• 10142253May 28, 2018Engine cooling. Technical Background The coolant pump for the high voltage battery actively monitors its own speed and current consumption. For a given commanded speed, if the actual pump speed exceeds a defined value and the current consumption drops below a certain threshold, a dry run condition is detected. The pump communicates this to the high voltage battery control unit and fault code P0C4A00 is stored. One possible cause…
• 10142248May 22, 2018Equipment, Engine cooling. There is a possibility that the pressure hose between the charge-air cooler and throttle valve for cylinders 4?6 is rubbing against the cooling fan housing on the affected vehicles. This can cause a leak in the pressure hose at the chafing point over the service life of the vehicle. This will result in reduced engine power and the Check Engine light will be activated.

• 10134865Mar 21, 2018Visibility (wipers, defrost, mirrors). Subject: Wiper arm on rear wiper Situation: There is a possibility that the affected vehicles were fitted with a rear wiper on which there is a crack on the cone of the wiper arm due to amanufacturing error. This can cause the cone to break, thereby breaking the connection between the wiper arm and rear wiper motor and interrupting the power supply required to drive the rear wiper.
• 10134863Mar 19, 2018Electrical system. Subject: Control unit for high-voltage charger Information: Due to a software error, there is a possibility that the control unit for the high-voltage charger will not switch to energy-savingmode after the vehicle is stopped in the event of specific user behavior.

• 10125208Nov 8, 2017Electrical system. Technical Concern: Due to input handling in the VTS software, the Porsche Car Connect initialization fails. The ninth character in the VIN may be an "X" (e.g. WP0AF2A7XHL123456). However, the system sees this "X" character as invalid and does not transmit the installation code to the backend server. In this case, the initialization ends unsuccessfully. Additionally, the PCC portal does not register the failed…
• 10125198Oct 20, 2017Electrical system. Technical Concern: This failure is the result of faulty message monitoring within the instrument cluster. Because the instrument cluster cannot properly detect and display the current cruise control status, the cruise control does not engage. Service Information: The recommended repair is to replace the instrument cluster. Only part numbers with suffix "G" or later should be used.
