Safety precautions


If special testing equipment is required
during road test, note the following:

WARNING!

Adhere to the following to avoid risk of
accident during measurements while driving
and road tests:
Only use VAS5051 or VAG1551 to read out
measuring value blocks. The tester must be
secured to the rear seat and operated from
there by a second technician.

To reduce the risk of personal injury and/or
damage of electric and electronic
components, always observe the following:
Always switch ignition off before connecting or
disconnecting test/measurement tools.
It is possible that the control module will
recognize a malfunction and store a DTC during
some tests. After completing all tests and
repairs, DTC memory should therefore be
checked and erased if necessary.
Always switch ignition off before disconnecting
