Low pressure on adblue

[Playdeadrin]

I got a warning that started that the car wouldn’t start after 600 miles. I have A 2015 tdi golf with 46,000 miles on it. They found that a line was leaking so they replaced that. Now they can’t reset the error code. It says my ad blue is at 116%
and won’t clear the warning. Anyone else have this problem and how long did it take to fix?

Generally speaking from my reading here is that if the 600 mile warning is the first you were given that the heater unit itself is bad and should be replaced under the emissions warranty. They replace the whole module not just parts. On mine anyway. What is the code showing?
