Reviews of MAGNETI MARELLI headlights

I recently bought a 2007 S4 and just went through the process of getting it Maryland inspected. Long story short, I needed to replace the right passenger headlight due to an issue with the headlight assembly. I bought [this](https://eeuroparts.com/product/magneti-marelli/LUS6751) OEM headlight and had it professionally installed at a mechanic I know where he transferred the old ballast and bulb into the new assembly. The installation was successful and it passed inspection, however, every time I start the car the adaptive light warning symbol pops up and continues to flash until I turn the car off again. Erasing the code with a scanner doesn't help and the mechanic I brought the car to didn't know how to fix it.
