Had a chat with my dealer today and learned a few things about Adblue. Adblue levels are monitored by a sonic sensor which determines the level of Adblue in the tank by reading the surface level from above. MY17 cars are prone to warnings if the tank is even a little overfilled which can result in an engine shut off - engine will not start as Adblue is too low (= cannot be measured by an oversensitive sensor) MY16 are not so sensitive.
The second issue is that poor quality Adblue warnings have been occurring due to a software fault. Nonetheless, when buying Adblue it is important that it complies with the relevant standard.
You mean this one?

Have I got some updates for this thread
Okay, so first thing, I'm onto my third tank of AdBlue... and I'm getting about 7500KM/fill (4660 miles). Which I'm not very happy about.
So, a couple of weeks after the last fill, my amber transmission warning light comes on...
Pull over, check manual... says its an emissions control problem, but safe to drive... so drive a few more days while I wait to see LR on Monday. Next thing the light is replaced with the above warning... "No Engine Restarts In 870km. Diesel Exhaust Fluid Dosing Malfunction".
Awesome.
At first they gave me the third degree on what type of AdBlue I used (the AdBlue type that Shell sells for filling up cars...)
And then they informed me that the Corporate Service Plan *now* includes AdBlue top ups. Good. Because they insisted it didn't last time. I expect this will make people a lot happier, since they like to charge about $250 a fill, where as Shell charges... $23.
Anyway, at first they thought it was a loose pin on the sensor... so fixed that, reset, etc...
They kept it for two days, having to do extensive on road testing or something like that.
2 hours after picking the car up, it happened again.
So back to the dealer.
This time they diagnose an issue with the ECM, or PCU. And its going to take 4-6 weeks to get a replacement. And since the countdown has started... I can't really use the car for 4-6 weeks.
So, Land Rover supplied a Discovery 5
( the Disco 5 drives well, but the 180 TD4 engine in the super base spec is very underpowered, fine in a DS though. Air suspension was neat. I prefer the steering wheel)
...
Anyway, fast forward a week later, and my dealer calls me to tell me they received updated instructions from JLR. Reset the PCU 3 times and update the software with a new build they received over night... and apparently that's fixed it. Well... we'll see.
They mentioned the original PCU had gotten corrupted.
So, a SW issue? Exacerbated by a loose pin on the sensor? I dunno.
Wonder what my DEF usage is going to be now...
