Checking the Steering System For Leaks (Visual Check)

Checking the steering system for leaks (visual check)
With engine idling, turn steering wheel as far as the stop and hold still. The maximum possible line pressure results in this way.

In this position, check all pipe connections for leaks and retighten if necessary.

Perform the check for a maximum of ten seconds. A longer check should always be interrupted by a brief pause after approximately ten seconds

Checking Pentosin CHF 11 S hydraulic fluid in the power-steering system





The reservoir is located in the engine compartment. There are two marks on the dipstick located on the reservoir cap. One side bears the mark "Cold" for a cold engine (approximately 20 C) and the other "Hot" for a hot engine (approximately 80 C).

Check the fluid level (Pentosin CHF 11 S) with the engine stationary and cold (approximately 20 C).
1. Open engine compartment lid. Open reservoir cap.
2. Wipe dipstick. Close reservoir cap and open it again. The fluid level should lie in the hatched area beneath the "Cold" mark (mark = maximum level at 20 C). Top up with Pentosin if necessary.* The upper "Hot" mark is intended for a fluid temperature of 80 C.

In no case add too much Pentosin!* The respective marks are for the maximum fluid level at the "COLD" or "HOT" temperature.

Notes
If assembly work was performed previously, check the fluid level with the engine idling and without operating the steering.*

Multiple steering operations (maneuvering) with the engine switched off change the fluid level in the reservoir - the fluid level rises. In this case, the engine must be run for at least 5 seconds before the fluid level is checked.*
