If it's been more than four hours, call a doctor!

OP you were so winning the humorous post of the week until we realize you really, actually meant it.

According to the fine print on the back of the packaging, medical attention is definitely required if you remain in the lifted position for prolonged period... (sorry I had to do it)

Back on topic, the lowering of the car is triggered by the opening of a "dump valve". That valve is programmed to fully open at driving speeds (it was some 50-odd km/h on the 997). Can you go back to regular height that way?

Our pump's circuitry is designed in a quirk way: the electronics won't let you trigger the dump valve unless the car's reached a certain height (and a certain pressure maintained in the lift tank). If you have a failing pump the car may well never reach that height. As a result you're constantly stuck in between while the pump labors away furtively... until it fails entirely and there's no lifting of any kind.

Insist on getting a warranty replacement--the pump unit IS a consumable and if it's showing problems early, total failure is only a matter of when not if. The hardware alone is over $8k--I'd hate to be out of pocket for that.

Thank you ALL for your replies, both with, and without humor! Laughter IS the best medicine! I've driven it, (with the door closed!) up to 40 mph, the messages keep insisting on getting service, and the lift stays up.
I saw a brief reference of tab that said tighten fittings AND change switch, anyone have more info on this?

Thanks for the description; that's good to know. If the pipe connections aren't secured isn't it possible that could also prevent pressure from building high enough to reach maximum height, the dump valve wouldn't trigger, etc.? Given that there is a known campaign for the pipe connections it seems to me that might be a reasonable place to start.

Mike, that first part just sounds hilarious!

Nick, get your mind out of the gutter.....

Sorry Mike, the wording was perfect. I hope and pray my dump valve never fails....LOL!

Update, went for service at dealer today, 38 mph 90 minutes. Tech diagnosed bad solenoid, via Porsche specified troubleshooting procedure, about 2.5 hours, seat out, etc.
Part only comes as entire lift system, with pump. Arriving from Atlanta tomorrow and being installed.
Details at 11...

Amazing that the whole thing needs to be replaced just for a solenoid! Thanks for the update Milban.
Here's hoping it doesn't fail again. I'm sure the "to lift or not to lift" thread will say here's why you
don't want a lift. I'd hate to have mine go out far from home. It would take a long time to get back!

Here's my saga with the lift issue....

For those with long term interest in the car, reason to not have this option.

i said that over and over since day one. but no, they all want viagra cialis....

if my lip hits the curb so be it. i couldn' care less. i hate the lift thing

Mmmm. That little chestnut. Dont get me started now. 10,000 miles no lift no regrets....(but my driveway is not the challenge some have)

On my 997 RS I had the experience of the lift raising the nose of the car whilst on a fast lap
of the Nordschliefe. It was pretty hairy, especially going over the bump at Plantzgarten 2 !,
suffice to say I parked the car up in the main car park. I made it out onto the nearby roads,
and found a bump in the road to effectively shock it out of its position...this worked. To be
honest, not a great call because I reckon that I put the tracking out by doing this.
I called my Home Dealer in the UK, and they talked me through disconnecting the relay
(under the carpet -rear window).
This in essence killed the lift system, so there would be no further occurrences of the lift
activating on its own. That in itself was quite a task, as there's not a lot of room between
the seats and cage to facilitate its removal !. Once back in the Uk, the car went in for
investigation, and the entire lift system was replaced under warranty....hey ho !.

You have to remember, guys that love the lift hardly ever drive their car, and they most likely don't venture far from home.
If they did, they would realize that all it takes is one malfunction, and you're funked.
Scrape on...
