Panamera - Gas Cap Replacement If at any time you get errors related to EVAP (small leaks, etc), chances are your gas cap is not holding pressure in the tank. This is one of most common ways to fail inspections. Then they sell you a gas cap at twice the price, charge you for half hour or an hour of time, and you end up paying $250 or more to get it done. Who on here finds this a familiar situation? Don't raise your hands (I wont see anyways...lol). Well, you can get this done in about 5 minutes, if you include a Author ciaka Category Panamera (970) - Common Fixes and Repairs Submitted 05/14/2018 02:04 PM

Is it recommended to replace coils with spark plugs on the PTT? I would assume not, unless coil is damaged in some way. Cayennes had them cracking. Thanks.

Thanks. I did see them, but arent these the actual jack lift points that go into your car, in case they get ruined? That is my understanding at least. I am looking for adapters that I can put onto jack lift which will fit into the lift points on the car. I saw folks making some, but hoping there are some for sale cheap. Thank you.

To wrap this thread up, I ordered replacement key based on serial number I had on original. Its been a week or so, but it will take about 3 weeks (must be ordered from Germany factory, who will order from UK manufacturer). Then I get it. Once comes in, I will use to remove 4 lugs, then throw it away (or sell to some sucker someone who wants to have some very specialty lock bolts).

So far I am able to do everything I need on Panamera, using the front car ramps (easy and quick). When I start doing other maintenance stuff, I wanted to see if there are adapters, which I can get, to put onto car jack or car stand, which will fit exactly into the Panamera lift points. I saw some DIY stuff, but before I head down that hole, I wanted to see if these adapters can be purchased cheaply. Thank you.

Can someone go over my take on how air suspension works on Panamera? I looked through the repair manual, scanned through many places. Hope I am accurate. NOTE: Please dont take below as absolute truth until I remove this note (Means someone with knowledge verified accuracy). The air suspension is closed system, filled with nitrogen 5. Min pressure of 16bar (235psi), max pressure of 17bar (249.9psi). Each air shock is connected to an air line. Each air line and air shock, have a Schrader type valve at air connection location, so nitrogen does not escape. Air lines connect air shocks to the valve block. The valve block is the mechanism which releases pressure form shocks, if one wants to lower the car. So if you sit in seat, press the lower switch (or PASM to make shocks softer), the ECU in back of your car will tell the valve block to open valves to each shock, allowing some nitrogen gas to come out of the shocks, making car lower/softer. The escaped, or bled out nitrogen goes from the valve block, into a gas tank, called the air accumulator. That gas sits there (does not escape to outside), until you get back into the car, and press a button to make the car higher. When you press button to make car higher, the ECU turns on the compressor (that is connected to the valve block and the accumulator), pumping gas from the tank, through the valve block, into each shock. This makes your car go higher or stiffer. Process repeats as you use the button, etc. In my conversation with dealer, I was told the air shock may slowly leak a bit of gas left overnight, but as long as the car raises in the morning, all is OK. That would make sense from view of not having all that pressure inside all shock bellows all the time. Leaking some gas back into accumulator tank (or through shocks bellow), would allow pressure to reduce, prolonging life of shock. Only when you enter car, and start driving it, does the gas process start, to pump into shocks for driving. How was that? I hope someone can straighten me out if not correct. Please chime in if you KNOW something is not correct. Thank you very much.

Through bit more research, I found cross reference between Shell Spirax gear oil. Attached links for datasheet to each, took snapshot of properties tables. Looking at both, I think using the Mobil Delvac 1 synthetic gear oil LS 75W90, will be safe. If anyone can chime in to stop me with reasons, please do. I would hate to learn this lesson expensive way. Thanks. Shell Spirax S6 AXRME 75W90 Synthetic Oil Datasheet Info: Mobil Delvac 1 Gear Oil LS 75W90 Datasheet Info:

...this means I must have been looking at the wrong cross reference. The PET 2 parts clearly state 75W90, with PN 000 043 205 30.

I was just able to confirm that Porsche Cayenne Turbo 2003-2006 uses same part number for gear oil. Porsche PN for Cayenne Turbo differential oil: 000 043 205 30 - 75W90 Porsche PN for Panamera Turbo differential oil: 000 043 205 30 - 75W90 Since both cars use same PN for same fluid, and since for years folks including myself used the Mobil synthetic gear oil LS 75W90, what say you? I guess I am looking for reassurance, even though my mind is kind of made up here (hey, gotta be honest). Thanks again.

I came across a cross reference where the Shell TF 0951 gear oil (Spirax), was on same cross reference line with Mobil Synthetic gear oil (same certifications: API GI-5; MACK GO-J PLUS). Does that help in saying the Mobil synthetic gear oil 75w90 would be fine? The viscosity of the OE gear oil is same - 75W90. Hoping to do the change this weekend. Thank you.

