Hello together, at the moment my stand heater no longer starts (Phaeton year 2007, V8). When it was colder the last weeks, it jumped on, but often went off after a few minutes. I thought it might be due to the battery. Now I wanted to try it again because the battery should have recovered. Now the stand heater is no longer working at all. Neither over the AC menu nor over the remote control (but it is still green). However, I can select the residual heat function. Battery voltage when ignition is active, the speedometer shows about 13. That was already less. Are the 13 still too little to start without a motor? Are the temperatures just so that the stand heater, when the engine is on, does not start, because meaningless? Would like to be informed before it goes to the workshop. Must be covered by the perfectCarPlus guarantee anyway, as I see. Best regards Johannes
