  1. The immobilizer functions by shutting off power to both the fuel system and the ignition.
  2. Welcome to RennTech One of the functions of the immobilizer is to shut off the fuel system, so if you are getting intermittent codes for the unit, I'd start there. Your voltage reading also is questionable, you should be seeing around 12V.
  3. Welcome to RennTech Porsche discontinued printed service manual more than ten years ago, so copies are hard to come by. The only decent and current "online" manual I know of is Porsches PIWIS TSI system, which is pricey. A decent print manual is the Bentley Boxster manual. Good luck.
  4. The AOS in the sump are an entirely different system design than the external one that controls the sump vacuum levels, and does not use a membrane. I can't honestly say that I have ever heard of one of the internal AOS units failing. If you have already replaced the external unit, and it has failed, I would be willing to bet it was an aftermarket unit (often sold an OEM style unit) which are well known for incredibly poor build quality and short life spans. Many shops, mine included, only use the factory piece.
  5. Most likely you broke the cable ends or the drive that lowers the top. You are going to need to manually get the rear panel open and access what is broken. Good luck.
  6. The best thing he could do is to have the car scanned with a Porsche scan tool, it will show the source of the last 10 alarm faults.
  7. The car’ s dash has a radio theft alarm circuit built into where the radio sits; left unconnected it triggered the alarm to beep.
  8. No, you are looking for an organic reason the engine is overheating, so even though it is not leaking, a pressure test would reveal the presence of mechanical flaws such as cracks, which the early Boxsters were famous for having, and which caused overheating. I would also be testing the atmosphere above the coolant in the tank for the presence of combustion by products, another indication of possible cracking. You should also have the car scanned with a proper Porsche scan tool to evaluate the actual coolant temperature vs. what the dash gauge displays. These temperature displays are well known for being both inaccurate and non linear.
  9. If you look two post up, Loren has already listed the probable faults.
  10. If you read the post from 2009 directly above yours, he tells you what he did...………………………………..
  11. A lean condition does not necessarily mean you have a bad sensor, more likely you have a small vacuum leak or an overly lean cylinder somewhere on that bank, leading to the lean conditions the sensor behind the cat is seeing. A smoke test and reading the spark plug colors should help sort out the problem source.
  12. Worked for me, but perhaps you need to be a contributing member to see it...………...
  13. Audi and VW use them. Amazon was selling them at one point.
  14. Put the car on an alignment rack, it one is bent, the car will be way out of alignment, and which way it is out will tell you were it is.
  15. I find your comment that oil cooler leaks are common rather odd as we have only seen perhaps six leak over decades of working on hundreds of these cars, and most of those leaks were on Boxsters. What kind of leakage are you experiencing? Coolant or oil? Intermix?
  16. Could be, but you need to confirm the lean misfire theory first by looking at the plugs.
  17. Lean misfires are air leak related (excess air getting into the intake system).
  18. The immobilizer can look clean and still be problematic (cold solder joint, etc.), which requires special equipment to evaluate it. I would go back to the dealer and inquire how they determined the problem, it could still be real. Another possibility is the ignition switch electrical section which is a well known failure point on these cars.
  19. Welcome to RennTech Could be a lean misfire, I'd pull a plug or two, looking to see of they are overly white, sign of lean condition.
  20. Welcome to RennTech Wet immobilizers are a common every day problem with the 986/987/996 cars. You may be able to save yours by having someone like the ECU Doctors have a look at it; otherwise you are limited to trying to find the immobilizer, DME, keys, ignition, and door locks that all match from another car. Either way, it is going to cost...……….
  21. Doesn't matter; if they pulled the car up by one of the tie rods, you probably need a new one as it is probably slightly bent, and a front end alignment. Tow hooks exists for a reason...……………….
  22. NEVER do that. Get a bigger torque wrench, which has a longer handle for just this reason. Increasing the leverage on a torque wrench can seriously damage it and will throw it out of accuracy.
