Gearbox hesitation

[dazzpowder]

I recently had my LCI 535d software updated and ever since I'm getting the dreaded 'hesitation' as I slow down at a junction for example then suddenly accelearate to exit the revs now shoot up to around 1500rpm and nothing until a split second but which actually feels like an eternity later the car just takes off as if finally finding a gear. Anyone have this issue and a resolution? I thought this was a thing of the past with the new 6 Speed ZF box.
