Since my van is over 5 years old now I need to get is smogged every two years here in CA. Two years ago was the first time I had to take it in and it did not go well. That story is here:
This year I expected everything to go smoothly since I really had not driven the van much in the time since I last took it in due to family issues preventing us from travelling. On this inspection though they checked the aftermarket fuel tank & basically said it was illegal due to the CARB sticker only being valid on model years up to 2011. My van is a 2013 model. So Sportsmobile handed over the van with an invalid CARB sticker on the gas tank.
The inspector did not fail me but told me to go out & see if I could get additional info that would make me legal. I contacted Transfer Flow and they were very quick to email me the correct CARB # to give the smog station and mailed me out a new sticker when I inquired if that was an option. I went back today and got the van passed with no issues.
So if anyone has a model 2012 or 2013 van and is registered in CA you may run into this problem. My sticker has D-288-105 which only goes through 2011 model years. The updated CARB # you will need is D-288-129. You can get a copy of that here. It is a good idea to have that on hand just in case.
