Hello together, have here again a short question about my SLK. The FZ has installed an electric auxiliary pump which has in the meantime blessed the time (I noticed during the diagnosis, otherwise no effects can be detected). As far as I can see, the pump is exclusively for the residual heat usage with switched off engine to heat the interior with switched on ignition and activated “rest button” at the climate control. umpee also any further sense/tasks? Reason for the question is, I do not use the FZ in winter anyway, so I need the pump, if it is really only used for reheating actually not. Thanks in advance
