    Decoding an engine VIN

    In no way do the VIN numbers and engine numbers match on a Porsche. About the only way to find out if the engine is original to the car is to order a Certificate of Authenticity from Porsche with the VIN. That should list the original engine number.

  3. The OBDII codes are indicating an intake air leak or vacuum leak, resulting in misfires P0300-P0303, P1316...probably. Since you have already replaced the O2 sensors and MAF sensor you can rule those out. It could be coils/plugs, but all at once and on Bank 1 and cylinder 4? Does not seem likely. How old are your coil packs and plugs? First rule of mechanics...always go back to the last thing you did. AOS replacement is a huge job requiring removal of a lot of things. Suggesting it may be something left unplugged or not reconnected right during the job. Sounds like you had a shop do the AOS replacement. Could you take it back to them for diagnoses of the current problems? Did you check the oil filler pipe? It has to be contorted many times out of the way during AOS replacement.

  5. A lot of top engine stuff needs to come out to replace the AOS. I would first check carefully the oil filler pipe for cracks. It usually cracks where the corrugated section starts. Make sure the oil cap is on tight. Since the front and back intake plenums are removed during AOS replacement, check the plenums for centering and all the clamps are tight. Then you need to start checking the vacuum lines, and there are a lot. You might need to smoke test the vacuum system and intake system. A lot of times someone forgets to reconnect the vacuum lines, particularly the one to the resonance flap on rear crossover plenum, and the other ones (two) to the back of the front plenum. vacuum lines.pdf
  6. You need to check all of the drains. Run some weed whacker string down the drains to make sure they are clear.
  7. At least it stopped working with the door unlocked! If it happens when the door is locked you have a real problem.
  8. There is a pin shaft on the back side of the key cylinder that can break or fall off. You will have to remove the door card and access the back of the door handle to check it. Here is a diagram of the door handle and key cylinder. You can see the shaft on the back of the key cylinder. Door Handle WWW.AUTOATLANTA.COM
  9. Like Loren suggested, maybe an electrical issue. Check the wiring harness for the Bank 1 variocam actuator. Bank 1 is left side (drivers side) of engine, and the variocam actuator is right next to the heat shield.
  10. Your approach seems like a good one. I would do this: Drain oil and remove oil sump pan. Check oil pickup tube for debris. Change oil filter, inspect, and replace with new oil filter and get a new canister (bypass valve in the canister may be stuck open or malfunctioning). Reinstall oil sump pan then refill with new oil. Remove oil sender unit and hook up a mechanical gauge to the fitting. Check oil pressure at startup. If it is good, might be a good idea to swap out the oil pressure sender unit again. They have been known to be bad right out of the box.
  11. Rule #1 - don't take your car through the car wash! Our cars just do not like all that power spray water everywhere. Could it be that water sprayed somewhere it shouldn't have on the engine? I know those wheel cleaning jets would spray water right up on the engine. Might let the car and engine dry for a few days, clear the code and see if it comes back.
  12. 2000 MY was a transition period for Porsche. Some have dual row bearings and some have single row bearings. So you will not know until you are in there. Cam deviations depend on a lot of variables. Check out this thread And this one 996 camshaft deviations and IMS - Page 2 - Rennlist - Porsche Discussion Forums RENNLIST.COM 996 Forum - 996 camshaft deviations and IMS - Hello Everyone, I am writing again about my sons' 2000 996. I currently has 43000 miles and we have found some small brown specs in the oil filter, thanks to the members who...
  13. If both keys work to unlock the car and both keys work to start the car, then that is okay. The RFID pill in the key is passive, meaning it does not require power but is still read by the key surround to allow the car to start. At the age of our cars (close to 20 years old) and thus the age of our key fobs, more than likely the circuit board in the key(s) have given up and don't work the remote lock/unlock anymore. If you can live with using the key to manually lock/unlock the car, and don't want to fork over $400 at the dealership for a working remote key that will last for 4-5 years, then it is okay as long as both start the car.
  14. How steady are your hands? Drill a small hole in the seal, put a small sheet metal screw in and pull. Be careful to only drill into the seal. Other than that, I would try prying it out with a small flat blade screwdriver. As a last resort, you may have to pull the brake piston out and then pull the seal. You will lose a bit of brake fluid and you will have to bleed that caliper once done.
