Adblue refill complete but warning light still counting down.

Post by kevinmcf » Sat Oct 13, 2018 1:48 pm

Hi,
I had the usual no restarts in 250miles warning and went and filled the tank with adblue as normal. Following the fill the sensor seemed to be stuck at the 250miles but now has begun to count down as is now at 170miles. Any ideas on how I could resolve this or should I take to the LR garage?

Thanks in advance for any help.

How long ago did you fill? If you've slightly overfilled it can confuse the sensor until the levels have dropped again. I believe it's an ultrasonic sensor that looks for the liquid surface, and it can only "see" so high.

I know the tank is 14 litres, but I've heard it will take as much as 17. I don't know at what level the sensor starts having problems. I always used to just stick in an entire 10 litre bottle from Halfords once the warning light came on.

It sounds like it has either been overfilled or the sonic sensor has failed - it's a known fault. Push the button in the roof panel and get Assist to come and sort it out for you. Take it to a dealer at your peril.

I overfilled mine and the sensor couldn’t read it, iirc we got to around 170 miles to no start and I chickened our, had to take it to dealer to drain the tank reset and refill. Excellent service from Taunton Landrover, did the above and no charge.

Nice to see a dealer that values repeat custom. They are very rare these days....
