Note

♦

All test conditions and data necessary for the exhaust gas test:

⇒ "Exhaust gas test"

♦

The ignition point is determined by the Engine control unit -

J623- and will not be indicated. It is not possible to make an

adjustment.

♦

The idle speed rotation and the content of CO cannot be ad‐

justed (just checked). If there are divergences between the

actual and the theoretical values: perform a Repair Measure!

♦

The content of CO is adjusted to the theoretical value by the

lambda probe adjustment. The defects in the lambda probe

inspections are processed by the Diagnosis, Measurement

and Information System -VAS 5051A /52- and stored in the

fault memory.

♦

When consulting the fault memory, the faults detected (elec‐

tronic engine system) must be eliminated and deleted from the

fault memory.

♦

To avoid injuries in people and/or destruction of ignition and

injection systems, the ignition system cables (also high volt‐

age cables) must be turned on and off only with the ignition

turned off.

Note

The following description refers to vehicles without OBD with cat‐

alytic converter adjusted.

Special tools and workshop equipment required
♦ Gas tester - 4 components (CO, CO2, HC and O2) or GAS
