Changed to approved tyre sizes ?
 
Are the wheels balanced on your winter tyres?

There is a Yaw sensor on the steering wheel shaft, if the wheels are out of balance and you get steering wheel wobble the yaw sensor provides a fluctuating input signal and this triggers the ABS/PSM warning lights.

The fault will clear itself on a restart when a clean signal is sent from the Yaw sensor.
 
thanks for your reply.will try at the weekend.
cheers paul. took the boxster for a drive,this weekend, the warning lights did clear
themselves. so thanks again,,
cheers paul
