Left hand side wing mirror dip on reversing

Good afternoon.

I have recently swapped keys and successfully set my memory seat and wing mirrors to my settings, number 1.

I seem to have lost the handy nearside wing mirror dip whilst reversing, I have searched here but none of the answers seem to work.

It also used to revert to normal position when I turned the ignition off.

I have mk2 Superb Elegance 2.0 tsi.

I use the feature a lot due to using passing places up here.

Any advice welcome.
