....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.


^^^^

Why is that a bad way to drive a Manual?

In a manual you stick the clutch in, and select 2nd from 4th, and ready for a junction, bend or get instant acceleration capability for an overtake manouver, as long as you don't over-rev the engine what is the problem in a manual?

 :popcornsoda:

....Sure, you can do it but IMO it omits using the engine braking. As you rightly point out, it's important not to over-rev the engine and that's easier to do if you're in the habit of double-clicking. I think it's a lazy way to drive too. Just the way I've been taught.

If I was being lazy I would just let the box downshift itself.

By double clicking and dropping 2 gears I have used more engine braking.  :confused:

I certainly don't see a problem with dropping more than one gear. As long as you get the revs to match for a smooth change then it's fine.

I think the problem would be if you just went from 4th to 2nd and sidestepped the clutch.  :laugh:

Robin, as you have such fast road/track experience, have you noticed anything similar if you, for example, had to hurry a shift into a bend?

I wonder if it's worth polling the DSGers amongst us regards hesitation (in auto mode) as I described.


....I don't have a lot of track experience - Some, but not as much as many here. But I do have 90k miles of DSG experience in my GTI.

When I first had my DSG way back in 2005, I didn't feel comfortable with the small plastic oem paddleshifters and drove for several thousand miles in D but always used S for overtakes and a series of spirited bends. I've never liked the feel of nudging the floor stick and have only used that method less times than I can count on one hand. In reaching for the floor stick I find it natural to expect a gate.

So, at around 6k miles my Mechatronics module hiccup'd and VW replaced it under warranty although there was only one incidence and the car drove normally straight afterwards. I have experienced, like many others here, clunky shifts but they have invariably been down to cold temperature. I now always let my engine warm up so that the revs drop before I engage any gear.

From time to time I have experienced hesitancy but only in D or S and it has always seemed to be just a delay on gear selection probably down to the DSG brain momentarily being unsure about what my right foot was asking for. It has always cleared up after a few miles of 'retraining' - The DSG 'learns' your driving style.

Since Revo remapped my DSG box, none of these problems have occurred except for the cold temperature IF I don't settle the engine first.

I hope this helps in some way  :happy2:

That's odd :confused:

Mine hesitates in P & N as well :evilgrin:

x2.  Experience more engine braking by dropping 2 gears.  Perhaps that is just me and you Ian. Guess I am lazy!  But at least I use my left leg!

Right gear right time, I don't want to spend 100 yards changing 2 gears in my manual box, where I can slap it down 2 and use the engine braking available in one constant flow, and thereby not unsettling the car.

Just the way i was taught to drive, on several courses I have been on.  ETTO.

Yup no probs with box shifting in a manual imo...if it gets u into the right gear for the bit of road ahead. i do it now and again. 

no delay whatsoever either  :wink:

....That's right - ETTO and it's the way I've been taught (rightly or wrongly) and it's the way I'm most comfortable with.  :smiley:

Just make sure you don't go straight from 3rd to 1st when DSG  :grin:. 1st is a very short gear on the Mk5 GTI.

I think that there's more liklihood of getting it wrong on DSG than manual. Yes, the DSG will do it and I hear what some of you guys are saying but I think that DSG is happier going through the gears rather than 'boxing'.

.
Actually thinking about it further: I don't agree with whoever said that the car is more stable when boxing - It'll depend very much on how you want to use the throttle at the time, by putting lots of power suddenly into a much lower gear you may risk unsettling the car. Anyway, we [for Carl's benefit] can talk about this all night and achieve nothing.

It will only go into 1st if you are going slow enough, well at least with OEM software that is.  :smiley:

Also you can't 'box' per se with a DSG box as you can't miss gears, you can only simulate it.  :wink:
