Well, other than being slightly temperamental with the managed motorways gantries, with a 8/10 success rate, it seems to be working reasonably well! Thanks so much for the info on the fix! I'll still not trust it completely though but it's a lot better than not working at all! lol

Just come across your message concerning Assistance System Faults
Does your Macan show any Traffic Signs alongside the Speed Limit sign ?
I have had my Macan 4 with Innodrive for 6 months now.
It has never shown a Traffic Sign, and has been back to dealerbmore than 4 times to solve this issue with absolutely no success.
Neither the dealership or Porsche UK appear to have a clue how to fix this long-standing fault
Anybody else experiencing this issue ?

It’s a different config on UK spec cars, but thanks for the info

Please make a screenshot of your assist settings as described. There is no different UK spec

Does your Macan show any Traffic Signs alongside the Speed Limit sign

Yes it does, BUT this happens only in the left most dial, when configured to show the speed dial. This is not the most useful of dials for me, and I hardly ever use it, so it was a surprise when these popped up one day. The most common ones I see are the 'No Passing' signs that, in the USA, go along with the solid lines on the road.

Don't know about what it does in the UK, but the center of that dial is where you will see them

I’m looking forward to see how the driverless buses and taxis will cope with the crap signage in the UK when trialed early next year - good example above !

So based on everything I'm reading here my Innodrive is not functional. The "route" option is greyed out and can't be selected. I see no difference in ACC no matter what options I do select. It doesn't slow down for curves etc.

I noticed the other day that my HUD displayed the 5 MPH speed limit in effect at the car wash correctly.

route: only active with porsche navigation
to get innodrive you have to activate it in vehicle settings
but read your manual and watch the new instruction videos at:
