Hi Everyone!

Last Friday I became the happy owner of a 2008 Cayenne Turbo. It has 120 000km (74,5k miles) on the clock, from the first owner and I purchased it from the local Porsche Center.

I noticed an odd thing during the weekend however. The right side of the car sits about 15mm (that's roughly 0,6 inches) lower than the left side, both front and rear. This tilt can also be felt while driving and the car pulls slightly to the right, but is not really noticeable when you stand next to the car.

The air-suspension rises and lowers normally, gives no faults indications and does not drop any further during the night.

Has anyone had anything similar? Could it be something to do with PDCC and not the Suspension?

The car is going in Monday next week for an inspection and recalibration of the air-suspension (Dealer claims it was totally straight when they did the wheel alignment when I picked it up on Friday, as it is not possible to do the alignment otherwise).

 

The air suspension calibration procedure can be completed with a durametric tool. Arbitrary numbers can be entered to an extent. If the vehicle isn't on a level surface when the measurements are taken, this can happen (or an error in manual measurements). I'm sure the same is possible with the tool they would use at the dealership.

Congrats on the purchase! Post pics!

 

So, got the car back from the dealership "now it's totally straight". Well, now it leans to the other side instead.. the suspension as a whole is also slightly lower in normal mode than it was before (notably easier to get in to the car).

Is the adjustment really some higher science or why can't they get it right? And this is the Official Porsche Dealership I'm talking about.

 

It certainly is not rocket science. Or physics. Or addition. You park on a level surface, press some buttons, take some measurements in MM and enter said numbers when prompted.

Now if you want to lower it, some addition and subtraction can be added to the party... No reason the dealership shouldn't be able to figure it out.

 

A little update on this case.

So, after the last calibration I reported it was now leaning to the other side instead about 1cm (0,4inch), but additionally I later noticed that the whole front was 2cm (0,8inch) lower than the rear (hence car felt lower). The dealership had a go at it again (they said the 957 is slightly more tricky than the 955 to calibrate actually), and they found that for some reason when doing according to the factory instructions my car leaves the front 2cm lower than the rear, even though the suspension and sensors seem to work fine. They could not figure it out.

They eventually ended up just measuring each corner from the ground to the wheel-well (not how Porsche instructs), and now it stands straight in all corners...still baffled by this, but I guess all good now.

 

Computers.... Basically computers in anything are always ****ed.

 

Interesting... I noticed something similar since last job.

Also leans forward a bit just as you described.
Something I'll deal with next oil change. It's not really troubling my wife.
