Hello together, I hope again (at least for myself) new phenomenon discovered: Since March 2009 I drive a V8 (year of construction 2004, model year 2005) among other things with stationary heating. After the temperatures were already too pleasant in the spring, I come only now into the embarrassment to take the stationary heating by means of remote control into operation. And there is also the problem: The remote control works in principle, i.e. I can set the stationary heating in motion and also switch off again, BUT the optical feedbacks of the remote control (see below) described in the logbook on pages 3.1.2. 24 u. 25 remain out. Specifically, when pressing the ON button the LED briefly green, when pressing the OFF button briefly red, whether I stand near the car or at the other end of the city. More does not work there, the batteries in the hand transmitter I have already replaced the nice two times, but unfortunately without changing the described behavior… 🙁 According to the manual the feedbacks should look like this: Display => Meaning Light green = Heating was not switched on the stand # Did not receive the signal?
