Here are the steps for changing
your air mass meter ;
On the VW Sharan, the air
mass meter is situated on the left of the engine bay behind the airbox.
It is
bolted onto the airbox at one end with 2 x 8mm allen bolts and clamped at the
other end onto a plastic air pipe with a clamping ring.
1.
Unplug the wiring from the meter by squeezing the clips wings inwards and
pulling up. Do not pull it by the wires.
2.
We will start off by removing the
plastic pipe at the back of the air mass meter.
When you push the the 2 clamping ring wings towards each other, the diameter of
the clamp increases allowing
you to push the pipe off the end of the meter. With
your right hand take your pliers and put them over clamping ring� wings,
push the pliers together and as the ring opens, separate the pipe from the meter
with your left hand.
You can leave the clamping ring in place around the loosened pipe.
3.
The next thing to do is to unclip
the top off the airbox and turn it over.
This will be easy now you have removed that plastic pipe, and noe of the other
pipes on the airbox will need to be removed.
Turning over the airbox lid at this
point will make it easier to remove the 2 x 8mm allen bolts holding the meter.
There are 2
clips holding the airbox lid in place, one at the front and one at the back.
Locate one of the clips, put your hand down there and feel the bottom of the
clip.
If you pull the bottom of the clip upwards, it will release the top of the
clip. Push the top of the released clip
away from the airbox lid and repeat with
the other clip.
4.
Now you should have easier access to both of the bolts holding the air mass
meter.
Undo the 2 x
8mm allen bolts using your 8mm allen key. Once removed make sure you put them in
a safe place.
The meter should now separate from the airbox, make sure that you
retrieve the large 'o' ring
from the outside of that end and fit it to the new
air mass meter.
5.
Fitting the new air mass meter is a direct reversal of what you have just done ;
a.
fit the old 'o' ring onto the new air mass meter
b.
bolt the meter back onto the lid of the airbox
c.
clip the airbox lid back on to the
airbox, making sure that the
panel filter is seated correctly
d.
Connect the plastic pipe back onto
the other end of the air mass meter,
making sure that the clamping ring is
securely in place
e.
reconnect the wiring plug onto the top of the meter
FINISHED.
It has been suggested that the battery power should be disconnected for at least 30 minutes so that the ECU (cars computer) will reset.
This will ensure that all the old ECU settings are wiped and it will then start up again using the new air mass
meter readings.
This could be done at the start and remain disconnected during the new install
to save time, or it could be disconnected for 30 minutes after you have
finished

I'm not going to ask the obvious question here.
I'm going to assume that I'm confused, lost and possibly not quite together upstairs. I may then reconsider my Volkswagen Nissan Navara Sharan purchase and ask for my Commodore back. At least that didn't confuse me - either it won on the mountain, or them blue things did.
If you meant to mention that the VW Sharan is built exactly the same as a Navara and its engine bay is close enough match so that us Navara drivers can follow these instructions, I'll be a lot less confused and possibly even feel like I'm maybe not as lost as everyone tells me to get.
odds are "game" is a spam bot. posts seam to be cut and paste. note the advert in the sig.
usually nissan maf sensor just unscrews. its easy to get to, just remove plug and cover. probably a couple of torq screws holding the sensor in.
if you buy a new sensor make sure you buy just the sensor and not the whole assembly.

I dont know, who is to say (I am assuming) he hasn't changed a AFM on a Nav but has on a VW.
If there is spam, I will ban.
