Adblue Consumption when towing

[watto64]

Since we have had the XC90B5D in july the only time the adblue level drops significantly is when towing, we have covered just over 4500miles of which 2000 is probably towing. Today the 1600mile warning came on and it took 8 litres to top back up..does this seem normal?

It's going to work harder towing and produce more antigreeniegens so its likely that's all it is, generally a tank of the wee is gone in around 6-7k under normal conditions. hth.
