Bought my first car, Leon 2018 1.8TSi DSG - any advice?

[Paul_cz]

Hello everyone, at my advanced age of 38 I finally decided to actually use the drivers license I got a decade ago and buy my first car.
I got 2018 Leon Kombi DSG. I am complete newb, so here is hoping it will not fail me and I will not fail it.
So far I have driven it to work and back couple days and around the city, had the winter tires done yesterday (they came with the car).
Now I wonder what should I have a mechanic check/do on it. Change motor oil, transmission oil maybe (It has 146000 km driven and I don't think that has been done)?
And timing chain replaced perhaps? Is there anything I should look out for, any peculiarities, anything I should do to make sure it lasts as long as possible?

Any advice would be welcome, regarding anything. I really am total newb when it comes to cars.
Thank you

Btw I know one should not buy cars based on their look (and it was not the primary thing) but I can't help it, I really love how this car looks, over its brethren VW and Škodas.

Congratulations!
Gearbox service is a must (even though VAG says it is lifetime) with fresh oil for both the gearbox itself AND the mech unit.
I also advise to get the gearbox remapped, to prevent premature failure of either the mech unit or the clutch packs.
Other then that: regular service and enjoy

gearbox itself AND the mech unit.

These are two separate parts of the transmission system that each require separate oil? (sorry I am noob)

I also advise to get the gearbox remapped, to prevent premature failure of either the mech unit or the clutch packs.

I googled what that is, but still not clear. It changes how early/late the gearbox shifts (at which RPMs) and this helps longevity? Is this something official Seat service does?

And the timing chain does not need service?

Thanks btw
