Information On Displaying And Measuring The Engine Oil Level

Information: 

In the event of complaints relating to the oil level indicator or the warning messages "Oil level minimum reached" or "Oil level below minimum", please provide the customer with the following information:

• To ensure safe driving and to protect the vehicle from damage due to excessively low oil levels, the oil levels in the system are continually updated and compared with the previous measured values in the electronic control system while driving: Measuring the oil level while driving thus ensures a reliable measurement result. 
• If a warning message appears while driving  due to the fact that the engine oil level is too low, the required amount of oil must be added as described in the Driver's Manual.
• If a warning message indicating that the oil level is too low appears when the vehicle is stopped,  Porsche AG recommends that you check the oil level while driving again in the instrument cluster after driving a distance of at least 50 km (30 miles).  It is important to ensure that the engine is at operating temperature and an engine oil temperature of at least 90°C/194°F is displayed.

This information is summarised again in a Driver's Manual Supplement  . The purpose of the Supplement is to inform the customer of the possibility of an implausible oil level display or warning  , while at the same time providing an effective method of measuring the oil level. In the event of a complaint, please give the Driver's Manual Supplement - "General information on displaying and measuring the engine oil level"  to your customer.

You will find the Driver's Manual Supplement  for the Cayenne S and Cayenne Turbo (92A) as a PDF file in PIWIS > Information media >> TI Technical Information releases >>> Group 1, 1701 - General information on displaying and measuring the engine oil level.

Measuring oil consumption

Information 

The oil consumption must only be measured under the following conditions: 

• Oil consumption  as per customer statement 0.5 l - 0.8 l/1, 000 km (US:  0.53 - 0.84 qt/620 mls); UK:  0.44 qt - 0.7 qt/620 mls) and vehicle mileage  of more than 10, 000 km/6, 200 miles 

or

• Oil consumption  as per customer statement more than 0.8 l/1, 000 km (US:  more than 0.84 qt/620 mls; UK:  more than 0.7 qt/620 mls) - irrespective of vehicle mileage.

Tools and materials: 

Clean oil collection container (capacity of at least 10 litres)

Oil measuring cup

Engine Oil Consumption Measurement Sheet (PIWIS Information System > Standard forms >> "Engine Oil Consumption Measurement Sheet" (PDF file)

Work Procedure: 

To measure engine oil consumption, complete the following steps one after the other: 

• Check engine-oil level (on the instrument cluster and using PIWIS Tester II)
• Create vehicle analysis log (VAL)
• Drain engine oil and measure existing engine oil quantity
• Correct the engine-oil level
• Measure reference oil quantity
• Perform oil consumption test drive over 1, 000 km/620 miles
• Drain engine oil and measure oil quantity
• Determine oil consumption
• Create vehicle analysis log (VAL)

Information 

To document the

• reference oil quantity
• amount of oil added during the test drive
• amount of oil drained after the test drive

and to determine the actual oil consumption  , use the "Engine Oil Consumption Measurement Sheet  " (PIWIS Information System > Standard forms >> "Engine Oil consumption Measurement Sheet" (PDF file)).

Attach the measurement sheet to the related PQIS job.

1. Check engine-oil level. 
   1. 1.1 Check engine-oil level on the multi-function display in the instrument cluster. 

      Dynamic measurement (= an oil level stored while driving is displayed).

      1. 1.1.1 Park the vehicle horizontally and on a level surface. Do not open the engine compartment lid because if you do, the dynamic oil level value will be deleted.
      2. 1.1.2 Switch off engine and ignition.
      3. 1.1.3 Switch on ignition; do not start engine.
      4. 1.1.4 Display the oil level on the multi-function display in the instrument cluster.
      5. 1.1.5 Document the oil level (in segments) in the corresponding field in the => "Engine Oil Consumption Measurement Sheet  ".
   2. 1.2 Check the engine-oil level as described in 

      > 170101 CHECKING ENGINE-OIL LEVEL USING THE PIWIS TESTER 

      using the PIWIS Tester  and document the measured engine-oil level (in mm) in the corresponding field in the => "Engine Oil Consumption Measurement Sheet". 

2. Create vehicle analysis log (VAL)  and attach it to the PQIS job.

   Information 

   When draining the engine oil, the engine and engine oil must have an operating temperature of at least 90°C (194°F). The engine temperature and engine oil temperature can be read out of the DME control unit using the PIWIS Tester (DME control unit > 'Actual values/input signals' menu).

3. Drain engine oil. 
   1. 3.1 Drain engine oil into a clean  container.
   2. 3.2 Remove oil filter; pour any remaining oil into the container.
   3. 3.3 Make sure that the oil pan and oil-filter housing drain completely (allow to drain for 15 minutes  ).
   4. 3.4 Allow oil in the container to cool down to room temperature (approx. 20°C/68°F)  .
   5. 3.5 Measure the exact amount of oil collected using a measuring cup.
   6. 3.6 Enter the amount of oil drained in the corresponding field in the => "Engine Oil Consumption Measurement Sheet  " and evaluate it.

      Determined oil quantity	Evaluation
      less than 8.1 l  (US:  less than 8.5 qt/UK:  less than 7.1 qt) = Oil level minimum reached	MIN warning message plausible
      8.1 l - 9.5 l  (US:  8.5 - 9.9 qt/UK:  7.1 - 8.4 qt) = Oil level OK	MIN warning message implausible
      more than 9.6 l (US:  more than 10.1 qt/UK:  more than 8.5 qt) = Engine is overfilled	MIN warning message implausible

   7. 3.7 Dispose of engine oil and oil filter.
   8. 3.8 Install new oil filter.
4. Correct the engine-oil level. 
   1. 4.1 At room temperature (approx. 20°C/68°F)  , measure the exact amount  of oil to be filled in  - 9.0 l  (US  : 9.5 qt; UK  : 7.9 qt) - and pour it into the engine.
   2. 4.2 Perform a test drive to bring the engine and engine oil  to an operating temperature  of at least 90°C/194°F  .

      The engine temperature and engine oil temperature can be read out of the DME control unit using the PIWIS Tester (DME control unit > 'Actual values/input signals' menu).
