Hey guys, so back when i had my 335 we all did this and to this day i still dont know why people do this whole "golf tee" stuff... there is a simpler way!!!!!!
for those that dont know, you open your trunk, in the 1 series, you remove the little cover that is found on the drivers side , inside trunk, where the taillight is. opent that up, there is 2 cutouts in the 1 series, my 335 had 1. the second smaller one, closer to the tire is the one you want. its sort of difficult but you have to push out the cushoin thing just a little bit untill you see the valve. there is a little plastic actuator with a metal pin. PUSH IN the pin, and pull up the cap and it will come out.
DONE!
it sends a message straight down! to where you guys are zip tieing and all this other stuff and tells the flapper to remain open. This may throw a internal code into the system, however, i assure you BMW does not care about this. i had my car in and out of service for 2 years, replaced fuel pumps, the works! and never had issues with this.
save yourself the time, and headache of perhaps maybe damaging anything down there physicall by using this method. here is a pic. PM me if you have any questions.
