You probably accidentally disabled seat memory. This is usually done by moving the seat to its extreme and holding the button down for a few seconds. You have to turn ignition on (engine does not have to be running), exit the car and move your seat to its extremes once more - both base and backrest all the way back and then all the way forward, then you should hear a "bong" that lets you know it's working again. Keep in mind that after you move the seat to the front or back, it actually stops a few centimetres before the end - you should then release the button and press it again to make it move all the way, otherwise it doesn't count. I've done this procedure a few times. You should also know that it's pretty easy to screw up the process so you might have to try a few times. If possible, I'd recommend automatic relearning using a diagnostic module (OBDeleven, for example) - same process but the car does it for you. NB! When you move your seat all the way forward, double-check that you headrest is removed or at the lowest height. I broke my sun visor mirror with it while using automatic relearning as the seat went all the way up and forward and pushed the headrest into the visor before I managed to stop it.

Success for me with a revised clutch pack from June 2016. Still working fine.

Yes, there are different trunk buttons - smaller one was used when there was no factory camera option available at all.

As I "retrofitted" (coded in) TPMS myself, I remember that the glovebox unit had its own coding to allow resetting it. First there is coding to enable TPMS itself, including the dashboard TPMS light, and another one to enable it on the radio. Yours is probably incorrectly coded. Find someone with VCDS or OBDeleven and let them check.

You most probably have an issue with the engine itself that you're not going to fix by switching oil brand from something that was officially used by Škoda (at least in some countries). Officially stated maximum "normal" (actually in extreme driving conditions) consumption is 0.5 l / 1000 km and you're already exceeding it. I had half of my engine taken apart and rebuilt (although it was a different engine) under warranty when I had similar consumption (fixed after changing to updated piston rings and pistons).

Maybe you already tried it but... The procedure is as follows: first "Set", then press the number button. Not together, not just "Set".

This means that the site uses regular HTTP protocol instead of HTTPS. Not related to trustworthiness of the page.

You'd need to program the battery (at least change one digit in the saved serial number even if it is otherwise exactly the same), anyone with OBDEleven or VCDS can do it.

The problem seems to be resolved now. Almost 4000 km driven and oil level still at max.

It will probably be sold but... why on earth would I just accept putting oil in it if I have warranty to sort it out?

0.6l per 1000 km is excessive according to Škoda. The manual officially states 0.5l / 1000 km to be the maximum "normal" oil consumption depending on certain driving conditions or engine load. So not a case of "not that excessive". I live in Estonia, we don't have hills to coast down from, and I use the gears the DSG chooses. As I understand, the problem may come from piston rings but for similar cases, the pistons are usually also affected and worn. I forgot to mention that the piston rings would also be replaced but it would have been a logical assumption that the rings would be replaced with the pistons anyway.

This topic is here to inform other people who might be dealing with similar issues. When I tried to find any topics about other people's 1.2 TSI 77kW engines of the same version having high oil consumption, I could only find something here and there but not a longer story with more information in one place about the additional possible symptoms or what actions are taken by the service. My 2014 Octavia's 1.2 TSI engine has been using some oil since the beginning. As it needed only one top-up just a few thousand km before annual service, I wasn't very concerned as I understand that this is actually normal with these engines. I think was some time after 45,000 km service when the engine randomly started stuttering and shaking, lost power, and "check engine" lit up. Interestingly, a restart solved it but I still reported it. The dealer took it in, investigated and found that the spark plugs looked "strange". I was asked about increased oil consumption but as I hadn't noticed anything different back then, I reported "one top-up not long before service". As they were uncertain about the cause and no oil issues were reported by me, just the spark plugs were replaced under warranty. After 45,000 km service, the next top-up was at about 51,000 km. At 56,000 another top-up was needed. I remembered the question about oil consumption so I reported it. Nothing was found. During 60,000-72,000 km, the car used 4 litres of oil. During that period, I reported the continuing and increasing oil usage again. A minor oil leak was found and the valve cover gasket was replaced. Also, two more issues arised - random (minor) stuttering at idle and start/stop system randomly failed to start the car normally (started up, then died at the same moment, started up again fine, then - but not always - reported start/stop system error until restart). When scanning with OBDEleven, I saw that "cylinder misfire detected" was logged with a note "intermittent" on all 4 cylinders and misfire counter could also be seen increasing pretty frequently when looking at live data. The car was taken in again and this time it was decided that the cylinder head would be replaced. This was done at 74,000 km. At 77,000 km, another top-up was needed. At 78,000 km the level had fallen to the middle of the dipstick. Reported that the cylinder head replacement didn't solve my issues. This time they wanted to measure the consumption so they filled it up again with exactly measured quantity of oil, and I had to drive at least 1000 km and then come back. After this, the official consumption was even higher than I expected (I was already prepared to argue with them if the result was "just below" 0,5/1000 that is stated in the owner's manual) - 0,6 litres per 1000 km. I just got information that the pistons will be replaced with an updated version, a 1,5 day job (under warranty). Although the situation is very inconvenient, I'm really happy that I invested a small sum to get 5 years of warranty instead of 4, otherwise I might be dealing with the costs myself (or at least fighting for "goodwill" and arguing "failed repair").

Did you try to undo through the app before or after making manual changes? I've noticed that it reports "not supported" if the expected current coding differs from its preconditions. For example, I coded in LED number plate lights through the app and right after that, I made changes to the dimming settings. "Not supported" appeared until I changed the dimming setting back to the one the app had coded. If the app coding itself resulted in "not supported", it probably failed to code something in and you should ask OBDeleven support about it.

DSG still protects the engine from too high or too low revs so it will upshift or downshift even in semi-automatic mode. 1750 rpm seems a bit high though.

My DSG is still fine since June 2016. The third clutch pack (an updated one) seems to have fixed the issue. My symptoms were exactly the same as @RB79 - everything had to be warmed up, hot weather and towing a trailer made it more likely to appear. And yes, the gearshifts were delayed, although not "holding on to the gear" but more like "until the gearbox has finished whining, you'll not get the next gear".
