Hello to all … I’m new here and imagine myself shortly before . 50 years young from Munich and some BMW VERÜCKT. To my prop where I’m a little unsure , my KGE hose is kaput ,I ordered immediately new from the bay . When I expanded then I saw that the old has a 2 pole connection ? The new but not … what a function does the connection have and can I install the new hose without connecting, am somewhat unsure . As for electrical am I don’t know if there is any error or a function..would be happy to answer. BMW 740i F01 Bj 2010 Best greetings
