Air suspension for dummies
I've had my 04 CTT for four months now, and although it spends most of it's time in the garage because it's summer and we have an M roadster, I never really got round to figuring out the air suspension 
My Cayenne handbook doesn't help much and I haven't found any postings on this topic here to simply explain how the difference settings should be used and what driver feedback this gives.
I presumed that the 'comfort' setting should be softer, yet I could still feel the road vibration on the motorway and it didn't seema any different to the other settings.
The sport setting I thought should be tighter with a lot more responsiveness, however shifting into the sport mode on the motorway didn't seem to make any difference to the ride or hadling either. Overall I am underwhelmed. Am I doing something wrong or does anyone have suggestions for a particular type of drive terrain/ style which will make the differences obvious to me..
I hope it is not broken as I didn't buy from an approved Porsche dealership and I haven't taken it in for a service yet
Thanks for your help.
