I recently had my timing belt changed (amongst other small things), at the Volvo dealership. I was told that my Mass Air flow sensor was failing. I did not have enough money to take care of this. My bill had gotten up to $854 already. Long story short. Is this something that I could change and if so where is it located!?! Also, where should I buy a replacement and, should I make sure it is 'Volvo'? Thanks so much... this forum has been excellent. Thank you, again! K--
It's still expensive to buy one (rebuilts are cheaper) but it is easily replaced by anyone with basic mechanical skills- anyone able to use a screwdriver and a wrench. But you may as well not replace it until it's failed, which will be heralded by your car running like crap. Also, you will want to replace the airbox thermostat for the preheater hose to protect your new AMM. What model and year Volvo, and where are you? Then it's easier to be specific.
The labor to change an Air Mass Meter is very easy, but the price of new ones is high . This is a common failure part in the 100-200 k mile range on Volvos. Here is one place selling rebuilt units for ~$130 and new Bosch ones for ~$350. You didn't mention your car's model or year, so these might not be the right ones: http://www.eeuroparts.com/searchresults.aspx?&carid=1583&cat=1020 I have no idea how good or bad the rebuilt units are.

How is your car running now? If it is running fine without sudden upheavals in performance I would tend to be suspicious of your dealers integrity. This device does not slowly deteriorate in performance. Like others have said it is an easy item to change and makes a tidy profit for $tealeralership. Buy a good used unit and learn how to change it. Clean the connector while you are at it. Than put it in the sealed bag and have it with you in the car. If your car starts running like crap pull over and change it.
A very good point! When I had injector trouble (I had too much faith in aftermarket, it seems) the dealer condemned my AMM because it would not adjust. With the proper injectors in the car the AMM adjusted. Mike
I am amazed what some pay to have their Volvo serviced I shopped around and the Volvo car club is a good guide to pricing .Dealers scare me stiff with their free coffee and huge bills when the local Volvo specialist is a wise choice .Frankly I couldn't afford the dealer prices or a Volvo if it wasn't for the local Volvo specialists who love their Volvos and their good name ..Go check out the local Volvo boys through the Volvo car club and save ..$100.00 AU for a cam belt change over .THATS at our $ being 75c to your dollar so around $75.00 US FOR A CAM BELT CHANGE .INCLUDING BELT .As for the air mass sensor be careful dirty contacts can make it not work and a simple clean can restore it to working again .
