeah I have a reflash and it does it ... so it must not be that then thank God. I actually have a service coming up next weekend. I'll mention it to them and see what they say. I'll keep you posted as well.

No issues here with that.

What RPMs do you see when its shifts?
Stock turbo has a weak high end, for a turbo.

Cruising below 2K rpm, it has no torque because the manifold is seeing vacuum.

Mine shows the needle basically right at 2000 RPMs, and gets stuck there regardless if I push the pedal down farther to the floor. It only gets past 2000 that if I take my foot completely off the pedal and re-apply pressure.

If RPMs ever drop in an AUTO while your foots on the floor, get to the dealer ASAP!

There are a few reasons your rate of acceleration might slow but nothing should cause a drop in RPM other then a slipping clutch and that ain't likely the issue for you :rofl:

How is your engine still running at 200-400 RPM? I would expect it to stall out...

That said, if you're going 40-50 in fifth you're for sure out of boost.

Nah, my car does this in fifth... If you slam the pedal down in fifth at like 3,000 RPM the tach will spike up a bit, 500 RPM or so, and then drop back down. I'm pretty sure this has more to do with the torque converter being engaged than the transmission slipping. I have a video of it. My girlfriends automatic, completely different car, has this behavior as well.

I have an appointment with the dealership Saturday morning, so I'll let everyone know what they say since mine does this also

And mine does exactly this ^^

The more I accelerate the more my RPMs drop :ugh:

Sorry I've been kinda out of it - school starting, mid-west getting owned by the so-called "Apocalypse storm" or whatever the nonsense people are calling it by. I haven't had a chance to go to the dealer. But I tried some empty road "tests."
Basically, when I move up from the 4th gear to the 5th gear and the car is cruising at about 45 mph, if I step on the pedal hard enough to maintain the rpm above 3000 the boost stays. But if the rpm is below 3000, even at around 2700, I see this sudden drop (as I mentioned rpm drop of 300~500 rpm). And I also run into the same trouble as zZz525 where I see a power-drop even if I step on my pedal hard enough, and it isn't until I take my foot off and have to step on it again. Additional problem I'm having is that even if I step on my pedal again, if I don't reach a cruising speed of 60 mph or rpm above 3000, I see the power drop again. I initially thought maybe this is some kind of negative boost feedback to make sure the turbo doesn't get overworked. I've minimized the use of the car in case there's any damage being done due to this issue.
zZz525 - please let us know what ur dealer says about this. I'll also try and make an appointment with my dealer as soon as the roads are clear.
