this is my first time replacing the maf, I just finished up and wanted to know if i need to do anything else after replacing it? ie reset something? I used vagcom to check 002 and the values for the new maf are 6.75 g/s @800rpm (does not seem right) after a 10 min drive the values went to 4.34 @800rpm. I could not do a full throttle run since its rush hour... but i did manage to get to get 220g/s @3840rpm.

also what does this mean
Mass air flow
2.8-5.6/10-15g/s

I already did a search and found a few more tests i could do tonight.

yeah a throttle body adaptation wouldn't hurt. I like a lukewarm engine to do this.

ok i tried to do some runs, it seems like when in Park or Nuetral the maf goes to low 4.x's g/s. i did however log boost and the actual seems to be lower than the requested. also after a few runs i recieved codes: 17521 & 17539 (sensor b2s1 and b1s1). I have already been getting those before i replaced the maf!!! could it actually be the o2 sensors? I have logged 032,115,003 can anyone take a look at them?
