On the motorway it was choosing to cruise in 6th gear.

Also it is very jerky when changing down a gear.

Need to get it to the dealers for them to check, but has anybody else had this problem?

Tried to do the transmission relearn by holding the accelerator down with just the ignition on, but not sure it actually does anything.
Hi,

I've driven almost 13000 kms with my MPPSK and can report no issues. I feel sorry for you and hope it gets resolved well.

A couple of venues for you to explore before the dealer sorts you out:
  1. Change the Sport Individual menu to put transmission in comfort. Select that and see whether the shifting pattern changes
  2. Plug in an OBD adapter and check for any errors using BimmerCode, BimmerLink or similar. Does it report anything? Errors should be easily visible.

Do let us know how this issue gets resolved!
