So I let my Adblue go low (won’t do that again!) down to 350 miles. Mainly because I buy it at the pump that was until one week ago a lot cheaper at £1.06 per litre. You have to find a garage that HGV’s use as they have large Adblue tanks on their vehicles. And of course pumping it tells you exactly how much to add so you don’t overfill. 2.75 gallons added converted into litres by Google.
Initially it didn’t change the mileage. And for over a week it remained low. I tried all the usual hacks driving it. Leaving it 30 seconds, ignition on / off etc. Then all all of a sudden one day it was showing 4400 miles. And everything was back to normal.
Or so I thought……..next thing I am driving along and I get a long beep and Adblue warning for 600 miles to refill. I did 80 miles and it was down to 350 miles.
Spoke with VW assist who advised a VW dealer visit for VW to reset it. And / or VW updating the software.
Went to my local VW van centre who were next to useless. With the service guy saying he had never heard of any issues unless it had been over filled. (So obviously he had heard of Adblue issues!
)
With a 4 hour drive ahead of me. And 350 miles remaining. I just had to hope that I didn’t stall it until I got to my destination.
It errored all the way to a nail biting 150 miles after 50 miles actual driving distance Before it self resolved and showed 5500 miles Adblue remaining.
So hang in there if you experience this Adblue debacle. As several people have reported it should update.
I actually wondered about unclipping the cables from the Adblue tank. Turning the ignition on, so that it would show open circuit to the EMU. And then ignition off. And re-plugging the cable back in. I would have tried that had it not reset itself.
