Once you removed the gunk, did you put any cleaner through it?My M3 (E92) struggled with this hugely, and it was a massive PITA. I'd have to take the front-wheel and wheel lining off to be able to get access to the gunked up part of the tank. I used to use BMW fluid too and still had to clean it repeatedly.
Charged me about a ton the first time, but I was watching what they did and it's not too tricky.
Strange that it kept getting gunked up
