Note
♦ Refer to operating instructions for the gas leak detector -
VAS 523 003-.
♦ With the gas leak detector -VAS 523 003- it is only possible
to determine whether gas is present in the air immediately
surrounding the area being tested.
♦ If the gas leak detector -VAS 523 003- detects a leak, a leak
detector spray must be used to prove conclusively whether
the gas is actually escaping from the vehicle system. When
a leak detector spray is used, no bubbles may escape from
the sprayed area within a test period of 3 minutes. Should
leaks occur, these must be repaired, after which the gas
system must be retested.
