yup ive done that once or twice, went too quickly into reverse...grind -_- not a nice sound

Anyone with GTI's ever randomly put their foot down (WOT) and get no power?

Isn't due to the weather as it has happened in all conditions but those 3 times turning off the car didn't solve it. It'll just have no power then all of a sudden next time I try WOT, it would be back to normal and then next time nothing again?

Were you moving are at standstill? May have been traction control?

not sure if this applies to GTI's as much as their turbo is smaller, but hot weather and turbo's dont mix. i know on very hot days, my TT supra can be slower than a corolla

Actually I think KAM has got it. I think the term is called heat soak (I am all for been corrected) but I do notice that when it is a hot day (over 30) and I am driving long enough to warm everything up and then stop, turn the engine off and then come back and turn it on within 5mins - 10mins and drive there is no boost what so ever for about 30 seconds until the water pump starts cooling down the turbo. You can have you foot as far down as you want but it is exactly like a naturally aspirated 1.2L engine pulling a 1.2T car. The result a very VERY slow take off.

The problem is that in hot weather the only thing cooling down the engine is the cooling circuit, not the ambient air so when you stop the engine and thus the flow of cooling, the temperature of that turbo will go from the water temp of 90 upwards to exahust tempretures (450 degrees mabey) before it starts to cool off naturally.

This can result in massive boost losses as the air/fuel mixture has to be massively thinned out to prevent pinging. This could also be the case in peek hour traffic as there is no air flow, though the engines cooling circuit is still one so it should prevent heat soak for the most part.

After you drive with some airflow for 30 seconds or so it picks up boost again and seems to be fine until you stop the car.

I drove my GTI on the 40 day a couple of days ago up and down Arthur's seat, no heat soak issues here. Could be due to the intercooler but seeing as fast lane has had it in different conditions, I'd wager it's something else at fault....

[fastlane]

Definitely not heat soak as both times this has happened during 20 and 35 degree days with TC off once noticed. Good reasoning though thanks guys! Jake, exactly like you explained though, it feels like no boost!

Car is getting its 15k service soon (Burwin Commercial) but as it's a Saturday probably won't get to find much. Doubt it logged a code either.

On another note, I get clunking with my DSG with on/off throttle from 1 to 3 gears. Sign of problems ahead?

Car is awesome though, love it and I guess I always expected to have these issues, especially with the DSG

We shouldn't have to expect issues in brand new cars. It's not like the DSG was only just invented!!!!!

I experienced this for the first time last Thursday when it was hot. Drove from Melb CBD to Melton. Exited freeway, approached the roundabout taking foot of the gas, left hand turn and give it the gas again and then nothing for a good 3-4 seconds....then it kicked back in.

Yes. A few times, and only one on a warm day, but not as severe as you with regards to it coming back.
In fact, the times I've had it happen to me I've almost been collected by other cars.

The first 2 times it was sitting still behind a car at lights, and attempting to move into a lane that was moving, so I would have had the steering wheel turned when I attempted to get power. Put my foot down for a burst of speed - not all the way - moved maybe a few inches, then lost power - like I stalled. Took foot of power, put back on, and all was ok.
No Traction contol light, no wheel spin, just no power.

Next time, was turning left out of a driveway of a servo, and needed to beat some oncoming cars - and again, moved a little, but had no power.

Happened again yesterday, but can't be certain if I had any turn on the steering. I might have had a little, but not as much as the first few times. But luckily no oncoming cars this time.

Every time it's just a "one off" that day. Can drive for hours after with no recurring
issues.

Well you all seem to be explaining very similar situations as to what I suffer... Now what the problem is?!

I've had this - usually half way into or on a bend and no throttle response. 3-4 fearful seconds, and then too much boost. Not a nice feeling powerless trying to merge into traffic

[kam]

not sure the likelehood of this happening on brand new unmodified cars, but a boost leak could be another issue, but from what you guys are describing, you get no power at all

even with heat soak/boost leak, the car will move, it will just be very slow

would you describe it as a hesitation ? if so, then i would say gearbox. gearbox for sure.

the supra did it once, scared the **** out of me, as i was trying to quickly pull out of a side street as there was traffic coming. normally this would have not been an issue, but for some reason the gearbox hesitated, like it didnt know which gear to go in, so it just sat there for about a whole second, which doesnt sound like much, but when you have a large 4wd coming at you at 70kph...

it could also be your traction control system, sensing some slip and cutting a lot of power

just throwing some idea's from personal experience

[ill0gitech]

I've had a lot of conversations about this, with other polo owners and people in general car service (not VW as yet though if it happens again I likely will)
With regards to hesitation, for me, I've always been in first. I've had some initial movement, so the car must have been in a gear (not roll - I assure you). The car stays in D1 or S1 and doesn't look like anything described around false neutrals. Despite my recollections to people on the Sydney trip the other day, I don't notice a thud or anything of the gear coming into place as has been described in some DSG hesitation complaints.

As for traction control, this was the first thing suggested to me, and I've had a wide variety of descriptions on how this should work.
Typically when I dump the accelerator too hard at lights, or on a rough surface I notice two things. 1 - wheels stopping and starting to find traction. 2. the traction control light flash.
In all but one of the times I've had this happen, it's been a well tarred road with good grip and the acceleration hasn't been massive. In the most recent time, there was some loose stones (oval car park) but I wasn't accelerating hard at all.
Short of disabling traction control every time I get in the car, I'd like to think it's not the traction control.

Always rolling. Usually 1st or 2nd gear. Always immediately after a power off (no acceleration). Throttle pressed 1-2cm ... No revs, no increased momentum. Engine rpm stays below 1k rpm, and car coasts.

Definitely not traction control. Don't know if its the dsg as the engine itself just seems disconnected from lite throttle inputs. Then whoomf your off in an un dignified manner as the engine comes back from the dead.
