PCM problems - hardware and software replaced
Posted: Wed Oct 09, 2019 9:41 pm
About a month after taking delivery of my 2019 Macan last December here in Spain, the PCM developed problems: the navigation system and speed limit display would stop working (always at the same time) with the messages "initiating navigation" and "speed limit display limited" appearing. The navigation started promptly but after a while during driving would freeze and start initiating. It would only start working again if you stop the car and turn off the ignition and wait for a while. This did not happen every day but sometimes several times a day. P service could not diagnose any problem despite several visits. Finally, they advised me to get in touch with P Madrid and file a complaint which I did. After some correspondence with Madrid and sharing fotos of the messages on the screen, the local OPC called and asked me to bring the car back to them. I had taken a few short iPhone videos of the malfunctioning screen which I shared with the P service and they said they will share with Madrid/Germany. After a week at the service got a call saying that P Madrid/Germany had decided to replace both the software and the hardware of the PCM system (under warranty) and the parts would be sent from Germany. After another week, got the car back and now seems to work fine, fingers crossed.
I was told by the OPC that they had only had one similar case, and that was with a new Cayenne. It therefore seems to be a rare occurrence and is unlikely to result in a recall. Also, have not seen anyone else on the forum reporting this problem. I guess I had some bad luck but hope all is now well with the lovely car. Wanted to share this in case anyone else encounters this problem with the new Macan.
