mass air flow sensor

so ive been looking around online and i havent been able to find anything on locating or changing the mass air flow sensor...can anyone send me in the right direction or give me some advice?

thanks

What engine? Are you asking where to buy the part or where is it on the car?

sorry, its a 2000 golf w. 2.0 and im asking both,....where is it located? is it easy to change? wheres the best place to buy it

thanks

It's bolted onto the outlet of the air filter housing & has an in-line five wire connector. It is fairly easy to replace, but if it has set a code you will need a scanner to reset.

If you have less than 70k miles than its covered under vw warranty.

is the dealership the only place i can buy it from? i checked pep boys and they cant get it.

There are lots of aftermarket vendors online, do a google search on "VW MAF". VW's price has come down alot in the last couple years, so it's not too bad to buy it from them.
