The motor is the same as some cars.

Bosch part # 0 130 007 027, available from a good auto electric store under that number. 55-80$ list( I was low), and I got one for 55$. Used in earler 911's as the A/C condenser fan motor, seen discounted on the net to the mid-50's. The Porsche part dies in exactly the same way. According to the ETK, the same fan ass'y is used in all the k's up to the K12, so the same motor ought to work in all of them. I haven't found out yet if they're rebuildable under the Bosch part#, but I will. Also if just the brushes and bushings can be had. I'd be unshocked if VW and/or Audi use a motor from the same series (BPA) for some similar application.
