New audio test CD for complaints about sound system playback
All series
Situation:
In case of customer complaints about sound quality when playing CDs or DVDs, it can be
extremely difficult to diagnose whether it is a problem with the drive or a problem with the
disc itself.
This is in part because customers are increasingly using discs of poorer quality (e.g. self-
recorded CDs), which either cannot be played or can only be played poorly.
To help you distinguish, an audio test CD is now available.
This audio test CD should be used to analyse the following complaints on the customer's
vehicle:
-
CD/DVD not accepted
-
CD/DVD jumps
-
CD/DVD cannot be read
-
CD/DVD operation interrupted permanently or intermittently
Note:
The audio test CD contains a track with built-in faults, but which the sound system
should play back correctly.
Affected
vehicles:
All model series with original BMW/MINI audio systems with CD/DVD drive or CD/DVD
changer.
Procedure:
Insert the audio test CD in the drive for which the customer has complained about the
sound quality.
Important:
The audio test CD provides a sensitive reference.
For this reason, comply with the following guidelines:
-
Do not touch the CD on the playing surface, only on the edge.
-
Do not stick labels or write on the CD's surface.
-
Do not expose the CD to direct sunlight or high temperatures.
-
Only remove the CD from its protective cover for immediate use.
Play track 12 of the audio test CD and then perform the following fault analysis:
•
If no faults can be detected in the sound quality, there is no fault in the audio system.
Replacing parts will therefore not achieve the desired result and must not be
performed.
•
Check whether the disc used by the customer is the cause of the complaint.
•
If there is interference or if the CD jumps when track 12 is being played, the audio
system / drive must be replaced.
Note:
The new audio test CD 01 99 00 33 475 does not supersede audio test CD
