A lot of people split in opinion on this one. Some will say to clean it yourself (only use CRC Mass Air Flow sensor cleaner) with this:

Others will tell you to only have a Volvo repair specialist do it. If the MAF gets damaged, new ones are very expensive and remanufactured ones sold at auto parts stores for $100-140 are... well... remanufactured (probably would work fine, but who knows).
A Volvo repair specialist whom I have dealt with before is adamant about people not pulling the part themselves and spraying the cleaner on.
I have read not to spray the cleaner directly onto the sensor, but to spray above it and let it drip down gently onto the sensor.
In any case... on my car, the MAF has one ring clamp to be loosened on the output side, and 2x #25 torx screws, anchoring it to the air box, to be removed. Pull it out from the air box, keeping in mind not to lose track of the o-ring gasket sitting in the air box port. Then gently and firmly pull it to separate it from the air intake tube (might want a second pair of hands to hold the intake tube)... don't pry it out from the intake tube, a steady gentle pull will do the trick.
As stated above, be very careful when spraying the cleaner on the sensor, trying not to let the stream hit the sensor directly... those things are damn sensitive. Don't use anything else, just the cleaning fluid... no towels, q-tips... nothing. Use just enough cleaner to allow it to self-rinse and then air dry... back in the car it goes.
Use caution when re-applying the torx screws to the air box... they are easy to get cross threaded in the plastic of the air box. You can end up with a loose connection to the air box if that happens.

Here's what you are looking for. If yours actually has 4 'star' screws on it, it's a different model than mine. Mine has 2 #25 torx screws (6 point) anchoring it to the air filter lid, and two smaller 5-point security screws (have center pin) which anchors the sensor to its housing.
Also, don't forget to disconnect the electronic connector before removal. For the lower of the two torx screws holding it to the airbox, I used a universal joint socket to get at it from an angle. You'll need that get to the screw straight on or else you are almost certain to cross-thread the screw when you put it back on.
And the location on the car (example image is of a 2001 S60):
Last but not least. My disclaimer.
I gave some pointers based on my own experience, but if you screw up your car it is your fault!

thanks
Thank you for your time.
Well, I think the reason I was having trouble ID'ing it becasue mine seems to be a DENSO brand, and has no screen. I found a vid on youtube of a guy cleaning exactly the one I have, and this is the match for the one I have in my 2001 S60.

For $7 I got the job done and much improved, the is, no crazy fluctuations while in idle.
Now how much would my mechanic have charged me for this?
