Prius 2003 running good nct & tax- please read

Selling Toyota Prius 2003. Bought this one a few months ago for practice. NCT valid until December 2026. Tax valid until February 2027. The car now displays a red triangle due to a loss of connection between the ECU and the hybrid battery (P3030 code). Maybe good for someone who knows about the car. The car still runs and drives normally. Please add 200 for tax to get the final price for this car (paid 400 for the road tax). If you need any information, please contact me. Thanks for reading.
