My 2010 GT3 front lift system is not working any longer, once car is started & run for less the 1 mile it turn on the FRONT AIR LIFT FAILURE sign. Took my GT3 to my only authorized Porsche dealer and was told the need to replace the complete solenoid unit (over $12k only on parts). I really don't need it any longer, just prefer to buy front lips instead of spending over $14-15k on new system with installation. I ask the service advisor to turn off the system and was told it can't be done. Some time ago spoke with a Porsche tech who lives now in the US and works in a Florida Porsche dealer and told me that the system can be turned OFF.

My question is how can I turn off lift option in ECU with Durametric?

Any help is appreciated.

Requires PIWIS coding. Not possible with Durametric.

Rick GT3

thanks

I did email Durametric and was told they "have no information regarding the procedure to disable / uninstall this system".

Now to buy or rent a PIWIS.

anyone had bought a PIWIS on line? ej: 2 links of available PIWIS

cheaper to have your dealer code it off.

Def much cheaper, but it sounds like his current service advisor said they "can't" do it and would rather have them replace the whole lift system instead of helping their customer with what they actually want.

The same happened to a friend here in Spain with his MY2010 GT3, he almost collapsed when he knew the full device replacement price...

But a very good mechanic here opened the system to check parts, discovered what was wrong and replaced the faulty components. At the end, about 400 € including parts, labour and investigation...

there's only ONE authorize dealer in PR.

Rick GT3

that's correct, I told service advisor that air lift system is an OPTION!!!, they are able to turn off the system, but no they still insist that can't be done.

thinking about buying a PIWIS and sell my Durametric Professional, with an updated PIWIS will be able to diagnose and perform more stuff than Durametric.

A current PIWIS with the latest software for the 997 series can do much more than a durametric. You need the lastest "last gen" model - the newest one supports 991 and the later cayennes etc. For example on the 997 you can do emissions adaptation with the PIWIS to "quick pass" all but 1 or 2 of the tests. You can get access to every module for coding, etc.

And yes, this function can be turned off. The pump is located in the center tunnel behind the rear wheels. It is electric has has 2 pipes (I believe they are air) that go to each damper. These fail constantly. The units are not hard to remove. Theory my shop has is the placement is right next to the coolant piping and the thing gets hot and just eventually fails. i'm getting the failure may not be complicated, so maybe the unit can be repaired. And yes, it is EXPENSIVE.

Every 997.2 that had lift that has/had aftermarket dampers has the system disabled. I'm guessing in PR your dealer options are limited. Does any other specialist have a PIWIS?

This isn't a direct response to the original post, but I would like to reopen the topic of diagnosing the front lift. Contrary to what seems to go as common knowledge, the front lift system is not a single part number in the PET. There are several components that can be replaced - its my belief that the failure many have reported the 'lift only lowers when exceeding 30mph' failure which many have attributed to a pump failure is actually a pressure switch failure that is easily replaced. I am seeing this failure where I hit the button and the front raises, but LIFT doesn't appear on the display and the car won't lower when I hit the button. What I've noticed which I think is weird is I can park the car for 3 hours, come back out and when I turn the car back on LIFT is now illuminated and the car lowers with the button fine. Something that would be explained by an intermittent switch closure failure.

From digging through the PET, I see 3 pressure switches in the pneumatic lift system:

997 341 964 90 - pressure switch until pump 000 111
997 341 967 90 - pressure switch from pump 000 112
997 341 963 90 - pressure switch
997 341 965 90 - pressure switch

From digging around on the interwebs, i think one of these pressure switches registers when the pressure in the shock absorbers has reached 13 bar, and causes the LIFT indication to appear on the display. Until this pressure switch has activated, LIFT won't appear and pushing the button won't cause the car to lower. I believe this is the pressure switch that causes the failures described above - I'm just not sure which of the above part numbers is the correct one to replace. If we could get more clarity on what each of these three switches do, we'd have something else to try besides the $12,000 replace everything option!

that would be great if we can figure out the easy/cheap things to try out if the system fails.

i think the lift in my car was repaired once under warranty by previous owner. it has worked fine for me so far and i actually use it every time i drive for getting into and out of my parking area, so would want to fix it when/if it dies again.

I've started a new thread on the lift issues, 2 dealerships were unable to definitely fix my issue. The first one replaced a "sensor", which I would guess is one of the pressure switches. The second dealer did not give me a definitive answer. My car was still under warranty at the shop-after I left, I got the "Lift Malfunction" message, which will not go away even if you leave the lift switch alone. Disconnected battery to try a reset, no go. I'm still disputing this with PCNA, and would like a definitive answer on which parts failed. I'm sure the Porsche workshop manual describes procedures to test and diagnose, but none of the service department personnel provided me a diagnosis on paper, and that through PIWIS I can get a printout.

I will continue to insist on 100% parts and labor, calling PCNA again right now-
