Hi guys .
I had this happen from leaving a air freshner tucked in the netting in the p footwell it was touching the plast on the console .
It bubbled up like this almost like it was a skin on the plastic .
I moved the freshner and just left it as i didnt want to pop the bubbles , a few months on and its not very noticeable almost like it has dryed up .
Not much help but i make sure to not get anything on the plastic .
Greg .
