Ad Blue Warning Light - any ideas ???

[Texwade]

Just started a big drive around Europe and topped up Ad Blue before leaving based on dash read out. I don’t think I did the reset on filling.



Once I get to France I get an engine warning light that the adblue level sensor has a problem (I carry a code reader). It’s giving me 1700 miles of range despite being full I’ve added a bit more to see if that pushes the range up a little but it’s locked at 1700.

I only need 1200 miles to get home (1000 at a push as I don’t mind a tow once n UK). I’m trying to get it looked at here in Italy but it’s a bit of a challenge - speaking to an Italian garage tomorrow to see what they suggest. And know people in Germany with a VW garage so may stop there on way home and see if they can sort it out.

Seems like a small broken sensor is causing a load of problems … I’ve got a warranty but no use in Italy.

Any bright ideas other than praying the 1700 is accurate !

Don't top it up.

It's a known issue:
A) Over filling results in level sensor going faulty
B) crystals forming in the ad blue tank / sensor ( requiring new ad blue tank ££££)

Something you can do is siphon off a litre (in addition to the amount you topped up - if possible)
this way you your below the max level.
Then add some Ad Blue cleaner (anti crystal) , some have reported this fixing the issue.
