Sorry for the delayed answer. It is a closed system threfore no fluid change is necessary. Just remember, roof may have leaks and when they do, water accumulates in the lowest area of the truck where the top motor is. So check for leaks, check where the motor is for water, check if the is rust accumulating on the motor best of all, clean all the roof drains so the water can drain to the ground.

Birçok kişiye yardımcı olmaya çalıştım. Hepsinin duruş pozisyonu farklıydı. Benimki kapalıyken bozuldu. Hangi pozisyonda olursa olsun process aynı.

@@turkbektas7664 Cabuk cevab icin teskler, dün soğuk havada problemsiz acildi, ama kapatırken yarıda takıldı. Bütün gece boyunca garajda kaldı, lakin hep ayni problemi gösteriyor Function failure roof actuation, tabi herkezin ayrı acısı vardır.. ama sizce pompasimi iflas etdi?

I thought I covered pretty much everything in summary. I didn’t want a long video to bore people to death. It worked beautifully upon replacement. Did you have questions?

Turk Bektas hi there, I appreciate posting it on. I’m about to do mine on 2014 428i. Pretty much the same mechanism. Do you have to bleed the lines? Because I thought just like brake lines need bleeding I was wondering this may need bleeding. I will appreciate your thoughts on this. Thank you Moe

@@khorag3193 no don't bleed the lines. in fact none of this is necessary. I just replaced the electric motor. very easy. only 3 screws! i replaced it with a reconditioned motor. leave all the hydraulics and lines in place and just replace the motor. change the fluid first. good luck

Khosraw Ragheb well thanks to this comment.. you might have saved my bank lol. Could you please contact me directly? I want to let you know what my top is doing, maybe you can tell me what the issue is?

@@juliancamano4424 hello Julian. I'm not a technician but, I replaced the motor only, because water had got in the electric motor. Everything else in the assembly are new and in good shape. The car has only 9000 miles. Please tell me what your car is doing I might could guess something.

I have a 335i hardtop convertible and the top will not come down. I’m getting a red roof symbol on my dash. Any idea what it could be?

Khosraw Ragheb sorry I just saw this! If you can call or text me I can give you my number in direct message. My top will unlock but then will not go down so I am thinking it is the motor that lifts the top. But I have no clue which motor that is or how to remove it to rebuild haha. Please help! Have not opened my top in almost half a year!

Justice Webb check the fuses, and the two relays, see if the electric motor plug is tightly connected.
