N54 vs N55 Cats

Can anyone confirm that the N54 had the "secondary" cats and the N55 did not? Just had the smog station refuse to test my car as it was missing the secondary cats. He kept pointing at the WU-TUC on the emissions label as his proof that they should be there.

It's a march 2010 car.

Have you done any mods to the exhaust? Put your VIN into realoem.com and look up the factory exhaust configuration to know for sure.

Realoem certainly does not show any secondaries for N55 LCI cars, N54 does have them.

Thank you both, I should have thought to look there.

And no, there have been no modifications since I've owned the car. Not a great day, skipped out to get that taken care of and got the big FU from the test guy.

I'll take it to another place tomorrow. What a waste of time.
