Removing:
–  Observe safety precautions when working in the area of high-voltage components → Chapter.
–  Observe the risk classification of the high-voltage system → Electric drive; Rep. gr.00.
Danger to life due to high voltage.Risk of severe or fatal injury due to electric shock.The high-voltage system must be de-energised by a suitably qualified technician.
–  De-energise high-voltage system now → Electric drive; Rep. gr.93.
–  Disconnect battery → Electrical system; Rep. gr.27.
 

Removing and installing brake system pressure accumulator -VX70-, RHD vehicles

–  Disconnect connector -3-.
–  Release hose clip -1- and remove coolant hose.
–  Remove coolant expansion tank from bracket. To do this, release catch -2- with a thin screwdriver.
 

Removing and installing brake system pressure accumulator -VX70-, RHD vehicles

–  Unscrew nut -2- and remove bracket -1-.
–  Move coolant hoses and electrical wiring away from the area of the brake system pressure accumulator -VX70-.
–  Draw off as much brake fluid as possible from brake fluid reservoir using brake filling and bleeding equipment -VAS 5234-.
 

Removing and installing brake system pressure accumulator -VX70-, RHD vehicles

–  Place sufficient lint-free cloths in the area of the brake system pressure accumulator -VX70--1-.
–  Unscrew brake lines -2- from brake system pressure accumulator -VX70--1-.
–  To do this, unscrew union nuts -3-.
–  Seal threaded hole immediately using sealing plugs -1H0 698 311 A- or sealing plugs -5Q0 698 311-.
–  Fit dust caps from the brake caliper bleeder valves onto brake lines.
–  Release and pull off connector -4-.
 

Removing and installing brake system pressure accumulator -VX70-, RHD vehicles

–  Pull brake system pressure accumulator -VX70--1- together with bracket -3- and rubber dampers -2- upwards off bracket.
Installing:
Install in reverse order. Note the following points:
 

Removing and installing brake system pressure accumulator -VX70-, RHD vehicles

–  Ensure rubber dampers are seated correctly in bracket of brake system pressure accumulator -VX70-.
–  Ensure that retaining pins have been fully and evenly inserted into rubber dampers.
–  Ensure secure seating by pulling.
Ensure that rubber dampers of retainer are not pressed out of bracket when installing. After installation, check that the brake system pressure accumulator -VX70- is securely seated, otherwise malfunction can occur.
–  Bleed brake system → Chapter.
–  Subsequently bleeding the brake system → Chapter.
–  Perform basic setting for electromechanical brake servo → Vehicle diagnostic tester.
