11 00... Service - engine oil (S85)
- Perform engine oil service only when engine is at normal operating temperature (>70 °C engine oil temperature).
- An exact engine oil level is only determined with the engine oil temperature = 70 °C.
- The engine oil temperature can be read out on the instrument cluster.
- Observe the exact engine oil filling capacity.
- Overfilling the engine with engine oil will result in engine damage.
- Inspection and drip-off times must be observed.
Risk of damage! For this reason the alternator must be covered with suitable materials.
Recycling: Catch and dispose of drained engine oil in a suitable collecting vessel. Observe country-specific waste disposal regulations.
Necessary preliminary tasks:
- Remove underbody protection. See 51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION (M5) or 51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION (M6) .
- M5: Loosen service flaps. See 51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION .
- M6: Loosen engine guard.
S85 engine with screw plug (up to 03/07).
Explanation of the instrument display:
- Engine oil level OK.
- Engine oil level at maximum.
- Engine oil level too high (= 0.5 litres ovefilled).
- Engine oil level at maximum.
- Quick measurement is running: engine oil level is being measured.
- No value can be currently measured (engine oil temperature = 70 °C).
Run engine at idle speed. Repeatedly press on-board computer button on turn indicator lever until the display for the engine oil level can be read off on the instrument display. Press the on-board computer button for longer than three seconds: displayed value is reset
Run the engine at idle speed until the engine oil level has been remeasured (engine oil temperature = 70 °C). The required engine oil temperature for an engine oil service has therefore been reached. Measuring range from minimum (3) to maximum (2) = 1 liter.
Release screw plug (1) on oil filter cover (2). Tightening torque 11 42 2AZ. See 11 42 OIL FILTER AND PIPES .
Installation note: Replace sealing ring.
Release oil filter cap (2). Tightening torque 11 42 1AZ. See 11 42 OIL FILTER AND PIPES .
Installation note: Renew oil filter element and all sealing rings.
Carry out work on the vehicle only when wearing oil- and heat-resistant protective gloves incl. forearm protection, face guard and protective apron.
Loosen screw plug (1) with nut and a long extension (2). Tightening torque 11 13 1AZ. See 11 13 OIL PAN .
Installation note: Replace sealing ring.
Tilt long extension (1) with nut and screw plug in direction of arrow. Catch and dispose of drained engine oil in a suitable collecting vessel.
Pour in engine oil.
Park vehicle on a horizontal surface. Start engine and run at idle speed until engine oil temperature = 70 °C. Press the on-board computer button for longer than three seconds: Remeasure the engine oil level.
Measuring range from minimum (3) to maximum (2) = 1 liter.
- Engine oil level (+ 0.6 liter).
- Range for maximum.
- Range for minimum.
The filled quantity of engine oil is 0.6 litres above the permissible minimum. Top-up quantity to be calculated: 1 liter - 0.6 liter (display) = 0.4 litres top-up quantity.
Run engine at operating temperature for one minute at idle speed.
Pre-delivery check / engine replacement Carry out distance reset by only using the diagnosis system.
Service - engine oil Distance RESET can only be carried out using the diagnosis system or instrument cluster. Precise measurement of the filled quantity of engine oil can be read out from the diagnosis system, in the DME in the test module (oil level measurement). Top up engine oil, if necessary.
Engine oil overfilled
Start engine and run at idle speed (engine oil temperature = 70 °C). Run engine at idle speed. Repeatedly press on-board computer button on turn indicator lever until the display for the engine oil level can be read off on the instrument display. Press the on-board computer button for longer than three seconds: displayed value is reset
Run the engine at idle speed until the engine oil level has been remeasured (engine oil temperature = 70 °C). The required engine oil temperature for an engine oil service has therefore been reached
On the diagnosis system select the following steps:
- Complete vehicle
- Powertrain
- Engine electronics
- Oil supply
- Oil condition sensor
Switch off engine and loosen engine guard. Release screw plug (1) on oil filter cover (2). Tightening torque 11 42 2AZ. See 11 42 OIL FILTER AND PIPES .
Reassemble the vehicle.
