Note:
All functions which could previously be
performed with V.A.G 1551 can also be
performed with the tester VAS 5051.
The control module can transfer a considerable
amount of test data. This test data delivers
information on the operational condition of the
system and/or sensors connected to it. In many
cases the transferred test data supports
troubleshooting and repair. The test data has
been summarized into single display groups
because all the information cannot be
evaluated at the same time. The information
can be selected via display group numbers.
