Which Mercedes models use AdBlue?

[Scoob]

Hi all,

I've had some conflicting information on this matter. My car is a 2012 C350 CDI Estate Sport "Blue Efficiency" model. The name suggests that it might use the AdBlue additive to help reduce emissions. However, this has never been mentioned as part of my servicing to date, yet I've also been told that my car DOESN'T use it as well as that it DOES. Not surprising I'm unsure as MB's own staff don't appear to know either.

So, is the name "Blue Efficiency" the key to MB using AdBlue or not? Is there an obvious "pour AdBlue here" somewhere on my car? Should the car monitor the level of this stuff, will it tell me if I'm low, or will it just go into limp when/if it runs out?

My car is, as I understand it, a EURO5 compliant model, not the newer EURO6 the latter certainly using AdBlue. Was there some fuzzy transitional point where some cars of a given model year had it, but others not?

If it DOES need it, I'll pick up a bottle of it - it's not expensive - as it's not had any added in over three years so far - according to what documentation I have re: servicing. If anyone knows I'd be grateful.

Cheers,

Scoob.

Yours does not have AdBlue in, IIRC it's the BluTec ones that do, not the Blue Efficiency

Mines got two filler pipes. One for diesel and one for blue water.

The clue is in the length of time you have been running the car, most Adblue systems need topping up between services, contrary to the Manufacturers blurb states, if you run out of Adblue the car will refuse to start, although the system does give plenty of warning of the tank running low.

Thanks. I didn't think it did, until someone suggested otherwise. They stated the "Blue" in BlueEfficiency was the key *sigh*

and not all Bluetec's either- the 2013 Hybrids didn't

That makes sense. I'd assume that the diesel units in hybrids are tuned to be particularly clean, having the electric motor to assist and all.

My god, I must be so behind the times, what on earth is adblue???? (off to google it).

it's urea Andy which gets squirted into the exhaust stream to reduce nasty nox

I didn't know the hybrids were diesel. I thought they were all petrol?

 

[C350Carl]

Wasn't the 300 series engines (E300h) a diesel/hybrid?

As per others have said it's only BlueTec that will have Adblue. BlueEffiency doesn't.

 

[John Laidlaw]

Carl/Scoob yes the 300h were and are hybrids, and diesel hybrids which were excellent when working .....

 

[John Laidlaw]

nope

 

[Gkinghorn]

I believe blue efficiency refers to the fact that a certain% of the car can be recycled at the end of its life and nothing more .. though feel free to correct me if I am wrong. .

The Euro 6 engine will have an O2 sensor per exhaust port and piezo injectors.

Basically, if you mis-fuel it, the engine could be written off

Good for the tree's, bad for the wallet

If you have a car with add blue and have a service plan with mb you get free top ups if you fall short between services.

Off topic slightly, but what is the performance like in the 300h, being essentially a 220 engine?

goes like a rocket when you need the extra power, as the electric motor combines with the 220 diesel giving real torque and some 240hp combined.
At other (calmer?) times it tootles along beautifully and sometimes silently.
That and returning healthy MPG makes it very decent indeed.....when they work :Oops:

that's just a minor problem John

AdBlue Tank

You should be in no doubt if you have the AdBlue system, at least on the E-Class, since you will no longer have a spare wheel. In its place will be a spare wheel-sized AdBlue tank.

As stated above, applies to the BluTec models.
