code: P0101 or 16485

hi, i am on occasion getting this code. i clear it and it stays away for a while. comes back every so often. maybe 1 time a week or 2 weeks.
as i read the dtc code meaning (16485/P0101 - Mass or Volume Air Flow Circuit - Range/Performance)
what does it mean. i have replaced the maf sensor 2 times because of this. i dont want to spend more money on yet another maf. anyone can help me?

see sig for car info.

thanks

Could very well be an air leak.

Check the connection of the air intake hose into the Intake manifold assembly. The metal collar has a habit of wearing away the nubs and it leaks.

P0101/16485

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)
