Dreaded Adblue countdown

[OneForTheRoad]

It's more prevention than cure adding it tbh. But kettles do decale , make of that what you will.

Anti crystal was brought to market long after the boffins realised ad blue had it's issues with gout.


Would I spend £1000's trying to fix a system that reduces Nox by 1.8% over a diesel that doesn't care , No . Id delete it from the ECU .

We only ever fill with the drreaded devils juice from the pumps at the HGV bunker pumps on motorway service stations.

Not quite sure where you got that little gem from but from a car tech site ..
The fluid reacts with the harmful NOx emissions to create nitrogen, water, and carbon dioxide – reducing emissions by up to 95%..
...and NOX is nasty stuff. When you think about it no one would have bothered with all that tech for a sub 2 percent gain.

How AdBlue Reduces Diesel Emissions - Atmosfer Machinery

One of the most effective solutions to meet these standards is AdBlue, a Diesel Exhaust Fluid (DEF) designed to significantly reduce NOx emissions.

Yes sorry Sherlock it's 0.08 euro 6 Vs 0.18 euro 5 for nox emissions. I knew I'd read 1.8 somewhere a long long time ago. Thanks for that .

Euro 5 emission standards for diesel cars
Carbon monoxide: 0.50g/km
Hydrocarbons + nitrogen oxides: 0.23g/km
Nitrogen oxides: 0.18g/km
Particulate matter: 0.005g/km
Particulate number: 6.0×10 ^11/km


Euro 6 emission standards for diesel cars
Carbon monoxide: 0.50g/km
Hydrocarbons + nitrogen oxides: 0.17g/km
Nitrogen oxides: 0.08g/km
Particulate matter: 0.005g/km
Particulate number: 6.0×10 ^11/km

It might reduce it by up to 95% if you take your car on a track day and thrash it around Silverstone, but pootling down to the shops and back, not much difference at all.

Now, that's not a scientifically qualified assessment.....

Ad blue simply reduces Nox emissions, not overall emissions, the dpf and egr play their part in that. Your ad blue being deleted will just apply to the nox levels and probably read the same as a euro 5 . Same as Alfa's . Possibly even less .

Mine may be Euro 5.....but it produces Euro 6 levels of nox or less.....which is why it's ULEZ compliant. So deleting the Adblue on an E6 car could make its nox levels worse than my car!
That said I too would delete the Adblue to avoid the inevitable big bills......but then I would never buy a Merc with it in the first place.
I can't understand why other, allegedly, worse quality cars, can make Adblue systems that function perfectly when the mighty Mercedes can't. I've never even seen a thread about Adblue over on the ALFA site.

I wouldn't want to own any MB car equipped with the AdBlue system. As if the DPF isn't bad enough on its own. To my mind, MB's AdBlue is a ticking time bomb.

And to those who say 'my AdBlue Merc did 100,000 miles with no issues', all I can say is that soldiers have been known to run through a minefield and come out unscathed at the other end - but no one in his right mind would do it if they didn't have to.... So, just consider yourself lucky.

Personally, if faced with this situation, I would trade-in my AdBlue MB car asap, even at a loss (which should really be regarded as 'cutting your losses'), then buy either a petrol MB or a non-MB Diesel car. But I wouldn't delete the AdBlue just so that I can keep on driving my Merc. Personal opinion.

I'm looking into it this year , possibly an e300 or a c43 . Something around 35k . I'm waiting to see what happens with this ved come April, some say it's gonna double,but I just see 2.6% price rises.

The main difference between Euro 5 and Euro 6 is that: Euro 5 engines focused largely on carbon dioxide emissions (CO2), while Euro 6 is primarily focused on reducing nitrogen oxide emissions (NOx).

It'll be interesting to know what exactly ulez focus is on with regards to emissions is it co2 or Nox . Or both . Something else for you to Google later on. Please report back with your findings.

Carbon does not come into it. ..just NOX and particulate matter. Ignoring the obvious climate issues carbon has no effect on human health or air quality in cities....and that's all ULEZ cares about. So as much as an icebergs melts and a panda dies each time you start your M156 engined car....its still ULEZ compliant!

I miss butterflies and wasps . Thanks for the info . Luckily for me I don't live near any ulez controlled areas ,so won't be entering any anytime soon.

 

[ALFAitalia]

Me neither....

I do live in a ULEZ area, but luckily for me a considerate boy-racer in a Ferrari kindly wrote-off my non-compliant EU5 Kia Diesel while it was parked outside my house, days before ULEZ came into effect... Now replaced by a petrol Suzuki
