I wouldn’t assume it was full to begin with, it’s like getting a full tank of fuel without asking!

I hear what you are saying (and i'm the least trusting person of dealerships !), but the last thing i want to do is start pouring in fresh Adblue only to find i max it out, overfill / spill.

Yes you can over fill the AdBlue, and actually later cars have quite substantially increased consumption as well.

So personally I would leave it alone until you get the low DEF message and then you should be fine to dump a 10L bottle in.

Then you'll know if the tank was full or not as either your range figure will be much higher or you will simply be back to where you started,

Hi,
I recently had my engine light come on, it usually comes on but quickly goes out, after a week of it staying on I decided to call Land Rover assist, The mechanic how came out was excellent whilst he connected his gadgets to my car checking all the fault history and clearing 3 fault messages he informed me that my car needed engine, transmission and gear selector software updates installing, he installed all the latest software and still the engine light was on, I happened to mention I topped up the adblue tank a couple of weeks ago. He electronically checked the level of adblue and told me I'd overfilled it, he then proceeded to drain the tank by 3ltrs and the engine light went out.
There is no warning for overfilling or any mention in the handbook re: overfilling, so the tank is 16ltrs but the max you should put in is 14.5 ltrs, as there is no way of knowing how much is in the tank he told me to wait ubtil the car tells me it's low then put no more than 10ltrs in, the car tells you it's low when it's down to 3.5 - 4ltrs so 10 Ltrs is about right.
Excellent mechanic.
Hope this info helps.

Hi I think I may have over filled as I have this message. Any idea how it was drained and the location of the adblue tank?

Many thanks.

Yes, this is the standard advice, often repeated on the forum. If you have a later car you can monitor the DEF (AdBlue) situation via "vehicle info" (which is only available with ignition on, engine off).

It’s at the rear of the car, alongside the fuel tank. There’s a plug in the bottom for draining the fluid out, there’s a post on here with further details if you search.

Hi Guys

Just a quick note that the Dosing error was due to a clogged DEF injector. This caused the NOx sensor to go out of limits. Remove and clean the sensor with water. I'll try and attach photos.

A small point of note. When the DEF counter gets this low:

10 litres exactly of Adblu will register as 4850 miles to empty. This is for vehicles 17MY> that have had the PCM update that reduced the consumption range from 10k to circa 5k miles. Given that all these vehicles will have been to a dealers at least once by now, this should mean all of them have had this applied, so the above figures compute.

Thanks for the pics. I knew this was a simple job, but wasn't sure exactly where to find the injector. LR Rescue man who did mine said it's sometimes so bad he has to use a phillips screwdriver to get the gunge out. He also said he'd seen this a lot less often on more recent cars.
