WARNING: This page is about a different car, the 2014 Porsche Cayenne, 2013 Porsche Cayenne, 2012 Porsche Cayenne, and 2011 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
- After installation is complete, raise the vehicle so that the wheels are no longer touching the ground.
- Open the engine cover and reservoir.
- Fill the reservoir up to the MAX marking until the level no longer drops.
Engine is not started!
- Turn the steering fully to the left and right and hold it at full lock for approx. 30 seconds on each side until the level no longer drops.
Continually check the fluid level and fill to the MAX marking again.
- Lower the vehicle onto its wheels.
- The next procedure causes the fluid level in the reservoir to fall rapidly, so constantly add Pentosin CHF 202 (2nd mechanic required!).
The reservoir must not be sucked dry.
- Start the engine and leave it running for approx. 1 second. Top up continually with Pentosin.
Repeat the procedure several times until the fluid level no longer drops.
- If the fluid level in the reservoir does not fall any further when the engine is briefly turned over, start the engine and leave it running at idle speed.
- Turn the steering on full lock several times to the left and right at idle speed and hold it at full lock for max. 1 second. Observe the fluid level (a second mechanic is required). Continually add fluid until the level in the reservoir remains constant and no more air bubbles circulate in the reservoir when the steering wheel is turned.
- Switch engine off and set the correct fluid level. This must be between the MIN and MAX markings.
