Removing and installing parts of the ESP system The description of the structure and function of the ESP can be found in self-study programme No. 28. t  Remove and install yaw rate sender -G202- and lateral acceleration sender -G200- → Chapter t  Remove and install steering angle sender -G85- → Chapter Special tools and workshop equipment required t  Vehicle system tester -V.A.G 1552- t  Diagnostic cable -V.A.G 1551/3- or -V.A.G 1551/3A- Remove and install yaw rate sender -G202- and lateral acceleration sender -G200- The removal and installation procedure of the yaw rate sender -G202- and the lateral acceleration sender -G200- is the same except for the direct replacement of the sender to be removed.   Note t  Before disconnecting the battery determine the code of radio sets fitted with anti-theft coding. t  After connecting the battery, perform the following: –  on vehicles with radio encoding, carry out the coding, –  set clock, –  initialise power windows on vehicles fitted with power windows → BookletOctavia Removing –  Disconnect battery.

–  Remove the bottom part of the dash panel -1- → Body Work; Rep. gr.70. –  Remove the bottom part of the steering column trim panel -2- → Body Work; Rep. gr.70.

The yaw rate sender (-G202-) -1- and the lateral acceleration sender (-G200-) -2- are fixed with a common bracket -3- at the mounting bracket for the steering column -a-.   Note Due to the common bracket, the senders cannot be removed separately. After removing the bracket, the yaw rate sender -G202- and the lateral acceleration sender -G200- can be replaced separately. –  Disconnect the plugs -arrows- from the yaw rate sender -G202- and from the lateral acceleration sender -G200-. –  Unscrew screw -5- and remove bracket -3- with yaw rate sender -G202- and lateral acceleration sender -G200-. Replace yaw rate sender -G202-

–  Unscrew the nuts -a- from the yaw rate sender (-G202-) -1-. –  Remove the yaw rate sender (-G202-) -1- from the bracket -3-. -2- Lateral acceleration sender -G200- –  Insert the new yaw rate sender (-G202-) -1- into the bracket -3- and align it straight. –  Screw on nuts -a- and tighten. Replace lateral acceleration sender -G200-

–  Lever off the holder -2- from the lateral acceleration sender (-G200-) -1- using a screwdriver. –  Remove the lateral acceleration sender (-G200-) -1- from the bracket -4-. -3- Yaw rate sender -G202-

–  Insert the new lateral acceleration sender (-G200-) -1- into the bracket -3-. -4- Yaw rate sender -G202-   Note The inclined side -arrow- of the lateral acceleration sender (-G200-) -1- must point in the direction of the holder -2-. –  Push the holder -2- over the lateral acceleration sender (-G200-) -1- and lock. Install

–  Mount the bracket -3- with the lateral acceleration sender (-G200-) -2- and the yaw rate sender (-G202-) -1- on the mounting bracket -4- for the steering column -a-. –  Insert and tighten screw -5-. –  Fit on plug for yaw rate sender (-G202-) -1- and plug for lateral acceleration sender (-G200-) -2- (arrows). –  Install the bottom part of the steering column trim panel → Body Work; Rep. gr.70. –  Install bottom part of dash panel → Body Work; Rep. gr.70. –  Connect battery → Electrical System; Rep. gr.27. –  Initiate basic setting → Chapter. –  Interrogate the fault memory → Chapter. –  Erasing fault memory → Chapter.

Removing and installing steering angle sender -G85- Special tools and workshop equipment required t  Vehicle system tester -V.A.G 1552- t  Diagnostic cable -V.A.G 1551/3- or -V.A.G 1551/3A-   Note t  Before disconnecting the battery determine the code of radio sets fitted with anti-theft coding. t  After connecting the battery, perform the following: –  on vehicles with radio encoding, carry out the coding, –  set clock, –  initialise power windows on vehicles fitted with power windows → BookletOctavia. Removing –  Disconnect battery. –  Put the front wheels in straight ahead position. –  Remove steering wheel → Body Work; Rep. gr.69.

–  Unscrew screws -1-, -2-, -3- and -4-. –  Remove the handle for the steering wheel adjuster as well as the top and bottom part of the steering column trim panel. - Check whether the front wheels are in the straight-ahead position. –  If necessary, fit on the steering wheel and put the front wheels in a straight ahead position. –  Remove steering wheel.

The steering angle sender -G85- is fitted together with the coil spring -2- in the housing -1-.   Note The following two work steps must only be performed when reinstalling at a later stage the same housing with a coil spring.

–  Position the steering angle sender in the centre position: A yellow dot must be visible in the window -1-. The markings -arrows- must be flush. Make sure this position is maintained.

–  Secure the coil spring -2- against unintentional turning by covering it with adhesive tape -1-. -3- Housing

Disconnect plugs -1- and -2-

–  Carefully release catch hooks -arrows- and remove housing -1- with steering angle sender -G85- and coil spring. Install –  Slide housing -1- with steering angle sender -G85- and coil spring onto the steering column and lock into position with steering column switch -arrows-. –  Connect both plug connections.   Note After removing the transport protection or the adhesive tape do not turn the coil spring, only the positioning of the steering angle sender -G85- in centre position is allowed. –  Removing transport protection or adhesive tape.

–  Position the steering angle sender in the centre position: A yellow dot must be visible in the window -1-. Markings -arrows- must be flush with each other. Make sure this correct position is maintained. –  Remove the top and bottom part of the steering column trim panel as well as the handle for the steering wheel adjuster. –  Install steering wheel → Body work; Rep. gr.69. –  Connect battery → Electrical System; Rep. gr.27. –  Perform the basic setting of the steering angle sender -G85- → Chapter. –  Interrogate the fault memory → Chapter. –  Erasing fault memory → Chapter.
