Hello, I have an audi A7 it comes with led headlights and my issue is that the turn signal blinks but not all lights light up. Drl works perfectly as well as low and high beams. I get a code 03848 and computer says "Right front turn signal- Electrical error in circuit". Any info and help appreciated. Have no idea where to look or if this is fixable.
It is a defect inside the light assembly. The official Audi response is to replace the unit.
However, this kind of defect is fixable. Unfortunately it involves removal of the light assembly, opening it and finding the defective component on the LED driver circuit board. All you need is a Voltmeter. It may be a bad transistor, a bad IC or a broken PC board trace.

Does it involve taking apart from the back or the lens?
