EDIT: Well, after calming short drive I got but then permanently ne error message on an allegedly defective bulb .. shame even the cheap LEDs from eBay all have Canbus it and therefore do not generate an error message. In addition, an LED lit up last night despite the lights switched off and the engine and after flashing even when you turn on the light, so like we know it from "cheap" LEDs unfortunately ..
Too bad, though I was still so excited at the beginning ..
