How do I check the oil level on my 996?

Display and measurement of the engine oil level

/!\ Caution!

• Risk of engine damage.
  
• Regularly check the oil level.
  
• Do not allow the oil level to fall below the minimum mark.

Conditions for measuring the oil level
1. Vehicle is level.
2. Engine is off.
3. Ignition on.

Oil return time

Before the oil level is measured, the engine oil has to have flowed back into the oil pan. The time taken for the engine oil to flow back depends on the engine temperature and how long the engine has been stopped. This waiting time is counted down in the onboard computer display when the ignition is switched on. The oil level display segments start to “cycle”.

It is best to measure the engine oil level with the engine at operating temperature. Correct measurements and short waiting times are achieved in this way.

Initiating oil level measurement

1. Switch the ignition on (do not start the engine).
   The engine-oil level measurement display appears in the onboard computer.
2. Allow waiting time to elapse.
   Once the measurement has been completed, you can read off the engine oil level on the segment display. If the oil level has fallen below the minimum mark, the segment below the minimum mark flashes.
3. The difference between the min. and max. marks on the segment display is approx. 1.25 litres. One segment of the display corresponds to a quantity of approximately 0.2 litre.
4. Add engine oil if necessary. Before adding oil, switch the ignition off. Never add more engine oil than required to reach the max. mark.

Oil level measurement during refuelling

The oil level is automatically measured during refuelling. If the oil level is too low, “Check oil level” appears in the on-board computer display. However, this measurement is performed only if the following preconditions are met:

The engine is at operating temperature, the ignition is off, and refuelling is completed within 15 minutes.

Failure
A failure of the oil level display is indicated by a warning message in the on-board computer.
