My wife had an 05 1.6 TDCI Titanium a while back. Her alternator packed up on the way home one night, so she was driving with lights etc. on the battery from start up. She got about 3 miles before it gave up the ghost. Then with jump starts she managed half mile relays.

RAC told me at the time there were a lot of these faults on this mark 2 model along with Mondeos which highlighted a generic problem with their alternators. The car was only just out of the 3 year warranty, and Ford paid half the cost of the alternator. Just 20K on the clock.
