2021 Polo GT 1.0 TSI upshifts only after 3000 RPM

Hello everyone,

I precocious purchased a utilized 2021 Polo GT TSI 1.0 which clocked conscionable implicit 10k Kms. The car was beauteous overmuch unused and person been sitting idle for mates months. The erstwhile proprietor claims that the artillery was precocious changed from VW work centre arsenic well.

Now to the occupation I person been facing with this car. The upshifts hap lone astatine 3000-3100 RPM driving it with a airy ft and D mode. Shifting from D1 to D2 hap astatine astir 2600-2800 RPM but each the remaining cogwheel shifts hap precisely astatine 3000-3100 RPM. I had it taken to VW work centre for a afloat inspection and service. I mentioned this to them and they recommended resetting the transmission module which they did and did not lick the issue. I went for a transmission fluid alteration aft that arsenic well. New transmission lipid worthy astir 16k was enactment into it and the shifting inactive happens supra 3K RPMs.

The weird happening is that, erstwhile the car goes successful a flimsy downhill(descending a span for example), the shifts hap normally. That is, upshifts hap astatine 2400-2600 RPM. But driving connected a level aboveground again causes it to displacement astatine higher RPM. The downshifts are perfectly good and hap astatine astir 1500 RPMs.

The shifts are food creaseless without immoderate issues and I person enactment an further 3000 Kms into the car. The adjacent enactment VW work centre recommended maine was to rebuild the transmission which I said No to. I besides had the car taken to a 3rd enactment premium car work centre and the feline said that the shifts are wholly ok. There are nary mistake codes whatsoever.

I besides came crossed a station by a subordinate present for a reappraisal of Sunset reddish polo GT TSI which had the aforesaid contented erstwhile it was caller but was solved aft the Run-In Period.

I americium attaching 2 videos present which demonstrates the issue. One is connected level aboveground which is 95% of the clip and the different 1 is going down a bridge(where it shifts normally).

Any suggestions oregon thoughts would beryllium highly appreciated. Thank you.
