Once started, test modules must be completed (please refer to section 4. Working
through the "DIS testing schedule").
Premature cancellation is only permissible if a test module was selected by mistake or
if a programming error is present.
If the diagnosis user is prompted in the test module to send feedback about the test
result obtained, this must be followed.
Your "own testing schedule" is completed when the cause of the fault has been identified or
when no function or component faults can be detected using the test modules in the testing
7. Use of control unit functions
The <Control unit functions> provide the option of fast access to known diagnosis
functions. In addition, the fault memory details stored in the control unit can be read.
Using the control unit functions is not however a substitute for performing the test modules,
as the control unit functions ...
... do not contain detailed information or instructions.
... do not contain all diagnosis and testing options for the functions and components.
8. Observing current technical information
In addition to the diagnosis programs, information about current technical problems are
published through special media and systems (e.g. Service Information bulletins or PuMA
actions). It is essential that such information is also taken into account when performing
vehicle diagnosis. At the latest when replacing components, it must be checked whether
any additional information is available.
If the repair/servicing actions recommended in the test module differ from the current
information, this should be noted in the remarks field on the warranty or goodwill claim.
9. Quick delete
After identifying a fault and repairing the faulty components, all faults stored in the vehicle
must be cleared with the <Quick delete> function.
As not all fault memory entries are shown by the service diagnosis programs or a
summary of fault groups is given (e.g. bus faults), only the <Quick delete> function
can guarantee that all faults stored in the vehicle are cleared.
10. Reporting faults in diagnosis programs
If during diagnosis faults are identified in the diagnosis programs or documents, these must
be reported through the known feedback channels.
Benefits for the dealerships in the BMW dealer organisation
System-based diagnosis is the most important tool available to workshop staff in the dealer
Increasingly complex systems and their networking within modern BMW automobiles make
fault elimination without electronic diagnosis systems increasingly more difficult or even
Correct diagnosis application gives the dealerships in the BMW dealer organisation
important competitive advantages. These are described below:
The high degree of networking between the increasing number of control units means
that when faults occur, the relationship between fault cause and effect can no longer
