I just purchased my first Z4 sight unseen. I sent a friend to test it and he said the roof worked normally when he tried it.
However, upon receiving it the roof works completely wacky, almost backwards:
This is similar/same to a previous post, but with no solution: https://z4-forum.com/forum/viewtopic.php?t=115626
1. Upon pressing the open button, the latches disengage, but it gets stuck and makes a buzzing noise.
2. To continue opening, one must spam the open and close buttons to open it. AND keep the CLOSE button pressed to open.
3. Upon fully opening, the buzzing noise continues.
4. To reopen, the buttons must be spammed a few times and the latches disengage. AND keep the open button pressed to close.
5. To relatch, one must switch from pressing open to close. AND press the roof forward to engage as it doesn’t go forward enough and line up.
Opening: https://youtu.be/YYcbANRgK6s
Closing: https://youtu.be/7k6BulRmSPo
Operation with scanner connected: https://youtu.be/U36Be1jjbmY
It throws two codes from the roof module: 43 and 44, both reading Drive, cowl panel, open circuit.
Would anyone have any advice on how I can start diagnosing?
I was attempting to follow this thread but its almost impossible without pictures. https://www.zpost.com/forums/showthread.php?t=925098
If there’s any more info needed, or videos/pics that could help let me know!
Thanks to everyone in advance!
