    Welcome to RennTech You can become a contributing member by donation, by taping on the "donate" icon at the top of the page. Becoming a contributing member does not give you access to the PIWIS system, which is Porsche's factory diagnostics system. To personally acquire a PIWIS, you need to contact Porsche directly, and be prepared to cover the first year's lease cost of $20,000. An alternative it to subscribe to Porsche's TSI online service, which would give you access to their copyrighted service information, such as interior assembly diagrams.

    Disconnecting the battery will not clear all types of codes or MIL's, there are several that have to be manually cleared with an appropriate diagnostic tool. Many fault producing codes that can be cleared by disconnecting the battery will promptly return because the fault is still there and needs to be corrected before the MIL will not return.

    Asin makes both manual and automatic gearboxes for several different car brands, ranging from Porsche to Nissan, Honda, and Toyota. They are also one of the largest manufacturers of the CVT transmissions showing up in many brands of vehicles.

    No one is suggesting that there are no other near equivalent fluids out there, but without a detailed factory spec sheet, it can be difficult to impossible for the average person to figure out which is which. Porsche is also well known for using unique lubricants in their manual gearboxes which are literally made to their specs. That does not mean there aren't other lubes that would work to some degree, but most find out the hard way that using aftermarket products lead to a litany of operational issues, and quite often damage as well. You might be surprised how many times we get cars in that had been switched to other products either by their owners or another shop, and problems resulted in the car coming to us because we use only the factory lubes. Several years ago I approached one of the known suppliers of these lubricants and was told outright that what they make for Porsche is unique to Porsche, and cannot be sold to anyone else because of exclusive marketing agreements between them and Porsche. As the result, we still buy ours from Porsche, albeit in drums, which are plainly marked as made by one of two companies. Based upon what I have been told by someone from the Porsche factory, they are (or were) ZF. As Porsche often uses more than one supplier, they may also some that come from other suppliers; but I was told ZF.

    Our experience is exactly opposite; we see vehicles after someone has used the wrong fluids and they have either crapped out after very few miles, or were never the correct spec in the first place, often resulting in catastrophic damage. These gearboxes are ridiculously expensive just to buy either new or used, much less the labor costs to pull and replace. Porsche does not sell parts for them, only complete gearboxes, and very few shops have the tooling or expertise to work on them. In my world, using another lubricant without fully understanding its specs is running a very large risk on something that can bite you big time directly in your wallet.

    I just love it when people in their inexorable quest to try and save a buck buying cheap unknown spec lubricants for their $100K vehicles rather than getting the correct products; it is logic like this that keeps independent shops in business, repairing the damage.

    You can buy the part Pelican is selling for $661 for $439 on Amazon: Porsche AC compressor with clutch Pelican prices are rarely any kind of good deal.

    You can try for a used one online, or from a wreck.

    We use the Durametric system in the shop every day, generally without incident. Owen is trying to walk you through a firmware update which should resolve your issues. Did you try what he suggested? We looked the other system and found it lacking in several areas, which is why we stayed with Durametric, which has about 80-85% if the functionality of the factory PIWIS system.

    Most Boxsters came with one or more empty slots in the horseshoe trim panel, and most switches are simple on/off types.

    Welcome to RennTech I have to ask a question: Is this legitimate Durametric cable, or one purchased cheaply online?
  12. JFP in PA
    Welcome to RennTech Unfortunately, there are not a lot of options on this as most rebuilders don't carry "ready to go" exchange sets in stock as there are not a lot of these cars about, so demand is limited. That limits you to either buying another set or parking the car for a few days while someone goes through yours.

    Sunset Porsche is a board sponsor, and offers some of the lowest parts prices you will find anywhere: Sunset Porsche

    While it is never a good idea to start one of these engines if you know or suspect the cam timing is off, once you get beyond around 12 degrees you are in trouble.

    Sometimes you have to cut the bolts away and press out or drill out the stubs and replace them. Other times you can cut away just the nut and stave the studs. When they really get nasty, like daily drivers in the Northeast with tons of salt on the road, you don't have a choice. Some have taken to replacing them with stainless steel.

    Welcome to RennTech Did you either recently clear trouble codes on the vehicle, or disconnect the battery?

    Activating the ABS/PSM pump and control system while bleeding is only required if air has gotten into the control network. During a normal maintenance flush, it is not required.

    Lithium based batteries will not quickly spread into the SLI (starting, lighting, ignition) applications for two profound reasons: The exsisting recycling chains mandated by the EPA cannot recycled lithium based batteries as lithium poisons lead and makes it useless for batteries, which is by far the largest application for recovered lead. That means lithium SLI batteries would require a totallly separate recovery system, which is not economically feasible. Lithium based SLI batteries are expensive, making them unattractive replacements in a mareket where car owners tend to show very low price elasticity (read most will buy the cheapest substitutes they can find).

    The fuel pressure test port is under the engine cover (which needs to be removed). step. Once you have the cover off, the "fuel gallery" is the y-shaped tube (carries the fuel around the injectors) that runs on both sides on the intake manifold. It's the only silver metal tube there. On the very front ends of this y-tube, you will see black twist-off covers (similar to those found on a tire valve stem). Remove these and you can access the relief valves (they look like the inside of a valve stem). off, the "fuel gallery" is the y-shaped tube (carries the fuel around the injectors) that runs on both sides on the intake manifold.

    What you should be doing is the fuel system test I suggested. If you cannot do them yourself, take it to someone that can. Aimlessly swapping out expensive parts is only going to make your wallet easier to sit on.

    You need to start by running a fuel pressure and volume delivery test.

    The biggest advantages of AGM technology are their vibration resistance (a major battery killer, particularly in cars with stiffer suspensions), deep cycling recovery capabilities, superior cold cranking, longevity, and total lack of corrosion, which is critical on Porsche's due the battery locations. We have customers that are regularly seeing 2X life expectancies with AGM batteries, with absolutely no signs of any corrosion in the battery area. Their ability to be mounted in any position is a neat feature, but one that is rarely used; but their other capabilities are something owners can utilize every day.

    Good grief! A shorter list would be what is still working, which isn't much. I would approach this with a great sense of trepidation as cross wiring or shorting circuits can end up permanently damaging some of the myriad of electronic controllers in these vehicles, which means they still will not function once the wiring is corrected. In many cases, your Durametric will not be able to recode the modules, even if they are still in working condition, requiring the use of a PIWIS system. And if they are irreparably damaged, the PIWIS will not be able to save the day either. I'm afraid this may turn into the perfect example of a money pit, and a poster child for why those who are not equipped to work on these vehicles, or do not understand their systems, should not be allowed anywhere near them. It sounds like what they did was to butcher a fine vehicle out of ignorance or hubris. What was originally at fault is probably now hidden behind the damage they created. Good luck.

    Any sufficiently advanced technology is indistinguishable from magic............
