Ad blue reset ?

[Shreknomore]

Hi all
My adblue has not reset after refill , is it possible through one of the systems on this thread?

 

[Dellmassive]

Did you fill it with the correct quantity requested on the dash display?

What did it ask for and how much did you put in?

 

[Wildcamper]

Take it for a drive. Sometimes my rest takes a while but taking it for a drive gets the reset going. My experience as anyway.

 

[Shreknomore]

Thanks for the reply. The dash said 2.75 gallons but I Might have put a bit much in. I have managed to get some out and done about 200 miles since, motorway and around town but it's down to 550 till no start and not reset. Was counting down fine till the 1000 warning. Get a bit of clenched buttock syndrome now.

You might need to suck some more out.

The sensor is ultrasonic at the bottom of the AdBlue tank and when you overfill it the filler neck fills up with liquid.

As you start driving the liquid in the filler neck starts dropping down but the ultrasonic sensor doesn't see the overall tank level dropping so it flags a fault.

What's the level of AdBlue is down below the filler neck the sensor should start detecting the drop in fluid as you're driving you might still have too much in there?

Thanks for the help . I'll give it a go .

Don't waste your time mate trying to pump it out.


If your remaining range doesn't reset itself after another descent drive you need to reset the system manually via BASIC SETTINGS procedures(level reset & lock reset).
Both are very simple and can be done using VCDS or OBD11.

Cheers guys . Bought obd eleven this afternoon, so fingers crossed

 

[Howzat]

Let us know how this goes because I didn't realise we could reset with OBD11.

 

[Shreknomore]

Update: so obd 11 arrived. Got to the scr reset option but says unavailable anyone have any ideas if not anyone in the Cardiff area with vcds who needs some beer tokens

 

[mmi]

so obd 11 arrived.

Please check the actual AdBlue level and remaining range estimates BOTH in engine and dash display. See below

was driving more then 30min

Hmm... ECU tells the engine has been running only 5 minutes?

IDE00078

Time since engine start

305

The reason to disable the stop/start is because ECU seems to clear some status counters/bits when ignition is cycled.

Anyways, the ECU is seeing AdBlue level correctly and also counting remaining range accordingly. However, the Instruments has another opinion. But that was already known.

Thanks for the reply. Is that with vcds or obd 11 ? I'll have a look again tomorrow.

 

[Robert]

Ah, for that, either works, mate.
They're pretty much on par for most things you'll want to do.

I had this issue after I topped my ad blue up last week. It was the old 650 miles to non start message. It didn't reset so after reading a few threads I added diesel up to more than 2/3rds full, took it for a 8 mile run and it reset.

@Gordon Bennett. Maybe I’m being even thicker than usual but do you mean that you added adblue (ie. not diesel) to more than 2/3rds full? If so how much adblue did you actually put in please?

 

[Gordon Bennett]

@Ayjay lol, sorry I didn’t make myself very clear! I topped the Adblue up (with Adblue) then I topped the diesel up (with diesel) to 2/3rds full

 

[Ayjay]

@Gordon Bennett. So do you believe that putting more fuel in has an effect on the adblue readings? That's a genuine question from a mechanically illiterate numpty!

 

[Shreknomore]

So had another look through obd today. The only things I could find regarding mmi's post are in attached pictures.

Strange - the labeling in OBDeleven is exactly the same as in VCDS (as in the post).

Nope, not a jot, but I read a couple of forums, put some more fuel in as suggested and it worked (after driving around for days with the countdown getting lower and lower). It literally took less than 5 minutes to reset after I filled up with fuel and drove about 3 miles....
