Adblue Fault Message

[Scott123]

Hi, I've got an Audi A4 2.0tdi, 2015. The Adblue Error fault message has appeared, I've connected it up and theres no error messages coming up.

Any ideas on what to try next before going to Audi.

Also, the fault states no start within 300 miles, I know theres 15 litres of Adblue in there, will the car still drive after the 300miles if I cant get it looked at before the 300 miles runs out?

Thanks

I suspect there's an issue with the tank float which may have not stuck of failed sensor. Audi will probably drain the tank and reset the system first

Hi if you have access to VCDS you can do a reset on the tank level and see if that cures it, also on the advanced measuring values you can check the realtime current volume of the tank also where did you come by the 15 litre figure as when the refill light comes on they only recommend a 10 litre top up which is about right as I refilled mine today with 10 litres and the realtime level was 100%, think you might have overfilled the car that will definitely make it throw a wobbly.
