c220d auto Sports mode switching on

Hi I have an 09 C220i d auto with paddles tiptronic gears

I have factory fitted sports mode

for some reason the sports mode is now switching on by itself, it wont switch off now unless i stop car and switch ignition off but comes back on again soon after I start driving again.

Have I touched something on paddles ? to allow it to go into sports mode automatic or anthing else that anyone can think off ?

Thanks
