When do you fill your adblue tank?

[yesman]

Hi all, pretty much as the title says when do people fill their cars adblue tank when the warning comes on? On mine the 1500 miles warning has come on and I know the tank is 13 litres, I ordered a 10 litre adblue but not sure if there will be the room left in the tank for 10 litres or if I need to run it down a bit to make space. Cheers

If you are fed up of the warning put some in now from the 10 litres, like 6 litres and then sometime later put in the 4 litres.

The display will tell you how much can be added. It will give the minimum and maximum volumes. I add the full 10 litres just after the warning comes on and it takes it all easily

Spot on, Cheers, that's what I was hoping as Ive got a 10litre bottle coming this week, Not sure if this is correct but I have heard that you can't store an opened adblue bottle as it can go off so wanted to use the full bottle in one go! Cheers again👍

There is also a procedure in the handbook to allow the adblue level sensor to update after you re-fill. You need to turn the ignition on for ~30 seconds without starting the engine. The display normally updates and resets after about 10 - 15 seconds then on mine. After that, start engine and carry on as normal.

 

I certainly wouldn’t store an open bottle of adblue. It horrible stuff and goes crystalline. It certainly has a limited shelf life. I buy the VAG branded stuff from a dealer & keep all the receipts. I know it’s more expensive than using a forecourt pump, but if there are any future problems with the adblue system, then they can’t use the "contaminated adblue" excuses. Adblue system repairs are VERY expensive!

You can store AdBlue safely in a sealed container out of the way of children or idiots for a period of time, 

after all it is stored in the cars AdBlue tank possibly for a year or 3 in some cars doing low annual mileages and i have never heard of anyone draining the AdBlue tank and refreshing during a cars time spent on Dealers forecourts or Lock downs. 

There will be plenty new cars with Adblue in that left the factory sometime late last year or early this year.

 

Sitting parked outside, summer and winter, hot and cold temps, while someone buying 20 litres of AdBlue and decanting 10 into the car and storing 10 litres might well have it in sealed / airtight container in a shed / garage.

Well adblue came today, order it before I read bigmicks reply, also changed the adblue tank level measurements from gallons to litres, car said it needed 10.5 litres to refill tank so it took the 10 litres I'd bought easily, my only issue was it took 4 times of turning the ignition on, without starting the engine, before it would reset, left it for over a minute each time, started to panic a bit as only had the car for a week and then it reset to 7000miles range!! Anyone had this issue before?

I personally use the AdBlue pump at the gas station.
- No issue of potential AdBlue left in the bottle.

- Easy to refill

- Quicker than bottles

- Half the price per liter compared to bottles.

I´ve definitely forgotten bottles. 😁

Mine  (MY17) doesn't need the "turn it off and on" routine to recognise it has been refilled. I just start and go - within a few seconds the warning goes away and the new adblue range is displayed.

Really, is that what you just do anyway or does your manual state something different? Which engine does your car have?

190 TDI. I think it was on here someone said cycling the ignition wasn't necessary to  reset the range. There were quite a few threads on adblue here when I got mine and I asked about it since I had never had adblue previously. From memory (it was a couple of years ago now) when I did my first refill, within a few seconds it had reset by itself so I didn't need to turn it off again.

 

It's been the same with each refill - it resets almost immediately with no need to cycle the ignition. FYI I have kessy and wait to select my profile before starting the car, so that delay may be why it had reset and didn't need cycling. Just guessing though.
