Nice explanatory video but considering all the faffing about with screwing the bottle on in addition to the drips, wouldn't it be far easier placing your basic find-everywhere funnel into the filler neck and pour directly into that in the same way as we used to fill up with petrol having run out lol. My vehicle doesn't use AdBlue so of course I am speaking without any direct knowledge and basing the above only on the fact that the AdBlue doesn't need to be topped up every five minutes.
