  1. 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:
  2. 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.
  3. Welcome to RennTech Try posting your request in the section for radio codes, and you will get a prompt response.
  4. 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.🤥
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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?
  10. 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.
  11. 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.
  12. 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.
  13. Not sure the enthusiast version can do this; you might want to contact Durametric directly and ask.
  14. 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.
  15. Extracting the IMS bearing from the shaft will irreparably damage it. Get a replacement.
  16. Contact board sponsor Sunset Porsche, they have a great website and carry it in stock. The factory stuff is full synthetic and has a long life. 😉
  17. It is your car and your money, and you are the only one that will have to deal with the outcome of that decision, but the car does not use a GL anything oil, regardless of what the boys at Exxon tell you..........................
  18. They really aren't once you understand how they work, then they just pop out.
  19. The spoiler cover is held in place by three small plastic push pins: Push the pins out with a small straight punch or the end of a small drill bit and they will fall into the spoiler trim cover. They are reusable, so recover them. Then you can lift the top cover off the spoiler. Then check the 2 Allen bolts that hold the metal body in place. You need to check that the metal body for the spoiler is centered is the opening an/or loose in some way.
  20. Porsche has typically used gear oils that are designed to their specifications, particularly in the five speeds because of the synchro ring materials of construction. As the result, the factory fill gear oils lack any API or "G" gradings because they are unique. A lot of the smaller aftermarket suppliers claim they have "equivalent" products, that in reality are not. Over the years, I have lost count of how many gallons of aftermarket gear oils we have drained out of customer cars due to complaints of poor shifting, particularly in the cold, noise, etc. And that includes a lot of Redline, Royal Purple, and Amsoil products. And except for transmissions that had sustained damage while using these aftermarket products, every time we switched the car back to the factory fill, all the customer's issues disappeared. Years ago, we contacted all the major gear oil vendors looking for a true match to the factory gear oils; Mobil 1 summed up best when they told us that "Porsche uses totally unique gear oil formulation requirement's, which are made to their specifications, and which do not match any of our off the shelf offerings. And as Porsche represents such a small segment of the overall market, we will not be attempting to replicate their formulation requirements."
  21. People tend to think that all Porsche's are laid out the same way, which could not be further from the facts if you tried. Glad you found it. And you do not need a special connection for the Ctek unit; these cars were designed so that the cigarette lighter socket stays hot all the time so you can plug the Ctek into that, run the wire out the driver's door thru a recess in the lower seal on the bottom of the dour almost directly below the door mirror, close and lock the car with the alarm on, and still have the maintainer keeping the system charged. Every Boxster made is this way 😉
