Wasn't your VW built before emissions control became standard? Meaning it is a non-legislative vehicle (no emissions control systems on board). I'm not sure when emissions control became standard, in the U.S. I think it was 1966, but other parts of the world did not immediately follow suit.

We also have a non-legislative vehicle (1946) and non-appearance na lang sa emissions testing because even with everything set to factory specs, the chances of failing are still high. This is because there were really no set emissions standards during the time of the engine's manufacture.

Same case din with the vehicles of other members of the Vintage Car Club. I don't attend the meetings much but I think they are planning to take steps to exempt pre-emissions control/historic/vintage vehicles from emissions testing.
