DTCs may be present in the front seat pneumatics control modules, J873 and J872 (address words 88 and 89) or in the rear seat pneumatics control modules (in certain A8 models only), J875 and J874 (address words 8A and 8D). No leak is present. There is a software issue in the seat pneumatics control modules that causes the seat pneumatics to automatically actuate in high altitudes (change in air pressure) or in fluctuating temperatures in order to maintain pressure.
