hello my name's Mel welcome to my world and for those of you that are new to my
channel I'm currently turning this Mercedes Sprinter into an off-grid go
anywhere sleep anywhere kida stealthy camper van so if that's something
that interests you then please do consider subscribing to my channel now
those of you that are regular viewers to my channel will know that I've had no
end of drama with more Sprinter of a gearbox problems of an engine problems
engine management lights coming on nearly every time I Drive it and today
is no different that they I've got another problem me energy management
lights come on again but luckily well not luckily but guess it is luckily it's
all a good thing I've got an engine scanner so as soon as I get back I'll
just simply plug me scanner in and it tells me what today's problem is I'll
show you it's actually weekly so today I've got a mess of volume air flow
sensor a circuit range performance in other words my mass flow air sensor
probably needs cleaning fingers cross that's all it is it just needs a claim
and I thought I'd make a little video about this because it is important to
clean your mess flow air sensor pretty much every time you change your air
filter you should try and make it a regular part a service in your vehicle
especially in the slightest bring up because they are so fussy something's
not sending the right signal you will get your engine management like come on
so if you do own a Mercedes spring out or highly recommend kicking yourself one
of these because these has proved invaluable I'll put a link below in the
description well anyway enough erect it's not a
sales pitch it's a recommendation but if you do click the link in the description
I don't make a little bit of Commission off of ebay not a lot but it all helps
anyway right so mass flow air sensor very important you clean them especially
if you've got an old vehicle that's done a lot of miles and this sprint is no
exception it is a 2008 and it's done nearly hundred fifty thousand miles so
I'm not overly worried the chances are adjusting these cleaning so I thought
I'll show you how to clean it and this applies to most vehicles
mess flow air sensor is really easy to find it's usually between the air filter
and the inlet manifold it all goes into the inlet manifold and it's usually not
far from the airflow the here air filter so I'm going to spin this thing around
face it towards me carriage I've been upon it and this look and see
if we can find the mess fly this inside so this is what the splinter looks like
angered upon it massive air filter there and I think you'll find if you've got a
Volkswagen crafter it's pretty much looks the sign underneath this die the
engine compartment is very very different but from what I've seen
they're pretty much the same now first thing you need to do is disconnect your
jumpstart cable this simply works like this and this is live there this is for
when you need a jumpstart your engine or you want to help someone else jumpstart
theirs they're simply clips on the side you can see I forgot to every connect
that last on my piece apart and all that dis apart quite a few times all right so
there's me mess flow here same sound like I see connects you directly to my
air filter push these little lights in and push forward and then back usually
they come on plug quite easily same with this one pushed a little login push
forward and then back
so this is really easy to get this off sorry about background noise
pulled out like that and there you go she's out so now I've got to take this
off and this is your mass flow here since I here I'll need to remove this I
need to get to the other side of that to blow some cleaner for it be right back
so to remove the mess flow air sinks I hope we got a doing is undo these total
screws here very simple they make it simple to do because really you should
clean them right yeah some mechanic say that every time you change an air filter
like a city especially in a high mileage cars should always clean what this
sensor does it lets the computer know how much air is flying fro flowing
through that way so the air comes in it warning through here goes through the
filter and cleaned and it goes through the mess flow air sensor and that's when
that kicks in that tells the computer on the vein how much he's actually flowing
long gone are the days of carburetors this boy here called Volkswagen things
were so much easier guard on here this has got a guards we can't get to it so I
need to just pry that off
so simply remove this guard and that in there is your sense of right down inside
in and don't touch it don't ever touch that sense of your fingers it's a bit
dark in here let's bring you out what sort of remove the little cover and this
is locking directional covers were it directs the ear in a certain direction
it's a bit dark down there so get me touch fine light this up so
you can see what's down there there you go now you can see the sensor in there
very sprite and cleaner in there and whatever you don't don't touch that you
mustn't touch it I can't stress it enough and you mustn't touch it with the
end of this there to clean it I'm using mess flow air sensor cleaner quite
simple really available for you bye I'll put a link in
