DSG hesitating on downshift

Lou i think the problem for you is (which isn't a problem as such) that you are going from 4th to 2nd which is controlled by the same clutch so it has to disengage 4th and select second which is probably the hesitation you are feeling.

....That's what I was alluding to. Same difference - Lou is 'forcing' the shift. I still say it's not a great way to drive IMO whether DSG or manual or on any vehicle.
vRS Carl:
I was refering to the "being in 4th and having 3rd and 5th simultaneously ready" bit :P

Have you had the dsg box serviced yet?
You have vcds? perhaps its worth doing basic settings of the dsg if you do.Although ive never tried it.Perhaps maybe an error with the downshift paddle? although vcds will show an error if there is.
Or ask your dealer whilst in to investigate whilst your factory warrantys still valid?

Steve, car is 22/01/08 on a 57. 22300miles. No DSG service yet. Factory warranty for a few more days! MOT on wednesday so I'll have the dealer on it. So they can have a look.

Robin, yes I'm 'boxing' the shift as Police instructors taught me. I suspect that if it were an issue of technique, this would have shown itself before now. Unless my technique is gradually knackering something? Plus engine revs are very low, and peak below 3k (i've been watching & testing). My thoughts are toward the second clutch having to 'catch up' perhaps? In any case, Robin, I'll definately try spacing the shift more widely as you suggest.
It's worth clarifying the double click; it's not like a pc mouse; I'm shifting both ratios over about a second or slightly more. I have on several occasions noticed the same hesitation in D. Usually on the approach to a roundabout, the box is downshifting, and as I identify my traffic gap & apply throttle (while still rolling) the same can happen.
My issue revolves around the question of is this just a trait due to my driving style, or the box, or an impending fault?
Keep it coming please. I'm off to give her a bloody good wash down, fluids & pressures, and hopefully poke about with VCDS
Really I'm asking you guys to keep brainstorming
Hedge:
I do the double click to change down, it's only the same as going from 4th to 2nd or 5th to 3rd in a manual, and my DSG box copes with it.
It isn't the sharpest tool in the box with other things I ask of it though. :fighting: :fighting:
As has been said get it into the dealers and at least logged as a fault that they are investigating before your warranty runs out.
vRS Carl:
As has been said Lou,
Do a VCDS reset. This will only reset everything to default and it will learn all the shift patterns again. It may cure it initially but if it comes back then it is a good indicator of something else being a problem. More than likely the mechantronics unit.
From what you describe in your last post it seems similar to how mine behaves. Mine is on a diseasel granted but the same sort of thing happens (although i don't have paddles) when im approaching roundabouts etc. I had mine serviced, the dealer said they can run a test to see if the Mech Unit is on the way out and after the test they said it appeared fine on mine.
If it was me i would take the car to a dealer, describe the problem and see what they say. Especially as you have a few days left on the Warranty they may just replace it anyway. :happy2:
