Common questions
Do I code before or after fitting?
Before. Do the coding before the headlights go on.
Does it matter whose hardware my headlights use?
No. The coding here applies to our custom headlights with either our in-house or BavGruppe Design hardware.
Which values do I change in E-Sys?
In the FEM under 3061, set the front indicators' KALTUEBERWACHUNG and WARMUEBERWACHUNG, right and left, to nicht_aktiv, and their IS_LED to aktiv.
My model isn't listed. What now?
More models will be added. In the meantime, WhatsApp us with your car and headlights.
My headlights flicker after fitting. What now?
Your car needs coding from halogen to LED. See LED angel eyes or bulbs flickering at start-up.
Rather we did it?
We can code your car in person or remotely. Flickering after fitting? See LED angel eyes or bulbs flickering at start-up.
