The hydraulic pump is broken, and there are NONE in the USA, and apparently NONE in Germany. 8 days out, no part, no car. And yes, I've contacted PCNA to complain....
Respectfully, that's not exactly what it says. It's not a matter of damaging the system with undue pressure. Rather, if left lifted for a long time (days) pressure will eventually bleed out of the system and the front will lower. If you're parked over something solid when that happens the car could be damaged.

Of course I contacted PCNA on a Friday afternoon....right about when everybody was gone from factory in Germany. I will keep everybody posted....

Notice. Risk of damage through uncontrolled lowering of the front axel at engine standstill. In this particular system, the retaining position cannot be maintained in the upper position for an extended period without active replenishing of the pressure accumulator or engine operation. Always park the vehicle in the lowered position
That seems clear to me that there is risk of damage to the lift itself, not from being parked over something. One paragraph later, there is another "Notice". Risk of damage through bottoming of vehicle. Do not lower the vehicle when it is positioned above an obstacle
It would be nice to not have to remember to lower the lift each time parked, but this does seem to be what the manual is suggesting.

I agree with Mike, the system shouldn't be risking damage if it is left up, the car is risking damage is it is parked over something. You can raise the air system on my S6 too, but it will bleed off pressure over time and drop the car. You want the car parked in the lowest position so that there is no potential for damage on the car if it were to drop on a curb, etc.

Here's exactly what the manual (p. 145) states:
Notice. Risk of damage through uncontrolled lowering of the front axel at engine standstill. In this particular system, the retaining position cannot be maintained in the upper position for an extended period without active replenishing of the pressure accumulator or engine operation. Always park the vehicle in the lowered position

All that does happen is that air eventually leaks out, the reservoir (pressure accumulator) can no longer maintain adequate pressure without the compressor kicking in, and the car slowly drops. This won't damage the system but the car itself, or whatever is under it, could suffer damage.

We'll just have to disagree on the interpretation of the manual. I'm certain Porsche would not design the system in such a way that actual damage to the lift itself could occur if inadvertently left raised. The two paragraphs you quote aren't mutually exclusive. One describes what happens, and the other describes why the result could be bad. That's the way I read it.

All these lift threads remind me of the exact same topic in the 997 forum. Many, many issues. Guess they didn't get it right yet...

I think that's what RUF RS posted earlier. Since he couldn't get up his own driveway without the lift, and didn't want to park the car on the street, he decided to leave it at the dealer waiting for parts. Hope I got that right.....

Hi Macca, yes, car can be driven NO problem...EXCEPT getting in and out of my driveway is impossible, and not wanting to leave it on the street in front of my house...I left it at the dealer, awaiting the new part.
