Blocked rear washer - BMW 1 series
Discussion
airline and blow it backwards is what i do if some welding wire wont shift it, blow it the way it came from the small trap into the larger pipe and out if you don't have the use of a compressor pop to the fuel station and use thiers (and pay 50p for it ) failing that i boil the kettle and fill the washer tank form empty then give that a go, hot water often shifts stubborn lumps of cr@p that build up in the lines.
Stick some thin wire down the end of it. see what comes out on the end.
Have you confirmed its the rear washer and not the hose coming off the washer bottle? I know in my car the washers weren't working at it was because a rubber valve that selected where the washer fluid was sent had swollen and became stuck.
Try run the rear washer with the motor detached and see if anything comes out the end.

What is that component - just an elbow, or some sort of one way valve? If it's a valve, it'll probably only flow one way and poking is liable to ruin it.
That was my worry.Turns out it is, just needs a suprising amount of pressure to get in moving - certainly can't blow it through manually.
All the grit and crud is now removed and it's working as should.
Reckon the secondary muck in the metal tube was also stopping flow. All back together and blasting out fluid like a good 'un.
Cheers all, saved a few quid at the garage there!
