00 Danger Of Poisoning If Oil Is Ingested/Absorbed Through The Skin

Danger of poisoning!

Ingesting oil or absorbing through the skin may cause poisoning!

Possible symptoms are

1. Headaches
2. Dizziness
3. Stomach aches
4. Vomiting
5. Diarrhoea
6. Cramps/fits
7. Unconsciousness

Protective measures/rules of conduct

1. Pour oil only into appropriately marked containers
2. Do not pour oil into drinking vessels (drinks bottles, glasses, cups or mugs)
3. Observe country-specific safety regulations

First aid measures

1. Do not induce vomiting. If the person affected is still conscious, he/she must rinse out their mouth with water, drink plenty of water and consult a doctor immediately. If the person affected is unconscious, do not administer anything by mouth, place the person in the recovery position and seek immediate medical attention.

00 Risk Of Injury If Oil Comes Into Contact With Eyes And Skin

Danger of injury!

Contact with eyes or skin may result in injury!

Possible symptoms are

1. Impaired sight
2. Irritation of the eyes
3. Reddening of the skin
4. Rough and cracked skin

Protective measures/rules of conduct

1. Wear protective goggles
2. Wear oil-resistant protective gloves
3. Observe country-specific safety regulations

First aid measures

1. Eye contact: Rinse eyes immediately with plenty of water for at least 15 minutes; if available, use an eye-rinsing bottle. If irritation of the eyes persists, consult a doctor.
2. Skin contact: Wash off with soap and water immediately. If irritation persists, consult a doctor. NOTE: Do not use solvents/thinners.

00 Safety Instructions For Handling Oil

Recycling

Observe country-specific waste-disposal regulations.

Measures if oil is unintentionally released

1. Personal precautionary measures: Danger of slipping! Keep non-involved persons away from the work area. Wear personal protective clothing/equipment.
2. Environmental protection measures: Prevent oil from draining into drain channels, sewerage systems, pits, cellars, water and the ground.
3. Limiting spread: Use oil blocks to prevent the surface spread of oil.
4. Cleaning procedure: Bind and dispose of escaped oil with nonflammable absorbents. NOTE: Do not flush oil away with water or aqueous cleaning agents.

11 00... Service - engine oil (S85)

Note. On the S85 engine, an oil sump for engine oil is installed with separate oil chambers. At an engine oil service solely the oil quantity from the main oil sump (rear oil chamber) is drained. The engine oil from the front oil chamber is continuously delivered to the main oil sump by a separate oil pump. For this reason, it is necessary to operate the engine for at least one minute at idle speed directly before an engine oil service.

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

1. Remove underbody protection. See «51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION (M5)»(/bmw/m5/e60e61-2004-2010/remont/door-locks-anti-theft-systems/#body-equipment-repair__51-47-490-removing-and-installing) or «51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION (M6)»(ref-263486-S32577391072007090700000) .
2. M5: Loosen service flaps. See «51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION»(/bmw/m5/e60e61-2004-2010/remont/door-locks-anti-theft-systems/#body-equipment-repair__51-47-490-removing-and-installing) .
3. M6: Loosen engine guard.

S85 engine with screw plug (up to 03/07).

Explanation of the instrument display

1. Engine oil level OK.
2. Engine oil level at maximum.
3. Engine oil level too high (= 0.5 litres ovefilled).
4. Engine oil level at maximum.
5. Quick measurement is running: engine oil level is being measured.
6. No value can be currently measured (engine oil temperature = 70 °C).

Scheme 84

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.

Scheme 85

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.

Scheme 86

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.

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.

1. Engine oil level (+ 0.6 liter).
2. Range for maximum.
3. 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

Note. On overfilled level value up to 0.5 litres can be displayed on the instrument cluster. A further overfilling of more than 0.5 litres can only be read out using the diagnosis system. The diagnosis system can display an overfill of up to 3.5 litres. When overfilling is suspected, we recommend correction of the oil filling by using the diagnosis system.

On the diagnosis system select the following steps

1. Complete vehicle
2. Powertrain
3. Engine electronics
