Dear Gentlemen,

Skoda Superb 2018 2.0t 280 hp with DQ250, current mileage ~90k km. From the day one I owned the car, I'm not convinced that the gearbox operates properly.
Particularly the 5-4-3-2 downshifts in D mode are unsmooth while working brakes are applied. This happens only when brakes are applied. If I let the car freeroll and downshift itself without brakes, all gear transitions are ok. The "unsmoothness" could be described as jolts or bumps accompanied with aggressive engine braking effect.
If I select the Eco mode (with coasting disabled), then everything runs smooth as butter. It's very noticeable that downshifts then happen later, at almost 1k rpm, and without extreme engine braking.

I'm really confused because, as far as I'm aware, D and Eco modes use the same maps...

Any ideas, can it be solved software wise?

Gearbox info:
HW: 02E92777AS
SW: 0D9300018C v. 5201

i have a late model 2015 passat 3.6 dsg in one car and earlier 3.6 dsg in another and the later one has like a hill decent control when brake pressure and angle of attack are just right so i would say its normal behavior for an mqb dsg if my late model fxx dsg does it. i only recognize it because my 7p touareg has the feature also.

Can the efficiency mode downshift behaviour be applied to D mode? Tallinn is few hours drive for me.

Please dial down the arrogance. Dealer already did experiments costing me quite some cans of beer.

Weirdest thing is that it tends to rectify itself to bearable level after "drive it like you stole it" session.
My first thought was that it is a mechanical fault, which reacts to gearbox oil temperature, almost ordered new mech unit, but common sense took over me and before that I tested two other random Superbs with same engine + gearbox setup, different mileages and manufacturing years. Both behaved very similar. So the chances that three random cars have same mechanical fault are not so high, same s*** software - way more higher.
Neither two dealerships or two dedicated gearbox service garages could confirm at least somewhat sure mechanical fault due to nature of complaint. Oil was drained, no excessive impurities, mech unit cover was removed - no metallic debris on solenoid magnets.
Only one other thing that might slightly point to an actual mech unit issue is an occasional clumsy 1->2 shift at low throttle. No bang, slap or even jolt, but I can feel it.
Maybe it's worth to do some more experiments with existing mech unit (hydraulic part cleaning + solenoid replacement) during the next scheduled service with a hope that it will at least not make things worse.

After owning three dsg cars I think that my next one will be again with ZF or Aisin conventional automatic gearbox.

The gearbox has a dynamic driver profile from 0-100% and interpolates between two maps (one being 0% other 100%) based on the percentage.

So the formula is map1result*(driverprofile) + map2result*(1.00-driverprofile).
This is for shift RPM.

Anyway, all this stuff you have to do yourself, or just give up on it, this is the real scenario.
If you want to do it yourself as hobby there's easily enough ways to do it quite cheap these days. PCMFlash, the damos is possible to get and also the funktionsrahmen document.
The financial investment is probably below 1000 EUR, it's the time that matters.
