Removing Steering Pressure Line

Information 

• The plug-in lines (plug-in couplings) for the steering and clutch hydraulics have been changed. Modified plug-in coupling system used as of model year 2009. 
• As of model year 2009, the plug-in couplings are no longer loosened by screwing them apart. 
• From model year 2009 onwards, the lines must be pulled apart after releasing the plug connection. Use the loosening tool 9780 to release the connection. 

For more detailed information on the new plug-in couplings -arrows-, see  → 4X00IN PLUG-IN COUPLINGS FOR HYDRAULIC LINES - as of model year 2009.

1. Loosen the pressure line (thinner line) at the connection point (plug-in coupling) -arrow-  in the rear sill area on the left.

   1. 1.1. Loosen the pressure line (thinner line) - up to model year 2008 

      Remove circlip -D-  from the pressure line (thinner line) -2-  . Loosen (unscrew) the plug-in coupling. When loosening, turn at the threaded joint -A-  and counter at the hexagon on the plug-in coupling -B-  .

      Collect hydraulic fluid in a container.

   2. 1.2. Loosen the pressure line (thinner line) - as of model year 2009 

      Release the plug-in coupling using the loosening tool 9780. 

      To do this, fit the special tool on the loosening sleeve plate -3-  and insert it as far as it will go over the 60° chamfer.

      If the tool is turned 180° before fitting, it cannot be inserted.

      The 60° chamfer on the loosening tool must be facing the 60° chamfer from the connector (line -1-  )!

      Once you have released the plug-in coupling (by inserting the loosening tool), pull the lines apart -arrows-  .

      Collect hydraulic fluid in a container. Close off lines with suitable stoppers (e.g. from new lines) to prevent damage in the sealing area. Alternatively, cover the plug-in couplings using a clean, lint-free cloth.

2. Loosen pressure and return lines at the steering gear. To do this, loosen the hexagon socket head bolt -arrow-  and remove the retainer plate (with the front wheels turned in as required). Close off lines or use a collecting container.
