Anyone ever heard of or tried these versions of OEM lights. Says they come with auto levelling motors built into the lights & HID lights fit straight in them with no error codes. I'm very sceptical as I thought the auto levelling sensors needed to be placed at front & rear of the car. Plus no error codes when fitted. Here's the link anyway.
