Removing and installing control unit and hydraulic unit - Vehicles with left-hand drive
Special tools and workshop equipment required
t  Brake pedal load e.g. -V.A.G 1869/2-
Removing:
Fitting location:
The control unit is bolted to the hydraulic unit and is located on the right of the engine compartment (left-hand drive).
  WARNING
The brake lines around the hydraulic unit must not be bent!
–  Read out and note the actual control unit coding.
–  Disconnect battery → Electrical System; Rep. gr.27.
–  Remove engine cover.
For vehicles with 1.8 ltr. engine:
–  Remove top charge air hose → petrol engine; Rep. gr.21.
For vehicles with diesel engine and diesel particle filter:
–  Remove diesel particle filter → Engine; Rep. gr.26.
Continued for all vehicles:
   
–  Release the in the -direction of arrow 1- and pull it off the control unit in the -direction of arrow 2-.
–  Position brake pedal load e.g. -V.A.G 1869/2-.
–  Attach the bleeder hose of the bleeding bottle onto the vent valves of the front left and rear left brake caliper and open the bleeder valves.
–  Press down brake pedal with brake pedal load e.g. -V.A.G 1869/2- at least 60 mm.
–  Close front left and rear left bleeder valves.
–  Do not remove brake pedal load, e.g. -V.A.G 1869/2-.
–  Place sufficient non-fluffing cloths under the control unit and the hydraulic unit.
Make sure that no brake fluid gets onto the contacts.

–  Mark both brake lines from the master brake cylinder -A- and -B- and unscrew from the hydraulic unit.
–  Close the brake lines and threaded holes immediately with plugs from the repair kit -1H0 698 311 A-.
–  Mark the brake lines (for brake caliper) -1- to -4-, unscrew and close.
–  Pull hydraulic unit with control unit upwards and out of the shock absorbers.
–  Unscrew the bracket for the ABS control unit from the ABS control unit.
  WARNING
The ABS control unit -J104- and the ABS hydraulic unit -N55- must not be separated from each other.
The hydraulic pump and the ABS hydraulic unit -N55- must not be separated from each other.
Installing:
  Note
t  Only then remove plugs from the new hydraulic unit when the relevant brake line is installed.
t  If the plugs were already removed from the hydraulic unit before the brake line is installed, then brake fluid may escape and adequate filling and bleeding can no longer be guaranteed.
Screw the bracket for the ABS control unit onto the ABS control unit and tighten to the recommended tightening torque.
Moisten the bolt of the support with lubricant, e.g. -D 007 000 A2-, before inserting into the rubber bearings.
Insert the ABS hydraulic unit with bracket into the rubber bearings of the console.
  WARNING
Make sure that the rubber bearings are not pressed out of the console when installing the bracket. After installing, check the ABS control unit for tight fit, otherwise failure may be caused by a malfunctioning.

–  Connect the plug to the control unit against the -direction of arrow 2- and lock.
–  Remove the plugs consecutively from the brake lines and the ABS control unit.
–  Screw the marked brake lines onto the ABS control unit.
For vehicles with 1.8 ltr. engine:
–  Install top charge air hose → petrol engine; Rep. gr.21.
For vehicles with diesel engine and diesel particle filter DPF:
–  Install charge air hose to the side → diesel engine; Rep. gr.21.
–  Install front exhaust pipe with diesel particle filter → Diesel engine; Rep. gr.26.
Continued for all vehicles:
–  Install battery → Electrical System; Rep. gr.27.
  Note
If the battery earth strap is disconnected and connected, carry out certain additional operations → Electrical System; Rep. gr.27.
–  Position engine cover.
–  Remove brake pedal load e.g. -V.A.G 1869/2-.
–  Bleeding brake system → Chapter.
–  Code the control unit -J104- → Vehicle diagnostic tester.
While doing so, a basic setting of the steering angle sender -G85-, the lateral acceleration sender -G200-, the brake pressure sender 1 -G201- and the longitudinal acceleration sender -G251- must be performed → Vehicle diagnostic tester.
