Just to update, it's been since Feb. 5th and we still haven't smelled the 'burning smell". the car was supposed to go in yesterday for a complete PTU replacement. I called and cancelled the appointment. They will sit on the part for one week then send it back as they don't want a $1,500 unit in inventory. I'm bringing the car in to them on Thursday though for a free oil change and Dean, the Ser. Mgr. said they would check to see how much if any the seal is leaking. They will be taking digital pics of the chrome clad wheels that are chipping/pitting. My luck the PTU will leak worse than it appears to now. Still no answer in sight what Ford is doing for the fix, this is what Dean has told me up until yesterday. They just said replace entire unit.
