Maybe he had 1 eye shut........... glad its all sorted now mate!
Just bear in mind you may also have a faulty brake light switch, Just get it checked on vag com
It may still be the bulbs, I had both dip beams go simultaneously on an old Peugeot I had, apparently it happens due to the extra surge of power going to the good bulb when the other one blows. If it’s the brake/tail light (with the single filament) you could try the reverse of fog light bulb to check.
