if (window.showTocToggle) { var tocShowText = "show"; var tocHideText = "hide"; showTocToggle(); } 16485/P0101/000257 - Mass Air Flow Sensor (G70): Implausible Signal

Possible Symptoms

• Loss of Power
• Erratic Idle

Possible Causes

• Mass Air Flow Sensor (G70) faulty
• Air Leak(s) after Mass Air Flow Sensor (G70)
• Intake Air Filter dirty/faulty
• Ground Spots corroded or Paint Residue
• Wiring and/or Connections from/to Mass Air Flow Sensor (G70) faulty

Possible Solutions

• Check Intake Air Filter
• Check Mass Air Flow Sensor (G70)
• Check Ground Spots
• Check Wiring and/or Connections from/to Mass Air Flow Sensor (G70)

Special Notes

• In MY 1995-2002 (?) in Europe at VW-diesel-cars G70 had the bad reputation of slowly losing his performance, causing loss of power. It's not a matter of defective or breaking down, but it is filthy / dirty (not easy to clean). You can check functionality by making a log in [01-engine], [meas.blocks-08], group 003 (3e gear, full throttle, from 1700-4000rpm)
