On my 2016 car if I send the 0x46 frame once, after the last 0x4e frame, 
the car wakes up and then goes back to sleep without enabling climate 
control. I adjusted things to send it a couple of seconds after the 0x4e 
frame and this made it work. Climate control came on and then turned off 
again after about 15 minutes (I removed the old code so this was the car 
switching itself off).

Do you happen to have a capture of everything on the bus with timestamps 
for the whole remote climate control start up sequence?

I'm guessing that the TCU is waiting for something from the car before 
switching to the next step. I suspect this is the same with locking, the 
ovms is blindly sending the remote command message a fixed number of 
times and the lock message causes my car to try to lock multiple times.

Nice, the existing code to support new and old will work on this too.
