My washer jets were shooting black sticky stuff and getting stuck too, and there was a pizza dough yeasty smell from the filler neck.

I put some chlorine in to kill the algae but there was no getting around the solid bits inside clogging the pump filter so I had no choice but to take everything out. I was going to try someone's suggestion of suctioning out the bottom gunk, but when I saw the bottle it was full of algae all along the walls so it would have caused problems again eventually. So I took the whole bottle out, and bathed it in a chlorine solution, scraping any stubborn algae stuck to the inside walls by manipulating a soft wire hook through the opening

The information in this thread made removal quite straightforward, it just took awhile because I was being careful.

Here are a couple of extra tips:
  • The thing that gave me the most trouble actually was the side marker. I have a 1M and there is no spring to push against like some of the other cars. It turns out it is just held in by clips, so just squeeze and pull straight out, starting from the rear first. I have included a picture of the clips for those who need it.
  • To get the headlamp washers to work, turn on the ignition fully, turn on the lights and the first time you pull the washer stalk it will spray the headlamps (but only the first time until you power down again)

In my case I think the washer fluid was just plain water, but I hardly ever use the washer so it must have been festering for awhile. All these years owning cars and I have never encountered this problem before! Now I know I need use up the fluid every now and then and top up with some additives that will kill algae!

Anyway, thanks again everyone!

I am glad it worked out for you, thank you for passing on your tips as it wil help others.

I have had my 135i for 12 years, so far mine has only clogged up once but it is likely to happen again, I was the same with my previous car that I owned for 9 years and this one I never used the water bottle to clean the windscreen either as it makes the car dirty

I do clean the windscreen with the wipers every time I get in the car now though so it may prevent it happening again, I only drive about a 1000 miles a year so a lot of the time the car is not being used
