To answer the question I would think that 90 percent of Octavia Mk4s are receiving visible faults.
Mine is a 2021 vRS Combi 21.5K miles.
When I first drove the car the handling and steering were a bit vague. I had it four wheel aligned both rear wheels were tracked correctly but pointing slightly to the Left and the Front Right wheel was toed in too much. I got rid of the stock Bridgestones and fitted 4 Michelin Cross climate 2 tyres as we were heading into winter. The handling particularly the steering was still vague. To be honest I don't think that Cross Climate 2 tyres are well suited to the Octavia MK4.
In March I took the car to a specialist and got (Factory) Traffic Awareness fitted and the Farting Hippo Exhaust Soundaktor turned off.
I've just fitted Michelin PS5 tyres on to OZ Racing wheels the car drives a whole lot better now.
Its just 3 years old and I have extended the warranty for 2 more years as I feel its likely to suffer some sort of expensive electrical / software problem. It also comes with 2 services, MOT, AA Breakdown.
I've just had to get the wheels stripped and powder coated. The inside recess behind the spokes was lacking paint, consequently corrosion and peeling was underway. Stone chips according to Skoda!
Currently I get these errors:-
Wipers Failed But everything seems ok.
Crash Display in RED in place of the rev counter warning
Limited Front Stability
Lane Departure error
The above clear after a stop, park and re-start the car.
USB media player stopped working after the latest upgrade over the Internet its now working, RESULT?
