WM 430501 Checking fluid level (PDCC)

Information

Information on PDCC fluid level

Only Pentosin CHF 202 may be used in the reservoir. Pentosin CHF 202 can be ordered under the following part number: Quantity supplied 1 litre = 000.043.203.33.

A dipstick with a -MAX-MIN marking- is fitted on the reservoir lid (steering hydraulics dipstick shown here). The markings are for a fluid level on a cold engine (approx. 20 °C).

The MAX marking can be easily exceeded at higher fluid temperatures.





Even small leaks can cause the fluid to escape and damage the tandem pump as a result of the high oil pressure in the hydraulic circuit.

A low fluid level, lots of air bubbles and/or any major degree of foam formation in the reservoir indicate a leak in the system. Visually check the system for leaks.

Before filling the reservoir, any existing leaks must be eliminated. In this case, the oil level in the reservoir must be checked when the engine is running and when it is stopped. If the oil level drops to the bottom of the reservoir or if lots of air bubbles rise up, then there is air in the hydraulic system. It is quite normal for a few air bubbles to appear in the reservoir immediately after topping up or following repair work - this is not a fault.

Checking fluid level

CAUTION

Increased risk of accidents and material damage if too much Pentosin CHF 202 is filled in or if Pentosin CHF 202 comes into contact with the coolant hoses when filling or topping up.

- It is possible to overfill the system, causing Pentosin CHF 202 to overflow onto coolant hoses and other components.

-> The engine must be run for approx. 20 seconds prior to checking the fluid level.
-> If coolant hoses come into contact with Pentosin, clean them thoroughly with water IMMEDIATELY.
-> Replace visibly swollen coolant hoses.

Information

To check the exact level of the fluid, the hydraulic oil should have a temperature of approx. 20 °C when the engine is cold.

The reservoir (fluid tank) is located under the cover in the left of the engine compartment -item 6- , at the plenum panel wall (looks identical to the steering fluid tank).





PDCC component arrangement

1. Open the engine compartment lid and remove the left cover. => 700219 Removing and installing front cover (engine compartment)

Information

The fluid level must be almost the same when the engine is running as when it is stopped.

2. Start the engine (check for sufficient ventilation.) and let it run for approx. 1 minute. Check the fluid level while doing so. Then switch off the engine. => 4303AW Safety Requirements for Porsche Dynamic Chassis Control (PDCC)
3. Wipe off the dipstick and check the fluid level again => see figure (steering hydraulics dipstick shown here). Close and then re-open the cap. The fluid level must be in the designated range (MAX/MIN level at approx. 20 °C). Top up with Pentosin if necessary.





4. After completing the tasks, fit the relevant components and close the engine compartment lid.
