How strange, I have also had similar issues with 2018 SEL DSG.
The car was serviced and passed MOT by Mitchell Skoda Chester in February 2021. It was out of warranty in March 2021. The following issues occurred;
Airbag Warning Light
Central Locking Issues
- same as author - was having issues getting into drivers door and had to open from inside.
Took vehicle in and was advised that a part is required for airbag. In addition, a new steering wheel needs replacing as the horn and controls were not working. Also found issues with drivers side lock which needed replacing. In addition, they stated that the stop/start ignition button needed replacing!
I was initially quoted £800 to replace parts in which x2 parts needed to be ordered outside of the UK, however, they stated as ‘gesture of goodwill’ this will be offered for £250!
They have stated that they need to keep hold of the vehicle as cannot be returned until the above has been repaired, and are offering loan vehicle.
Very disappointed that these issues have occurred with a vehicle only 3-years old and I was expecting better reliability from Skoda. I am unsure what the total costs will be including labour but will update this forum. Looks like there is a trend with 2018 DSG Karoqs!
