Yeah the front bumper lines are symmetrical - all good. They've now said they can adjust the actual headlight washer instead of the bumper (which wasn't an option for me) & failed. So I have two new washer covers & a nozzle being ordered in, thankfully.
Whether this will be a permanent fix or even resolve the issue we will have to find out. I'll be sure to use strong screenwash in the future during winter so I don't cause any problems for the headlight washers again
