Is this classified as a dead thread? Apologies if so.
I discovered fuse 203 was pulled on my 2019 M550, found out while troubleshooting the emergency calling malfunction. Thanks to this thread, I installed a new fuse and cleared the codes associated with pulling the fuse. I’m using bimmerlink to open the flaps which remained open after a quick drive. Engine off then back on and I was fairly certain the flaps stayed open. When do they return to auto with bimmerlink? Is it after removing the Bluetooth OBD interface? I’ll try a few more tests, I left the OBD link installed for the time being. Getting annoyed with this… the fuse was pulled and the flaps were closed which makes me wonder how long the previous owner romped on it with flaps closed. I doubt anyone would’ve pulled the fuse when running aftermarket exhaust. I’m hoping the fuse was missed when reverting to stock pipes for sale of the vehicle. Otherwise, the previous owner tried the open flaps/pull fuse mod and hosed it up nicely.
