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.

Components / Pipes

IMPORTANTMaintain the highest possible standards of cleanliness around the pipe connections when dismantling and assembling components/pipes. Even the tiniest dirt particles on the pipe connections or damage to the pipes can result in leaks in the air spring system! Do not kink, twist or crush lines.

Pipe connections must be sealed off with adhesive tape immediately after they have been removed. The adhesive tape may only be removed shortly before the connection is reinstalled.

Air spring strut / air spring

Note. If a vehicle has been driven with a depressurized air spring strut/air spring, the air spring strut/air spring must always be replaced.

Check air spring strut/air spring for damage. See 37 00 ... Checking Air Springs For Damage

37 00 ... Checking Air Springs For Damage

37 10 001 Initial Operation With Test Run of Dynamic Drive

Note. The Service function Initial operation of Dynamic Drive must be carried out after: Work on the Dynamic Drive system which involved opening hydraulic lines Replacement / Programming / Coding Dynamic Drive control unit Replacement lateral acceleration sensor Parameters and zero point of new sensors have been learned

Bleeding power steering

IMPORTANTAdhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system. Using contaminated equipment to add fluid may introduce dirt particles into the fluid reservoir and significantly reduce the service life of the power steering system. Do not use any filler funnels or similar! Use only Pentosin CHF11S from original containers! The fill level may only be checked or adjusted when the engine is stopped! The fluid temperature should be approx. 20°C here. Ensure that the cap is fully screwed in prior to the fill level check.

Note. To avoid mix-ups when filling with hydraulic fluid, mark the fluid reservoirs or their caps with identification marks.

CHF Pentosin CHF11S

Scheme 10

Scheme 10
  1. Thoroughly clean fluid reservoir and its immediate surroundings
  2. Check and correct fill level NOTE: The fill level can come to rest above the "MAX" mark when the engine is at normal operating temperature. This is dictated by the design in that the marking on the dipstick is referred to a fluid temperature of 20°C. With the engine at normal operating temperature (approx. 50-60°C fluid temperature) adjust a fill height 15 mm above the "MAX" mark. Do not under any circumstances draw off the fluid to the "MAX" mark when the engine is at normal operating temperature. Hydraulic fluid: BMW Service Operating Fluids
  3. Start engine
  4. Turn steering wheel left and right twice in each case up to full lock; if necessary, top up hydraulic fluid (e.g. if hydraulic system is completely drained)
  5. Move steering wheel to straight-ahead position and turn off engine
  6. Check and correct fill level with engine stopped
  7. Check hydraulic system for leaks

Performing initial operation with test run

Note. Hydraulic fluid temperature must be between 50°C and 70°C (vehicle at normal operating temperature)

Bleeding power steering

IMPORTANTAdhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system. Using contaminated equipment to add fluid may introduce dirt particles into the fluid reservoir and significantly reduce the service life of the power steering system. Do not use any filler funnels or similar! Use only Pentosin CHF11S from original containers! The fill level may only be checked or adjusted when the engine is stopped! The fluid temperature should be approx. 20°C here. Ensure that the cap is fully screwed in prior to the fill level check.

Note. To avoid mix-ups when filling with hydraulic fluid, mark the fluid reservoirs or their caps with identification marks.

CHF Pentosin CHF11S

  1. Thoroughly clean fluid reservoir and its immediate surroundings
  2. Check and correct fill level NOTE: The fill level can come to rest above the "MAX" mark when the engine is at normal operating temperature. This is dictated by the design in that the marking on the dipstick is referred to a fluid temperature of 20°C. With the engine at normal operating temperature (approx. 50-60°C fluid temperature) adjust a fill height 15 mm above the "MAX" mark. Do not under any circumstances draw off the fluid to the "MAX" mark when the engine is at normal operating temperature.
  3. Start engine
  4. Turn steering wheel left and right twice in each case up to full lock; if necessary, top up hydraulic fluid (e.g. if hydraulic system is completely drained)
  5. Move steering wheel to straight-ahead position and turn off engine
  6. Check and correct fill level with engine stopped
  7. Check hydraulic system for leaks

Performing initial operation with test run

Note. Hydraulic fluid temperature must be between 50°C and 70°C (vehicle at normal operating temperature)