On Cayenne we used Mobil 1 75W90 Synthetic Gear Oil LS. Is it safe to assume that will also apply to Panamera? What exactly is the TF 0951? Is that some rating from Shell? Would love to understand.

Have been doing more research which answered some question and created more. So my new questions are below... 1. Where is the access point I would use to evacuate entire air suspension system of air and moisture? 2. I assume once I know #1, I will know which access point is used to fill the system with Nitrogen. 3. How would I go about checking pressure in the air suspension, to see if it needs top off with Nitrogen? 4. I really would love to get instructions on how to rebuild the compressor for air suspension. Mine is not failing and not running all the time (actually do not hear it run all that much), but I do want to remove the compressor and replace any rebuild parts to refresh the unit (will make the pump more efficient and extend its life). 5. What role does the valve block do? Is it just air distribution or does it actively manage where and how much air goes to a shock (this would mean possibility of fail point if valves do not open correctly). Thank you for help.

as they say, what comes up must come down. Its down.

Did the bumper removal yesterday. I would never pay someone $500 to do it. Removal is super easy. Save yourself a bunch of money and DIY.

Started looking for info/details on changing differential fluid for the PTT. I plan to do both front & read diff. Hoping it is as easy as on Cayenne. If anyone has seen a link to DIY info, has instrucitons details, I will greatly appreciate. Again this is for front and rear diff. I will be doing a DIY for it, so that others can benefit. Thank you.

Does anyone on here do air shock maintenance on the bags (rubber)? I mean putting some rubber lubricant that will keep the bags malleable, and help them stay elastic and not brittle? I figure that may be a good maintenance item to do on each shock. What do you think? I am willing to try something, but need to find a suitable lubricant that will not interact with the rubber to help decompose it. Thanks.

Through some searching I came across threads (in multiple forums) about Panamera air suspension being filled with Nitrogen 5. I am not exhibiting issues yet, but have been reading many many posters talk about their issues with shocks, so I guess I am preparing for eventual repair. Can someone chime in on this, to confirm with certainty? Also have questions: 1. What is the exact reason for using Nitrogen here? Just corrosion management and inertness of gas? 2. What if you do not fill with Nitrogen and let compressor use regular air? 3. Can someone confirm that the air shock has to be filled with gas to specific pressure (I read between 16 and 17 bar - max of 249.9psi) 4. Is there a special process to do the fill? One shock at a time or all shocks connected and filled at once? 5. Where did you get your setup to do your own fill? 6. How do you compensate for gas trapped in line when filling the shock? Thank you as always.

I was pleasantly surprised to see battery on Panamera is in trunk, unlike in Cayenne, under driver seat. Easier to get to and do stuff with. You know - if you need a quick way to weld stuff, etc.

Cool. After I tried it a few times, thought it through and turned off full time as well. I know engineers are well meaning folk, but IMO this situation warrants the OFF position for the feature. Wonder if PCNA will give any $$$ back for not using the feature. lol

I was just at the dealer here in Austin. Discussed suspension among other things. He said the shocks sometime fail (bellows no longer hold air tight when worn). This causes often the compressor to work all the time, burning it out. Told me it is quite normal to park Panamera in garage, and overnight it would lower (some air loss). However, as long as when car is started, it pumps up, it should be good to go and continued to be used. I am getting no issues on any PTT suspension yet, but noticed takes longer than Cayenne turbo to inflate/change level. So started contemplating doing recondition of compressor internals. See kits for about 60 bucks. Worst case wont make a difference. Best case, will pump more efficiently, therefore turning on less often. BTW unless car is engine stopped, it is kind of hard to hear that compressor turning on/off. Does anyone else hear it well when engine is on?

The car I got just had a brand new battery put in (checked the trunk and it was dated end of 2017 for manufacture date). So I appear to be covered. Reason I put it on the list is I continuously see people putting their cars on trickle chargers. If the car is driven every day there is no reason for that, since battery gets charged on the drives. Am I not thinking correctly here? Thank you for posting up.

I have questions about the auto stop/start feature on the Panamera. When it is enabled, if car stops at a stop light, etc, the engine automatically cuts out (leaving electronics on while engine is off). When light turns green, driver lifts foot off brake, and engine restarts allowing driver to resume driving. Isnt continuous start/stop of the engine, many times during any routine driving trip to work/home, a bad thing for the engine? Typically, starting is one of the more harsh things done to an engine. Am I incorrect in this train of thought? If continuous stopping and re-starting is not good for the car, why would a driver want to be using this feature (other than uninformed drivers thinking they are cutting down on pollution)? Thank you for your enlightenment.

I have been looking, and so far only found it at another online place autoa*****a.com for 12.40 plus about 6 bucks shipping. It appeared to be showing 12.40 (I assume) for each hook. You quoted 11.81 for all 6, where is that found at? Tried sunset porsche parts and it could not find item with this PN. Thank you.
