Hi Davy, Thanks for the quick response. I have serviced the car in company last week, and they scan the car with their system after I told them the issue, but no issue found, Im in doubt why the scanner didnt detect the issue since there is a warning sign in dashboard as well :) Do you have any thought? I have not used any stickers for sure, though its not possible to check inside of just behind the rear mirror since it seems to be permanently fixed rit.
