It is canbus, works without error for the 2020 vw troc but the installation was quite difficult because there is not enough space to turn it around to fit... it needs the Greek patent.

"We have seen the true light!" I'm simply amazed! The bulbs work perfectly in a 2018 VW Troc with simple headlights without a projector, even though their specifications did not mention the Troc. I bought them with reservations, checking my existing bulbs and assuming they are the same as those in the Golf. Luckily, I was not mistaken. The bulbs fit perfectly, have a nice beam, a nice white light without any distortion, no errors on the dashboard, relatively easy installation, just need a little maneuvering to fit due to limited space. We will see their durability over time and the two-year warranty. I will definitely order for the larger scale and fog lights as well.
