I'm struggling with the car pulling to the left or right after several suspension and tire alignment procedures done by Porsche.
This is a very subtle issue and depends on tire temp/pressure but it's there.
They claim most of EV Macans "wander" a bit meaning pull to the left or right.
Best they could to is to minimize this but still it means the car does not keep a straight line under some conditions.
TBH I'm tired of this and all the other problems with this car but want to give it some more thought.

Can I find all the suspension geometry settings that are considered the norm by Porsche?

I'm asking because I've seen the printout after the alignment and it shows all green values but some of them do not have a reference value (or just 0) and it includes Thrust Angle and SAI (Steering Axis Inclination).

I had a similar concern/issue. Was told the electric steering is more sensitive, whatever that means. Tech took car for a drive and said it’s normal for our crowned roads. I then asked them to check tire pressure. The left front tire was 3lbs lower than the right and others. Once air was added it was resolved. That’s said, I do think the electric steering probably increased sensitivity to tire pressure differences as I noticed the change over time. Good luck with your situation. I hope it’s something simple.

Don’t know what you are asking but I am surprised you are having that problem. Mine doesn’t pull to either side at all!
I learned to drive on a used manual Honda Accord many many moons ago and it always pulled to the left regardless of how many alignments I did, so I understand how frustrating it can be.

Mine pulls to the right and the dealer did not even check when I brought it in for another reason because they said I have to wait for the suspension to settle so I will have to go back again.

mine certainly does not pull.... But with crowned roads, some drifting...rather than pulling, should be expected.

You adjust the caster to account for crowned roads iirc... But maybe you should just take the car to a performance specialist shop (race shop) for a 2nd opinion.

I'm sure there's a database for the techs to pull this information from...
