The speed sensor is the engine rpm sensor. It tracks how fast the engine is turning over and sends this info to the computer. If it is defective, your car will stall or run rough not even start It is a common issue on Audi.

Sporadic faults with the engine speed sensor are not uncommon and will usually set a fault code , though the check engine light may not illuminate. They are also suspect when all else fails with intermittent no starts/stalling issues. Your torque converter may be an issue if your transmission fluid level is low since insufficient fluid will allow the lock up clutch in the torque converter to apply when braking to a stop , stalling the engine.
