    Do not double post, it is against the forum rules you agreed to when you joined.
  2. JFP in PA
    Nothing.

    Small spatula does the trick:

    Whirring. You need to check for fuel pressure and delivery rates; otherwise, you are groping in the dark..................

    This photo shows the relay panel under the driver's side foot well. The fuel pump is not normally turned on unless the engine is running, but you can remove the relay and bypass it using a simple jumper wire as shown here. Remove the fuel pump relay (shown in the inset) and then jumper pins 30 and 87 (typically labeled 3 and 5 on the relay panel). This will cause the fuel pump to turn on automatically when you turn the key in the ignition.

    Techron works with working systems, systems with old fuel problems won't be helped at all. If you do not have the testing equipment, you may be able to rent or borrow it from an auto parts store. If you are uncomfortable running the tests, find someone in your area that is and can help you. A good starting point would be to contact your local Porsche Club of America chapter and see who they recommend.

    What currently passes for gasoline these days deteriorates fairly quickly if not stabilized with an additive. That un-stabilized fuel can gum up injectors and just about everything else in the fuel system if it is allowed to sit for too long. Probably your best plan of action is to see if the fuel system is functional; to do that, you need to check both the fuel pressure and delivery rate using the test port on the fuel rail and an appropriate fuel pressure test rig.

    P1673, according to the factory OBD II diagnostic manual for your car, it a cooling fan fault at the front of the car, not the purge fan, which is P1671. If you have the Durametric system, you should be able to trigger the front fans to run and both speeds from the Durametric, might be worth checking to make sure they are both working. I would also consider getting a "second opinion" scan with another system as the Durametric indication may have the code description wrong.
  9. JFP in PA
    Just realized something while looking for resistance values: P1673 is the code for an engine cooling fan, not the engine compartment purge fan; are you sure about that P code value? The code for the purge fan should be P1671........
  10. JFP in PA
    I do not, but perhaps another board member can chime in that has done this.
  11. JFP in PA
    P1673 is thrown because the fan is not there (open circuit), you would need to find the internal resistance of a working fan and install a resistor of that rating and install that instead of the fan. The relay(s) will also need to be in place as well. An easier "out" would be to put the fan back in.

    I'd check the brake rotors for run out, you may have one or more that is slightly out.
  13. JFP in PA
    I would try running it in the driveway for a few min to see what happens; if nothing goes wrong, you should be able to drive the car a few miles gently to the shop.

    Four functions of the coolant warning light: 1. Engine coolant level too low — light flashes slowly (0.5 Hz) 2. Engine compartment temperature too high — light flashes slowly (0.5 Hz) (engine compartment blower might be faulty) 3. Engine coolant temperature too high — light is lit; pointer on the right 4. Temperature sensor at water outlet faulty — light flashes rapidly (1 Hz); pointer on the right Note The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously (1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash) __________________

    You can lease a PIWIS for around $20,000 first year and get full access to it, and Porsche was offering a subscription service called PIWIS TSI where you can license access to the information system only without leasing the PIWIS system as well. Bentley was never available electronically, only as a book.

    Welcome to RennTech The beauty of the Porsche sports exhaust system is that if you leave the vacuum connections disconnected, it is in the loud position at all times, giving you max flow. I would simply remove the wire the previous owner installed which decreases both sound and performance and enjoy the ride.............and the sound.

    Alarm systems are designed to not be easy to disconnect for obvious reasons. Get the batteries replaced and you will be back in business.
  19. JFP in PA
    Low battery output can cause the type of alarm problems you are describing. If the car was in my shop, I would load test both batteries and replace them as required. I would also do voltage drop tests across the primary battery cables for both batteries; cable condition is critical to the battery getting charged correctly and cause all sorts of weird electrical issues.
  20. JFP in PA
    Whatever you did electrically, it sounds like the fuel system needs to be recalibrated, which requires draining both sides of the tank, refilling with a specific amount of fuel, then use of the PIWIS system to recalibrate the vehicle.
  21. JFP in PA
    Jake has probably forgotten more than most of the rest of us combined know about these engines, so he is a trusted source. You would be wise doing both sides, the IMS, the RMS, new plug tubes, etc. all at the same time; you really don't want to go back in there six months down the road.............😉
  22. JFP in PA
    Nope. Because you often need to replace the actuator, to do this, you need to lock the engine at TDC, remove the cam cover, cam shafts, the chains, and then the actuator. This will require the use of cam retaining tooling, cam holding tooling, and reallocation of the cams (requiring special tooling) when putting it all back together. It would also be an excellent opportunity to replace the two cam wear pads between the camshafts as these are considered a "consumable" wear item in these engines. If it would help, Jake Raby and PCNA recently put out a video about just replacing the wear pads, but it gives you an excellent overview of the process and special tooling involved: Raby/PCNA replacement of cam wear pads on 5 chain 996

    It is the plunger assembly in the actuator, and it is a very common problem:
  24. JFP in PA
    Yes.
  25. JFP in PA
    It would depend upon what position the actuator failed in; because these are hydraulicly operated devices, a small bit of debris in the oil, which you stated you have, can jam the actuator piston in a "partial" position, which drives the system nuts. Usually, if the CPS is having issues, you get a P0336 code, but not always. The device is a simple Hall Effect sensor, so if you disconnect the harness to it, you should see 0.8 to 1K ohms between pins 1 and 2 on the sensor plug, and infinite ohms between pins 1 and 3; if either is not correct, can it and replace it with a new one.
