I bought a Skoda Octavia Elegance 148bhp 2013 with 6 speed dsg, with 55k miles on the clock, from a Skoda dealer who had run it from new. Last person driving it was sales manager’s wife. I wasn’t aware that dsg needed servicing every 40k until mine had done 90k. At that point I queried when the last dsg service was done with the dealer but there was nothing to say ‘dsg service’, just oil change. The service rep guessed at when it was done but it wasn’t close to 40k. I noted that there was no dsg tick box in the service log book either. I never had a problem with the car, it was fantastic and took me and my family to Spain each year with ease.
I’ve since traded in for a Passat GT estate with same engine/dsg gear box at 48k, the vw service log book does have a dsg tick box but wasn’t ticked. I had the service done myself but checked with my trusted mechanic, of 10 years VW experience, who advised that it isn’t critical but should be done within about 10k of 40k. Better safe than sorry of course and personally would get it done on schedule.
My point really is that I too have read so many bad reports of these gearboxes and rarely positive reviews from normal drivers. I treat my car well and look after it and never had a problem with the gearbox.
i expect your Octavia will serve you very well indeed, it’s a great car.
If you were wondering why I traded? I needed a bit more space for growing kids when driving to Spain.
