After the stuck on Porsche logo on the PCM , I Tried the 2 finger reset on the screen and has brought me to "engineering mode" with four options however clicking on any one of them does nothing and i cannot exit it.
No Radio,phone etc
Any Ideas ?

Mine has done that but it went away after a few minutes and attempts. Not sure if this is the same as yours but hope it helps.

BTW - I was still having to do the reboot about 20% of time I got in car even after the first software upgrade. I got another software upgrade about a month ago and haven't had an issue since.

The bottom option should allow you to exit (once expanded)...

That’s an insanely high percentage. I have not gotten the latest update but I almost never have to reboot my PCM. Glad to hear the latest software fixes your issue.

Are you interacting directly with the screen or with the "pad"? Tap the "+" next to "Reboot to normal mode" direct, if you haven't...

When in engineering mode the button touch is only optimised for a driver in the left seat.

Hop in the passenger seat if you are in Ireland, UK, Australia etc and those options/buttons will magically become much more responsive.

Trust me!
