I have a CI Carioca 625 , the electric motor which extends / retracts the steps is broken and i cant find a replacement motor or replacement broken part. Please see photos . There is a sacraficial piece of casing at the back of the motor which has broken off due to the ‘one step controller node ‘ failing . Does anyone know ehere i can go to getba replacement motor , or replace the piece that has broken off at the rear of the motor. Many many thanks, Mike
