Hello Guys and Girls Lurgs here and today how to top up the AdBlue on a
Mercedes S-Class. Now AdBlue is an additive which you add to a special tank
and it gets sprayed on the exhaust basically to cut down on harmful
emissions. Now on the S-Class this is a right pigs ear of a job really.
They obviously expect that if you have got loads of money you would never want to do it
yourself and you take it into a garage. Now I advise that you buy a good load of
this stuff because it is much better value to do that and you get a spout for
it but on this video I'm just going to use this small portable one which I
bought from a garage and you can just keep this in the boot for any
emergencies because the car will not run if the AdBlue runs out! So this is the
S-Class here with the Bluetec badge on the back and here is my bottle of AdBlue.
Right so here we go, you can see why this is a bit of a pig of a job
especially if you are not very strong. Right so we are in the boot \ trunk and you basically
need to take the spare wheel out, no other choice. So just turn this
anti-clockwise to release the wheel and then you are just going to have to use a bit
of your brute strength and just lift this spare wheel out.
Luckily I have got a bit of muscle so I just lift that out and place it down carefully, and this is
where the AdBlue tank is. So it has got a small cover on here so just turn this
anti-clockwise not far and this is actually where the AdBlue tank is.
Just down here so as you can see not an easy thing to top up like screen wash fluid,
or filling it up with diesel. It is a bit of a pig of a job
especially if you have got loads of stuff in the boot \ trunk. Anyway so I have got this
portable container it is only 1.5 litres, very expensive to buy like this.
So you need to get the blue cap off and what you need to do with this one
you just push it down very gently and just turn it clockwise because this is
actually a thread system so just keep turning it until it won't go much
further don't over force it and then what you need to do after that is you
lift the bottle up in the air and then it pops and then you'll hear the
AdBlue actually filling up into the tank.
So you can hear it emptying
I mean this is a very nice neat way of topping it up but quite an expensive way
because really you want the bigger containers so just give it a little
shake there and then to release it just push it back down and then unscrew anti-clockwise.
And there we go just make sure the bottle is empty just by
chucking it in the back of the motor and this is definitely empty so job done, so
let us put the screw cap back on.
And just the other small lid.
Just a short turn clockwise, now we need to lift the spare wheel back into the
back of the motor, and then just make sure you put the holding panel back on
which you just screw in clockwise put it in the right way up which does help Lurgs! Here we go.
And that is it, you can just put all your stuff back in the boot \ trunk now. So as you can
see not a particularly easy job I mean if you are not very strong then it is going
be pretty tricky but there you go. Job done the End. Hope this has helped
somebody out there if it has please subscribe I really would appreciate it.
Thanks Guys and Girls
