Thanks steve I assume that is the connection next to the tank. And I bet the tank isnt cheap if I need to replace the tank

Hi guys. My EML came on today randomly. i have ran VCDS on it and have got the following code and i am just want to make sure that what i have worked out is correct and to find out what is the next/best way to proceed with this - as in DIY fox or if its better to go into a garage? the data is as follows: 1 Fault Found: 16932 - Control Circuit for Reductant Heating 1 P20BC 00 [172] - Short to Plus MIL ON - Intermittent - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 5 Mileage: 113115 km Date: 2021.12.31 Time: 18:40:02 Engine RPM: 866.50 /min Normed load value: 53.7 % Vehicle speed: 0 km/h Coolant temperature: 38 °C Intake air temperature: 36 °C Ambient air pressure: 1000 mbar Voltage terminal 30: 14.100 V Unlearning counter according OBD: 40 Reducing agent quality sensor: urea concentration: 399.99 % Sensor 2 for temp. reducing agent: act. value: 11.0 °C Sensor for reducing agent fill level: voltage: 13107.0 mV Reducing agent metering system heating circuit 1: actual current: 0.0 A Reducing agent metering system heating circuit 2: actual current: 0.0 A Pump for reducing agent: speed: 0.0 /min Mean temperature of SCR catalyst: 58.9 °C Readiness: 1 1 0 0 0 (i can provide full scan details if required) from what i have found it sounds like my adblue heater No. 1 has failed. the help im needing with is: 1. would i be correct in saying that this is inside the tank, if so do i need to remove tank etc to change it? 2. has any one got any help or advice in doing this DIY style? thanks in advance.
