Affected Vehicles

Condition

The customer may report that the daytime running light LEDs in the headlights have slightly different shades of color. There is no related memory

entry.

Technical Background

The minor color differences of the LEDs are caused by the coating of the blue LED with yellow phosphor. This coating is necessary to get white

LEDs.

A permissible range of white for the road traffic is defined by law (Figure 1, Area 1 within blue dotted line).

The LED manufacturer sorts the complete production volume according to even smaller color ranges (Figure 1, Area 2 in black grid).

To get the fewest possible color deviations, Audi uses only part of the manufacturer's already limited range and thus only a small section of what is

legally permissible for road traffic (Figure 1, Area 3).

In production, a finer color selection is not possible; this can lead to minimal color differences. This is normal.
