Hello, I don’t really know what to do now, and I hope someone can give me some good advice here. Vehicle: Mazda 6 GH Diesel Built 2008 My problem: My heating is via my Webasto remote control, but it only comes out cold air, or the vehicle does not get warm. The car was bought by me used, in the invoices of the previous owner I discovered an invoice, where a Webasto Telestart T91 heater was installed. In 2014 the water pump was supplied by the standing heater. Now I was at a Webasto installation operation today, where I was told that they could not do anything, because the control unit is the stationary heater of Mazda. I then drove to the Mazda dealer next door and told them so. I was told that they had the whole thing done with Webasto installation operation in case of such errors. The control unit was read out, but there were no mistakes. Then was sent back to the Webasto installation operation. I was told again that this is Mazda’s and that they can’t read out anything. If I understand that right now, my car has an ex-works heater, which can be turned on from a distance with a Webasto control unit, so that the interior and engine can get warm without the car being on, right? Mazda’s mechanic had told me that he didn’t hear any ignition. Maybe one of you could tell me where the problem could be and which workshop would repair it. Because the two workshops don’t seem to like it.