the description so all we do is get our nozzle I'm it Oh neither forgot me reg
I'll put a cloth the other side to catch the residue bit cleaner and simply spray
in there for about 10 to 15 seconds leave it for about a minute or so and in
repeat Sprite 10-15 seconds leave it to soak for a little while and spray it
again I thought I saw we don't write in there leave it for a little while let
that evaporate and do it stuff for about a minute but we'll skip that bit anyway
to get in for another 10 to 15 seconds so that's what we do so I'm going to
carry on doing that come right back to you alright so now
I'm satisfied s had a really good clean I need to pop me little cap back on and
it's got little lugs see these little lugs standing up there a lot two little
prongs let's to make sure you get this back in the right place back in the
right place like that so that's all put back together
that's just matter assembling it put it all back together and put it back on the
rim simple see a real simple job now there is a rubber o-ring inside here
just have a quick look at that make sure the o-rings all good
you can even smear a bit of silicon silicon lubricant around it you know
I've got some actually I've got some for me diving equipment that's gone real
easy so we won't need that if you do have trouble don't bullshit
twine lubricate the o-ring you can even use grease if you want to but silicon is
about line the arms up so I'll simply put it back on line the holes up and put
the screws back
these don't have to be tight they literally just hold this in place the
o-ring creates the seal so don't over tighten these and strip the thread out
like so many people do and I'll show you an example as well with that because it
is only plastic literally just do them up you don't know how it's drying on it
if you look at my airflow a box if you fill the box you'll see there screws
missing and this is where people in the past of over tightened in and strip the
frayed set up I really need to replace these actually that's another job for
another die well let's get these back on the vein and I put this back on the vein
it's quite simple make sure these wires are clear let's see what I'm doing
please prongs ear simply line up with two big lugs on the back there and this
simply fits into a hole that comes out about here just an air channel this part
just goes into an ear channel driven past this blood and
I'm screwdriver in there
pop blows back on don't leave screwdriver they pushed it back down and
I see it's all back together see a simple that was one screwdriver for
Jubilee clips one screwdriver for the two screws that is it be a cleaner done
hopefully fingers crossed that's all I need to do so what I need
to do now is go back in the cab delete that error code from the I costs off
scanner they take you for a test drive that's next job I'll show you how to
delete the code so I'm back in a vein now to delete the full code I need to
simply turn my ignition on I'll bring you around I'll show you what I mean so
I turn the ignition on one click and then again so now my ignition is on but
not running I don't start the engine I didn't go to my car soft and it says you
can see there's a fault code dude let me put you on this tripod so there's me
font Cove it's still showing up on there so now I'll press the back button it
brings me back to this menu and you can see the next down it says read cozy
arrays codes so I'll click these buttons here down so you raise close codes click
a button and it should say mission we like your diagnose there will be raised
are you sure yes continue make sure the ignition is on
with the engine off which is talking to vehicle please write the Rose cut
command is okay so now many codes have been erased so now on it at those start
my engine died for a little spin we're in a block now I'm not going to film
myself whilst I'm driving there in the block I'm a professional driver I've got
a clean license and I'd like to keep it that way and I do think that filming and
driving it can't be legal can it surely and besides the local Bobby is a friend
of and I think it'd be rather embarrassing
if he was to see me filming and driving at the same time so yeah I'll be right
back once I've taken this baby for a spin me in a block well I'm pleased to
say it purrs like a kitten pulls like a trying just like a sprint I should I've
got it out to Tim which I've done about ten fat's in fares and I've time head
ten miles got it out to temperature no morning lights drives absolutely
perfect I'll just show you what I mean there you go just to show you it's
absolutely perfect again so I'm really pleased actually I'm over the moon
because I'm math ness airflow sensor from beside YZ is 270 quid plus V eighty
that works out about three hundred pound soft side meself three hundred quid
while spending 12 quid on a cleaner cleaner so I'll put a link in
description to where I've got this off eBay it's well worth doing every time
you change the rear feel or apparently you're supposed to clean your mess mass
airflow meter as well also I'll put a link in the description
to where I got this I cough I cast soft car scanner and it's been invaluable
this thing so I'm really pleased I got that I will put links in the description
