This bulletin applies to 2010 Audi R8 vehicles. The radio may turn on and off while driving, the clock in the radio sporadically may not work and the door locks may actuate while driving.
The cause may be due to sporadic disruption of the S-contact due to lubricant on the contact surface.
The S-contact has been improved with a modified lubricant that has better electrical conductivity.
According to Audi, the solution involves replacing the ignition switch with P/N 2804 1900.
