I own a 98 E320. The original owner of the car is from Cailfornia. Upon obtaining the orginial invoice from MB there is an accessory code #494 which has a description "Calif Emisson Control Equip".

I was under the impression that the engines on this car (V-6 with dual spark plugs/cylinder) meet the California emissions from the factory. Does anyone know if additional emission control equipment was added?
