Vacuum Gauge/Economy Meter: Testing and Inspection
Testing readout for economic driving (ECONOMY)
Special tools
Tester for vacuum 0-1000 mbar (116 589 25 21 00)
Operation
The indicator is connected to intake manifold by way of a vacuum line and indicates the momentary fuel consumption in dependence of intake
manifold vacuum.
At high intake manifold vacuum the needle is in black field of readout (fuel consumption low), with decreasing intake manifold vacuum the needle
will move into red field. The momentary fuel consumption increases.
On stopped engine the needle rests in red field against righthand stop pin.
Vacuum <= 0.08 bar.
