Filling and bleeding the power steering system
Filling and bleeding the power steering system
Special tools and workshop equipment required
t  Vehicle diagnosis, measurement and information system -VAS-
t  Catch pan (commercially available)
t  Extraction bottle (commercially available)
t  Jumper cable (commercially available)
t  Hydraulic oil → Chapter
  Note
t  Hydraulic oil amount in the system: approx. 0.80 ltr.
t  The screwed lid for filling the power steering system with hydraulic oil is located in a recess on the frame side rail in the left section of the engine compartment.
t  Because of the different dimensions of the battery the screw cap of the hydraulic oil reservoir on certain vehicle versions is concealed by the battery tray and battery. If this is the case remove the air filter, the battery and the battery tray.
t  Only fill up an empty hydraulic system when engine is cold.
t  Hydraulic oil → Chapter
t  Hydraulic oil amount in the system: approx. 0.80 ltr.
t  Use new hydraulic oil only.
t  Topping up hydraulic oil → Chapter
t  Check the hydraulic oil level with the dipstick of the screwed lid of the engine pump aggregate reservoir.
t  Do not refer to the „MAX“ and „MIN“ markings on the reservoir to check the hydraulic oil level.
Method:
  Note
t  If necessary remove air filter → Engine; Rep. gr.24 (petrol engines) or → Engine; Rep. gr.23 (diesel engines).
t  Then if necessary, remove battery and battery tray → Electrical System; Rep. gr.27.
   
–  Fill the engine pump aggregate reservoir -2- with hydraulic oil and check the hydraulic oil level with the screwed lid dipstick -1-.
For checking the hydraulic oil level, screw the screwed lid hand-tight to the reservoir.
  Note
  N48-0602
The correct oil level can only be determined for a fully screwed in screwed lid.
–  For an empty power steering system fill with enough hydraulic oil to reach the top marking -arrow B- on the oil dipstick.
   Arrow A - bottom marking on screwed lid
  Caution
Observe the applicable safety instructions for disconnecting the battery with jumper cables!
–  If necessary connect removed battery to jumper cables.
–  If necessary install air filter → Engine; Rep. gr.24 (petrol engines) or → Engine; Rep. gr.23 (diesel engines).
–  Raise the vehicle until the front wheels are fully off the ground.
–  Put the wheels in straight-ahead position.
–  Unscrew the screwed lid of the hydraulic oil reservoir.
–  With the engine off turn the steering wheel 10 x from stop to stop.
–  Check the level of hydraulic oil, if necessary top up with oil → Chapter.
–  Loosely screw on the screwed lid of the hydraulic oil reservoir, do not tighten.
–  Start engine and run for approx. 10 seconds.
–  Switch off engine.
–  Check the level of hydraulic oil, if necessary top up with oil → Chapter.
–  Loosely screw on the screwed lid of the hydraulic oil reservoir, do not tighten.
–  Repeat the following steps until the hydraulic oil level no longer drops. The hydraulic oil level must reach the top marking.
t  Start engine.
t  Turn steering wheel 10 x from stop to stop.
t  Switch off engine.
t  Check the level of hydraulic oil, if necessary top up with oil → Chapter.
–  Screw the screwed lid onto the engine pump aggregate reservoir.
  Note
Any residual air in the steering system will automatically escape while driving for approximately 10 to 20 km.
–  Disconnect the jumper cable.
–  If necessary re-install the air filter.
Only run through the following steps if the battery has been disconnected and the battery, battery tray and air filter have been removed.
  Note
t  If necessary install battery tray and battery → Electrical System; Rep. gr.27.
t  Then if necessary install air filter → Engine; Rep. gr.24 (petrol engines) or → Engine; Rep. gr.23 (diesel engines).
t  Pay attention to the measures after re-connecting the battery → Electrical System; Rep. gr.27.
–  Performing self-diagnosis → Chapter.
If faults are stored in the fault memory:
–  Remove fault.
–  Erase fault memory.
