There is no snap test. I just had my smog done last week on my BHW with no issues. Do you have any Propel synthetic diesel stations near you? You can try to run two tanks of that first and then do the smog test again. I do that with my Golf since it's highly modded and it reduces the black smoke quite a bit.

I didn't think so. Maybe the tester was doing his own thing. If so the OP needs to be raising ell, getting a refund and complaining to the ARB.

My AHU should be coming up again in a few months so I guess I'll find out. My Dodge too if I decide to start driving it again.

Take it to another inspection station. Most just check for no check engine lights.

If you mean CAT was removed (and not actual mufflers), that is a whole other issues, as many inspection stations look for CAT as a proxy for seeing if any emissions items have been removed. A lot of diesel trucks went straight pipe years back (before CA ramped up inspections on them) and shops have been instructed to inspect exhaust system for mods.

We used to have emissions testing here in British Columbia. Because of the way the system works, I didn't have to take my car in until it was six years old.

Well, upon my first visit to the inspection station, I noticed that my vehicle registration documents had the fuel type listed as "Gasoline!"

I pointed this out to the inspector, and he was able to change the fuel type to diesel in the vehicle registration system.

Had I not brought it to their attention, I guess they would have been testing my vehicle using whatever procedure they use for a gasoline engine car. Maybe it would have failed?

Do your registration documents in California mention anything about fuel type? Make sure it's correct!

Dirty air filter reducing engine's ability to breathe?

As a few said before use biodiesel. I put a bottle of crisco in the UK and it worked. I had failed the day before.

Where exactly is the TDI's UK located?
Please don't do this. A tank or two of biodiesel can't hurt, though.

? United Kingdom. You don't need a tank, just some to dilute.

The point is the OP, who's disappeared, got ripped off based on dlai's recent experience.

If he just goes to another tester he's out money. Also, the original clown may have put some notes in the system about it failing which could cause him problems.

Missing mufflers are probably grounds for a fail but that's not what got him.

I guess I aimed too high with that one.
