Porsche 997 2008 Map PCM button not working

[alag20]

Hi Guys,
I need some help with my 2008 Porsche 911 Carrera 2S 3.8 Convertible UK.

I am having issues that the Maps button & Phone button are not working on the PCM itself. I can get through them if I press the Menu button on the steering wheel which circles through all of the options. I hope it is something simple?

Please help as I love my car and Porsche want to change PCM unit itself for 2K but I think it should be a simple fix??

Hi

If you press 2,4 and 8 on the telephone key pad it reboots the pcm back to orginal settings. Worth a go and free. Good luck

That should be 1, 4 and 8.
