NHTSA's summary

Supersedes Technical Service Bulletin Group 91 number 10-70 dated October 26, 2010. Sequence of error messages are seen on the radio display screen after a CD was loaded into or removed from the internal CD drive. "Drive defective. The error could be corrected by resetting it (see radio system owner's manual). Otherwise, contact your Audi dealer." "The CD-drive is damaged and was therefore deactivated." The CD drive cannot be selected in the Source list and is described as "damaged." After the ignition is cycled or a radio reset performed, the CD drive is fully operational. DTC 00468 (CD-ROM Drive -R92- Faulty) is stored in the radio (address word 56). The DTC will be sporadic if the ignition has been cycled or a radio reset performed and will automatically be cleared after 40 ignition cycles without a reoccurrence. Only vehicles with the CAN-based generation 3 radio (Concert (PR 8UQ) or Symphony (PR 8YN)) are affected.
