AUTOMATIC TRANSMISSION FLUID TYPE
Note. Automatic Transmission Fluid (ATF) was developed especially for automatic transmissions. It requires additives which are carefully matched with each other, a high viscosity index and a solidification point below -40°F (-40°C). Friction behavior of ATF in plate-type clutches under very different operating conditions is extremely important. Other important factors are: Wear protection Oil film shear resistance Adhesive property Oxidation resistance Corrosion inhibition Sludge prevention Temperature-dependent viscosity changes Compatibility with sealing materials
AUTOMATIC TRANSMISSION FLUID LEVEL CHECK
Note. Checking fluid level may be necessary if there is evidence of a leak, a complaint related to fluid level, or repairs made to transmission.
Service Interval Indication
Service interval indicator consists either of colored LED blocks or actual mileage remaining until next service. (Scheme 1) Service indicator (which displays OIL SERVICE, INSPECTION I or INSPECTION II) can be reset using the reset tool (models with under-hood diagnostic connector such as Z3 and 7-Series) or instrument cluster odometer button (models without under-hood diagnostic connector such as 3-series and 5-series). See SERVICE INTERVAL LIGHT RESET.
Service Interval Light Reset (Using Reset Tool)
An under-hood engine diagnostic connector is necessary to perform reset procedure with reset tool. (Scheme 2) To reset the service indicator following an oil service or inspection, insert the reset tool into the under-hood BMW diagnostic connector. (Scheme 3) Follow instructions supplied with tool. When procedure is complete, release button and remove tool. If an error is made before the above sequence of events is completed, repeat the procedure.
Reset service light by performing the following
- Ignition key must be in OFF position.
- Press and hold trip odometer reset button in the instrument cluster (left button), and turn ignition key to first position.
- Keep the button pressed for approximately 5 seconds until one of the following words appear in the display: "OIL SERVICE", or "INSPECTION", with "Reset".
- Release reset button and press it again until " reset" begins to flash in the display. (Scheme 4)and (Scheme 5).
Service due is shown with "reset" if coded minimum consumption limit has been reached and resetting is possible. If "reset" is not shown, minimum limit has not been reached and resetting is not possible.
- While "reset" is flashing, press left button briefly to reset service interval. After display has shown new interval, following will appear: "END SIA".
System can only be reset again after 2.5 gallons of fuel have been consumed.
