I feel that in certain situations when you press the accelerator down a bit to increase speed the gearbox kicked down too many gears for the level of acceleration you wanted, and takes too long to "realise" this resulting in you going along at higher revs than necessary for a good few seconds.

 

Am I along in feeling this? It happens in D and S modes.

The DQ400-e is 6 speed like a DQ250 but very different being fitted to a 1.4 TSI & a Hybrid motor. 

 

S will hold to a higher rpm than D.   

 I think what you describe is pretty much as they are.

Yes, I just feel they could be fine tuned a bit more.

It was fine tuned to get the low emission / WLTP results under testing.  Not necessarily to suit drivers. 

 

The issue about you having your own Mapping / engine management is voiding the warranty.   OK if your car but not if leased.

Yeah I'm not after my own mapping just improvements from Skoda to drivability. Also interested to see if anyone else agrees with me.

FWIW I've previously commented about my experience with DSG (Mk7 Golf). Broadly speaking it often seemed confused about which gear it needed to be in. Hilly country exacerbated the situation somewhat, the box would hunt up and down to the point of annoyance to trying to work itself out. It's over-revving in too low a gear was common. There are odd occasions when my 8sp TC trans in the Octavia does a similar thing, but rarely. Overall I find the 8sp a smoother gearbox.

@SouthernComfort  Which engine did that have, and which gearbox a 6 or 7 Speed Wet Clutch or 7 speed Dry Clutch? 

 

Hilly Country, short sharp bursts of acceleration, climbing etc is just exactly what S can be for, as explained in owners manuals.

It's not too much if you anticipate what's ahead or you know the route well, you can preselect the gears ahead of the box.

What?

Same engine as my Octavia, 1.4TSI. The Golf had a 7sp dry clutch, AFAIK the wet clutch only went into the higher torque models. The wet clutch was reputed to be a smoother unit, somewhat academic though. I am aware of the attributes of S, I alternated between D & S frequently. Frankly it made little if any difference to the situation we're talking about here.

DQ200 so 7 speed dry and a very low 1st gear really for starting off and stopping so something like below 6mph.  Not often selected when driving then.

Very different with various engines used with, no more than 250 Nm and from 192 ps in a Polo GTI 1.8 TSI down to 1.0 TSI,s and maybe 75 ps. 

 

A DQ200 could be equally as smooth as a Wet Clutch DSG.   The software / management was not the same from 75 ps to 180 with Skoda or 192 with VW.

Correct. 1st gear never selected when driving.

This is the case with the 6 speed in the Octavia too.

There are certain roads where I can beat the box at its own game, I select a gear that it wouldn't normally do, the B3224 Bishop's Lydeard to Raleghs Cross, the A39 Porlock to Lynmouth another, plus quite a few of the minor roads in West Somerset which I know.

I have the very same engine and transmission on Formentor PHEV, and never had the feeling that the car goes into higher revs than what I was asking via the accelerator. It happened a few times that it went to higher revs than I was expecting, but it was exclusively my fault: I was in S and I was downshifting (manually); once I resumed the acceleration, I wasn't paying attention that the car stays in M. However, you can easily avoid the high revs using the paddle shifter - I do that sometimes.

I only feel that for the "crawling" setting - I find it to be quite jerky sometimes, depending on traffic. When you're stuck in crowded traffic at very low pace, foot not even on the accelerator and the car barely moving, sometimes there's some "clunk-clunk" noise coming from the transmission (or the e-motor) that you can also feel in the car-body. I think that's caused by the car quickly oscillating between regen and traction - as it's unsure what to do at that slow moving pace. That could be surely optimized; I sometimes "force" the gearbox into M1 to avoid that behavior...

I never had an issue described by mccririck.

Though over time my car developed another thing. When standing uphill, even a tiny bit, car tries to start moving before brakes release and that causes quite sharp and very annoying punch. Sometimes even feels like someone hit me from behind. Dunno why it appeared over time and if that's gearbox problem or brakes.

Ok, that's a bit different to what I'm talking about.

As previous posts have mentioned, Skoda tune for the lowest emissions rating not for drivability.

 

Drivability has never been the main concern of car manufacturers, 35 years ago when I worked at an automotive consultancy and engine management was relatively new client car manufacturers didn't want drivability just low fuel consumption - the only difference now is they want low emissions.

But it should in theory learn this.

It is quite handy to be able to tap the upshift paddle if it changes down too much. I need to get in the habit of doing that.
