16485/P0101/000257 - Mass Air Flow Sensor (G70): Implausible Signal

Possible Symptoms

  • Probably no serious malfunctions
  • Loss of power

Possible Causes

  • Wiring and/or connections (short circuit?)
  • Leaks after G70
  • Mass Air Flow (MAF) (G70) defective

Possible Solutions

  • Check wiring and connections
  • Check / Replace Mass Air Flow (MAF) (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)
