Functions/components for national version
:
- CHECK ENGINE indicator lamp (A1e26)
- Fuel system open warning (fuel tank cap indicator)
- Purging system with leak test.
In addition components:
- Tank pressure sensor (B4/3)
- Activated charcoal canister shutoff valve (Y58/4)
- Vent line to activated charcoal canister without vent valve and with large diameter, model 171.
- During refueling the fuel vapors are collected at the filler neck and passed to the activated charcoal filter (ORVR = Onboard Refueling Vapor Recovery).
- The activated charcoal canister is enlarged.
- The pulse switchover valve is designed for a larger flow volume (color coding).
- As of MY 2005, a PremAir sensor (B11/15) may be installed at the radiator on model 211. It has the task of recognizing a coated PremAir radiator. This catalytically converts ozone into oxygen and therefore needs controlling. The engine control unit recognizes the PremAir sensor via a local interconnect network interface and checks the plausibility of the detected temperature pattern.
If a PremAir radiator is replaced by an uncoated radiator then an error is detected and the "CHECK ENGINE" indicator lamp actuated.
- Flexible-fuel vehicle (FFV), engine 272.920/940 as standard as of 1.6.06
FFV-vehicles can be fueled with premium fuel or with Ethanol (portion of Ethanol 85 %). This creates mixtures in the fuel tank with an ethanol concentration of 0 to 85%. The proportion of ethanol is taught in at every filling of the tank and the mixture formation is adjusted accordingly.
