To evaluate air flow you need to look at egr (exhaust gas recirculation) and maf (mass air flow). Minimum then off is about 300 and maximum then on is about 485.[font=&quot] [/font] and also the turbo test (test no.

Unplug the maf sensor’s electrical connector. On most current vw/audi engines, the actual maf value can be found in group 002, field 4 or group 003, field 2.

I would say its possible yours is a shorted maf but first i would check the volts at each wire, key on, and then running and see what it says.

Before going into detail on what will happen when you disconnect the mass airflow sensor it is important to understand what it actually does. Video on how to investigate and repair maf issues on vag group vehicles.

Relay at ecu is number 219 so i been told. If they read as they should then i would try to beg borrow or steal a known sensor to try.

On Most Current Vw/Audi Engines, The Actual Maf Value Can Be Found In Group 002, Field 4 Or Group 003, Field 2.

One of the most commone failures on 2000 and new vw and audi cars is the maf sensor. As stated before, the mass air flow test is a very easy and simple test but there are a couple of things that have to be done. This techtip describes a method to diagnose a failing mass airflow sensor.

Here's A Good Sanity Check For The Status Of Your Maf.

Then (as now) it is ok at idle. Do not replace maf sensor for the faults described here. after installing the new battery and clearing the p2196 code, i drove it about 10 miles under varying loads and speeds to see if the code would reappear. The maf sensor?and is there any fuses to check?

Set Your Dmm To The Ohms Scale.

Connect an obd2 scanner and check the live data from the maf sensor on idle. Vehicle may idle rough and stall. What does mass air flow sensor do?

And Even Show Peak Values During A Road Test.

This has been carried out on my 99 audi a3 tdi (ahf engine)i have used vagcom also k. Well, you could certainly use vcds to watch what the ecu is seeing from the sensor, but without some reference, i.e. Maf sensor, detection at low battery voltage too sensitive causing mil on with faults p0101 and/or p0102.

Testing The Maf Sensor’s Hot Wire:

To evaluate air flow you need to look at egr (exhaust gas recirculation) and maf (mass air flow). Easily be accomplished with a tool such as vcds which can log graph, figure a. O_o it's a vw, after all.
