Ford transit 2015 2.2RWD Adblue malfunction

[Ryan9153]

Hi guys my transit as soon as turn on Adblue system malfunction comes on only 31 miles until none start. No fault codes are showing in the RCM. However in live data the Reductant tank temperature sensor unit is showing 6.55 volts which is out of range so I believe this may be triggering the adblue mil light. I remember from before when I changed the adblue tank heater this was reading 1.3 odd volts. The adblue tank heater unit I bought from Ford main dealer. Anybody any ways to test the sensor is it part of the adblue heater I just bought or is it somewhere else. Any help appreciated.

When it went on my last van it was in the tank and had to replace the whole unit but I seem to remember that from a post on here saying there is also a second heater unit on the crossmember but changing the tank sorted it..
I had to have mine changed in Ireland when on holiday at a Ford dealership and after it drank add blue I ran it for 3 months before going back to Ireland they had it haft a day but said they found nothing but did reprogram it after that it was back to normal usage.
