For some newer European vehicles such as BMW, Mercedes, Audi, Volkswagen, etc, they all have a very smart and sensitive on board computer, OBC. The OBC will notice the car led bulbs because LED bulbs have lower wattage comparing with original fillament bulbs. In order to eliminate the flash problem and bypass the OBC error showing on the dashboard, you will need to add resistors.
