Answer:
A
lot of people are wondering the same thing: what year was my engine
built? The simple fact is, in most cases we don't know, for a couple of
reasons.
First, VW liked to use parts in a range of years. Since we're talking engines, Volkswagen made an engine code AH. That engine was made from 1971 to 1974.
Second, VW's demand-prediction abilities were sorely lacking. They'd order 22 million of something, build 20 million cars to put it in, and wind up putting it in next year's models.
And third, your engine has probably been rebuilt three times by now. Is an engine that was originally built in 1971, and that was rebuilt in 1979, 1986 and 1997 still a 1971 engine? I think not, but maybe that's just me.
I can give you year groups for your engine code, and that's as good as you can get without writing Volkswagen. Credit: John Muir's How to Keep Your Volkswagen Alive and sources all over the Internet.
