Hello Community,
I own an E93 M3 from 2008.
Unfortunately, a vehicle update was carried out due to a defective control unit.
Unfortunately, this also included the CVM control unit.
After subsequent coding, the soft top can no longer be closed by radio key.
I have read that the CVM could be taught this function again via downgrade (ZUSB).
Have any of you ever tried this or have any ideas?
Thanks for tips
