Removal

Caution
The rate-of-turn sensor is a micro-mechanical component and is very sensitive to impacts!

Information
^ Perform removal and installation with the ignition switched off!

1. Move the front seats into the rear seat position.





2. Remove side-panel lining in front of the center console on the left -A- and right.





3. Remove fastening nuts of the rate-of-turn sensor on the right -arrow- and left.
4. Pull out the rate-of-turn sensor and unlock and pull off the connector with the ignition switched off.

Information

Installation

1. Install in reverse order.





2. After installing the rate-of-turn sensor, read out the PSM fault memory with the Porsche System Tester 2 and erase. Carry out a static test. Then start the engine. The PSM-related lights in the instrument cluster must go out when the engine is running. Read out the PSM fault memory again. There must not be any stored faults.
