    Could be; I would check the system harness (both ends disconnected) for a short to ground before replacing the motor. 😉

    Welcome to RennTech Does the spoiler only blow the fuse when you hit the manual switch, or does it also do it when it goes up at speed?

    60Nm (44 ft/lbs.)

    Several years ago, Porsche released a warm idle low oil pressure update for the M96/97 engine oil pump that consists of an upgraded spring and piston to address this type of issue. Cheap and easy to install (Piston: 997.107.125.01 ($ 5.00) Spring: 996.107.127.53 ($10.00) Gasket: 996.107.123.50 ($ 2.00) :

    Welcome to RennTech I'm not really sure what you are asking, could you provide more detail?

    Then I would still suggest checking the air/fuel ratios at the time the problem occurs.
  7. JFP in PA
    One of the primary cold vs. warm differences on these engines is the air/fuel ration. When it first starts, the mixture is richened (open loop) to help it run well, and it then leans out (closed loop) when it warms up. If you had a small vacuum leak in the intake system, the cold enrichment of the mixture could be enough to let the car run smoothly; but when it goes closed loop, the mixture is too lean, causing random misfires. You can determine this by monitoring the cold air/fuel ratio vs the warm ratio; and if it is a vacuum leak, find it by smoke testing the system. Good luck; this type of problem requires time, intuition, and focused diagnostics.

    You shouldn't have to remove it, just open it and get the stuff inside out of the way. You can see the four bolt heads in question above the tire it this photo:

    Welcome to RennTech To remove the rear struts, there are 4 long bolts under the spare tire cover in the trunk area (different from 955/957). The rear struts are quite easy to remove, but installation can prove difficult without a second person helping. Good luck.

    Welcome to RennTech Try posting your request in the section for radio codes, and you will get a prompt response.

    All of Porsche OBD II informations is copyrighted intellectual property, so no one can publish or post it online without incurring the rath of PCNA’s legal department.🤥
  12. JFP in PA
    The only source for OBD II code data for a 991 is in the PIWIS system (Porsche stopped printing this type of data around 2004 model year). It can also be obtained through their online subscription service, PIWIS Tsi.
  13. JFP in PA
    Internally, Porsche uses and numeric fault code system that are not in the standard OBDII format. The factory OBD II manual for the car model had a “translation” section that converted one system to the other. Unfortunately, these manuals were rather expensive (around $2,000 when the car was new), and no longer in print, making them rather scarce. And as they are considered the intellectual property of PCNA, reproducing or publishing them would invite legal action.
  14. JFP in PA
    Amazon (amongst others) sells them.
  15. JFP in PA
    Welcome to RennTech Looks like what Porsche calls "Engine Coolant Hose - Porsche (987-106-522-02)", about $65 at retail. Word of caution: Have dealer check the part number against your VIN, there were more than one version used.
  16. JFP in PA
    Yes, it can be done, but you need to pay attention to potential CAN Bus errors, and you will also need to upgrade to an LED compatible flasher to stop "hyper flash" rates from the turn signals.
  17. JFP in PA
    +1 See this all the time.

    It is turning over unevenly, like it has compression some of the time and not others. Are you absolutely sure the cam timing is correct?
  19. JFP in PA
    We do this for a living, and have never seen legitimate IMS retrofit instructions that says to rotate the engine in between the installation of the hydraulic tensioners. It is unnecessary,and extremely risky as the cams could jump time when rotating the crank with any of them out.
  20. JFP in PA
    Welcome to RennTech You need to get the car scanned with a Porsche specific scan tool to find out what error codes or messages are present. Without that information, anything else would be a guess. Good luck.
  21. JFP in PA
    Most modern headlights have plastic lenses that have UV resistant coating on them. Polishing the lenses removes that coating, causing them to "fog" more quickly in the future. Several companies advertise they have recoating's that replace the factory, but we have yet to see one that actually works. As for damaging the electronics associated with the headlights, that seems to be more of an "old wives' tale" than anything else. It's possible that a buildup of static charge could happen which under some obscure situation could upset something, but again, never seen it happen.
  22. JFP in PA
    Not sure the enthusiast version can do this; you might want to contact Durametric directly and ask.
  23. JFP in PA
    I would check the chain designs and the gears on the shafts; Porsche changed design on the chains & gears, and they are not interchangeable, and also have to match the gears on the Vario Cam.
  24. JFP in PA
    Extracting the IMS bearing from the shaft will irreparably damage it. Get a replacement.

    Under the console.
