I've got an urS4 on my lift right now which had a metal rectangular  
shaped "something" come loose of the flywheel. I say "something"  
because there is some debate as to if it is purely a ballance weight,  
or if it is what the TDC sensor uses to generate it's signal. It is  
very clear that it used to be welded to the flywheel, no clue how it  
came off. Any way arround it when the "something" came off of the  
flywheel it damaged one of the referance sensors and in the end wedged  
between the starter and the ring gear, seizing the engine.

Bottom line: If theres no signal from the sensor make sure whatever  
pickup is still there. It seems that a somewhat scary number of people  
have experianced failure of the pickup.
