In response to a suggestion by @Oli3000 here's a list of the issues I have experienced with my early build (registers Sept 2020) Mk4 SE L First Edition estate. I have listed the ones that I am aware that others have also experienced, and I am aware that other early models had problems I haven't (mainly 'cos my car doesn't have some options/features). Many of these have been the subject of much debate in one of more threads of this forum, details will be found in there by using the search function.
I have NOT included the Infotainment Reboot issue as it is common to later build cars too, albeit fixed with software updates.
If you too have an early build SE L First Edition please add any recurrent/common SEL FE issues that I have missed.
KPH/MPH
Speedometer could not display KPH. Selection made in settings but no change to display and not saved.
SatNav could not display miles. Selection made in settings but no change to display and not saved.
Eventually a solution was developed, in my case a change of Virtual Cockpit (VC) hardware and software updates. To my knowledge not all cases need a VC change; the original in my car did not have a clock at top centre, the replacement does.
The speedometer being unable to display KPH is in contravention of UK regulations.
Adaptive Cruise Control
In general worked OK, except it would intermittently, yet often, prevent overtaking in stead of undertaking. Basically the car thought it was in driving on the right side of the road, not left; it worked absolutely fine in mainland Europe.
Fixed through software updates.
Note however, that the Owner Manual warns of occasions when the ACC can be confused, I’ve noticed it several times on long right hand bends - the car sees a vehicle in the nearside lane and prevents overtaking. Easily overcome by a tap go the accelerator pedal.
SOS errors and false calls
Several issues around this; in my case I’d get a loud ‘pop pop’ sound followed by a corruption of any [built in] SatNav directions active at the time and an alert to say an SOS call was placed - when it wasn’t!
After several diagnostics visits and software updates the SOS module was replaced and it’s been fine since.
‘Favourites’
Initially neither SatNav nor Radio favourites were saved.
Fixed through software updates.
Auto-reconnect CarPlay
For many months CarPlay would not automatically reconnect to my iPhone.
Fixed through one of the many software updates
Škoda Connect App
Early build Mk4 cars don’t have full functionality.
Cannot create a route in the phone App and send it to the car
Cannot remotely Lock & Unlock the car, but can see if it is locked and windows closed.
Fuel & Temperature Gauges Flickering
Intermittent flickering of both gauges regardless of whether headlights are on or not.
Fixed through software update.
