MODELS 203 up to 30.6.02, 208 as of 1.8.99, 210 as of 1.7.99, 215, 220 with CODE (494a) USA version
Figure 1
The fuel tank content (this function is not integrated in model 203; only the estimated range is displayed) and the estimated range are displayed on a common display screen on the multifunction display (A1p13).
Tank content, function
The tank contents are displayed in US gallons (picture 1) or in liters (picture 2).
It can also be displayed in UK gallons. This is done by using the Star Diagnosis tool to code the appropriate national variant.
Figure 2
The trip computer of the instrument cluster (A1) needs the following information to determine the tank contents:
- The fill level in the fuel tank:
In model 203, the fuel gauge sensors for the left and right halves of the tank (B4/1 and B4/2) are polled by the rear SAM control unit with fuse and relay module (N10/2) and the appropriate message is transmitted over the interior CAN.
The instrument cluster (A1) receives this message, assesses it and displays the corresponding fuel level.
In models 208 and 210, the fuel gauge sensor (B4/1, B4/2 or B4) is polled directly by the instrument cluster (A1).
In models 215 and 220, the fuel gauge sensor B4 is polled by the rear SAM control unit (N10/8) and the appropriate message is transmitted over the interior CAN.
The instrument cluster (A1) receives this message, evaluates it and displays the corresponding value as the tank content.
The tank contents are displayed in steps of 1 l or 0.2 gallons. No coding is necessary for the type of fuel tank (normal tank or ski bag). This is taken care of by the different designs of fuel gauge sensor.
Range, function (except 203)
The estimated range is displayed in miles (Figure 1) or in kilometers (Figure 2).
The range is calculated by taking the quotient of the fuel tank content and the average fuel consumption ("SINCE START").
The following information is therefore required to calculate the range:
- The current fuel tank content (see above)
- The average fuel consumption, using the data from the short- distance memory ("SINCE START")
The range is displayed in increments of one kilometer or one mile.1 1 The range is updated more frequently when the fuel level in the tank is in the reserve range. The reserve range used as a basis for this may differ slightly from the reserve range of the fuel level and reserve gauge (A1p2) of the instrument cluster (A1).
