dsg upshift delay

[sameatworld]

Hi, am a newb with 07 GTI 5door DSG. Very excited!

Have driven the car in manual mode all day today and have found that there is a delay in upshifting from when i flick the paddle. The dash display of gears changes up but there is this delay of 0.5 seconds or so before the gear is changed. Hence the car ends up being revved for that much longer. Just wondering if this is normal for DSG. I sorta expected much more instant, playstation like response, for upshifts anyway.

Thanks

Doesn't sound like something normal, unless its only occuring when TC is kicking in. Should feel that shifts are almost instantaneous.

Break the car in first. The DSG will adapt to your driving style over time and once everything is settled in nicely then you'll start getting the near-instant shifts that are DSG's strong point.

In manual mode there is no "learning" period. You should have instant shifts. If you are lifting on the upshift you may find that it lags. Not a half second though... You should take it back to the dealer and have them look at it. Good luck.

this occurs when the car is first started up because the transmission isnt warmed up. youll also find launch control disabled the first few minutes because in order to use launch control, the trans needs to be warmed up. after a couple of minutes of driving, the shifts should be nearly instantaneous. if its still shifting slow, then just take it in to vw and see what they say

This happens to me every once in a while. It's no big deal unless it becomes more consistent and/or troublesome. Make sure you're always accelerating when you upshift too as that will shorten the shift response time.

This happens to me as well depending on when I click to upshift. Other times it's instant.

Gotta give the tranny a few minutes to warm up a little. When I first start driving in the morning the shifts are a little slower, but after about 5-7 minutes its "whapwhapwhap through the gearbox" like the brochure says :thumbup:

Will be taking the car back to the dealership today afternoon for electronic diagnosis. Strange thing is that i have not really noticed this delay with other DSG cars that i test drove which included another gti, gt and tdi. Maybe i wasn't paying that much attention...

Downshift is quicker than i expected (as the engine needs to blip and then gear engages) but delay in upshifting is throwing off the driving. Especially when going around the corner coz it will "hold" the gear even though it's been upshifted. Makes for much rougher driving with unintentional revving.

Will see if the diagnostic finds anything. Probably not by the tone of the service dude...

it also can happen when you don't give it gas when you shift.

I've noticed you have to be on gas (in my test drives as I don't own one) or it is slower.

I'm wondering if the car uses the throttle to determine whether to be ready for an upshift or downshift? Since the "next" gear is already engaged, would the car interpret on-gas as having the next highest gear engaged while the off-gas means the lower gear is engaged?

ie. you're accelerating in 2nd. because the car knows you're accelerating, it has 3rd ready to go. shift is instantaneous to 3rd. Or, if you're in 3rd, but off the gas or braking, the tranny has 2nd pre-engaged, and the downshift is lightning fast?

I found that almost every time if I let off the throttle, then hit the upshift, it took longer. But what do I know. Don't own one. Just noticed on my (way too many) test drives :)

[sameatworld]

just been to the dealership. Had a diagnostic check and apparently everything is ok according to the computer... the guy said that he reset the transmission programme. But it still seems to have that delay tho.

what i don't get is, if the computer is trying to guess the next gear, why is there a delay between the 1st and 2nd gear? i mean it's not like it's got another choice! There seems to be the most delay in upshifting from 1st to 2nd.

On motorways it seems to change ok. well it's not that noticeable because the revs are not that high.

Anyway, was told to drive a bit more for another week and if there still seems to be problem then to book it in for a more thorough check.

I dont mind if this really is how DSG shifts. What i do mind is if my car is the only DSG which has this delay! >.<

You shouldn't be up- or down- shifting in the middle of a corner anyway...upsets the car's balance :biggrin:

[Si Killer]

yeah if you pulled something like that in a rwd car you'd probably screw the car up pretty bad. thats what happened to my buddy's 325i

[UMassJ77]

when shifting gears keep accelerating(don't lift your foot off the gas)...if you lift off the gas you will feel a delay..the DSG computing whether u want to slow down or speed up.

It takes time to adjust to the DSG, it's not your run of the mill auto tranny. time will help.

Interesting comments regarding the upshift delays and that it could be due to lack of enough throttle when the padle is actuated.
My problem is on downshifts while going uphill and with just enough throttle to maintain speed. Hit the paddle to get the lower gear for a pass and I get NO throttle for 1/2 or more second and then it grabs the gear and off I go. But, no throttle means I actually feel deceleration before I get to go. I am not sure how to avoid this with my driving style and sure do not like this. A MT will never give me that kind of 'service'.
I'll try to modify but I want the car to do my bidding and not have to cater to its idiosyncrocies.

Toothscraper, how many miles have you done on your car? That sounds unusual to me... whether I downshift or upshift, just maintaining speed, the shift happens immediately with no loss of power, and certainly no deceleration.

Push down on the throttle a bit more before you downshift. The 1/2 second delay will be all but eliminated. The tranny determines what gear to pre-select based on throttle position. If you were travelling uphill maintaining speed, the next gear up was probably pre-selected. But then when you paddle shifted a lower gear the throttle position is essentially locked in place for 1/2 a second while the tranny downshifts.

Cliff notes: press throttle first, then downshift.

[RobbDizzle]

Yeah I notice that it hesitates at part throttle too, but shifts really quickly at moderate to WOT. I have a steep hill I go up to go to work everyday that usually requires a downshift. I either give it a touch more gas or just downshift before I hit the hill.

I'm about to go DSG can anyone explain a little about how you work the launch control?

1) Left foot on brake
2) selector in S (or tiptronic mode, but S works better)
3) ASR off
4) right foot on gas
5) rev to 2400-2500 rpm
6) lift left foot off brake, ful throttle
7) hang on

[Jethro41]

Thank you Robbdizzle...I'll keep step 7 in mind

[Toothscraper]

Cmdrfire & Slickvic,
Thanks for the input.
I will try the throttle technique before the downshift and see if this will solve. The comments suggests it is an expected response.
Getting the most our of a vehicle can take some adjustment. I am up to 12,000 miles and finished off the OEM tires after 9,800. I drive hard, tailgate on the mountain roads that I drive 40 miles each day and will tweak to see if I can deal with this. Does not happen on all downshifts and making controlled tests is a bit hard.

Stay tuned for my next postintg in a day or two about a weird noise/thump on downhill turns.

DSG should shift instantly unless you are lifting off the gas and then shifting then you will definately get a lag.
