there is sensor in distributor called hall sensor ,this generates the pulse for your spark.this is probably faulty.

How are you checking the spark? tough the old plug? Did you check the spark from the coil? If not do this first, be careful it can bite, if the spark is hot aka blue replace the wires and rotor they both have resisters in them that can go bad. If not get an other plug wire any will do does not have to be from a VW. place it into the dis. cap and check it with out a spark plug, if the spark good the wires are bad.
Reminder turning up car can fix most problems.

to be honest with you, stop throwing parts at this car and have it diagnosed properly by a good technician.

The most common reasons for them going out are not using dielectric grease properly when installing, and from washing your engine.

I believe this was a huge issue with Volkswagen vehicles
