P38A Rear washer jet pipe 'lost' !

Hi.

Have been an idiot and need some advice please. I removed the rear washer jet to unblock it and left a good inch or two of pipe hanging through the hole, no problem I thought. But when I went back the pipe had recessed back into the metal panel although I could just about see it. In trying to get the thing back through I have made things even worse and now can't see or find the thing. The only access I can see is through the washer jet hole which is nigh impossible. Is there anyway of finding the pipe again and getting back through the hole that anyone knows of?

Thanks

Take the plastic filter and wiper motor cover off, only a few screws and it should be there, probably clean or change the foam filter at the same time.
