  1. P0446 is the code for a blocked EVAP system purge valve P1124 and 1126 indicates the system is so lean that the DME cannot correct for it, usually a sign of a vacuum leak in the intake system; none of these codes have anything to di with the O2 sensors..........
  2. P1530 - No triggering of the actuator, in the active position Possible faults: -Short to ground -Actuator defective P1531 - Trigger of actuator, no active position Possible faults: -Open circuit -Actuator defective Diagnostics: P1530 check triggering wire for short to ground, if none is found, replace actuator P1531 Check for battery power on supply wire, if ok, check triggering wire for continuity; if both ok, replace actuator Because the car has been sitting, I would look closely at the condition of the wiring harnesses.....................
  3. All depends, did the PPI include a full road test of the vehicle? If it only included a lift inspection, probably not.
  4. I would start looking at the drive line: wheel bearing hubs, axle shafts, etc. If the engine had a balance problem, it would shake revving it in neutral; if that isn't the case, the drive line is all that is left. 😉
  5. If codes will not clear, that means the fault still exists and needs to be repaired for the code(s) to clear. 😉
  6. Foxwell, Autel, and many others have persistently offered "Porsche" specific models, "BMW" models, "Merecedes" models. etc., with claimed "factory level" diagnostics that always seem to turn out to be "available in a future subscription update" that never seems to materialize. We have had salespeople bring their hardware into the shop for years, and we have always sent them packing because it never could do what is needed almost every day in the shop. If you want factory level diagnostic capabilities, "you gets what you pays for............." And Loren is correct, gateways are not prone to fail without a reason
  7. You have an alarm fault as witnessed by the double beep. With a Porsche specific scan tool (PIWIS or Durametric) you can read the last 10 recorded alarm faults, which would point you to exactly where to look. 😉
  8. Welcome to RennTech Year and model of the vehicle would be useful, as would the type of diagnostic tool you are reading the codes with...............
  9. Your vehicle should carry the 7DT75 model gear box, which is only used in the Panamera, and the filter listed in your invoice is for a filter for the 7DT70, which is a non-Panamera model PDK which has multiple oil circuits that the 7DT75 does not have. I do not know if that makes a difference or not, but it caught my eye.
  10. Welcome to RennTech I don't know where you took the vehicle for PDK service, but there are a few things you need to know about these transmissions: These tran's are extremely sensitive to the type of fluids being used (see my post above). To service them correctly, the shop must use a PIWIS unit to complete the service process as no other diagnostic tool can correctly access the systems internally. There is very little parts availability for these gearboxes as Porsche never intended them to be disassembled for service in the field but replaced them with rebuilt units when problems arise. Aftermarket parts are questionable at best, potentially dangerous in the worst-case scenarios. Ideally, you should take the vehicle to a Porsche dealer and have them check it out for you.
  11. Smoke test it, that will save you hours of chasing your tail needlessly........
  12. Are the metal shavings in the paper towel ferrous (can be picked up by a magnet)? It is not unusual to find some sealant materials in the oil pick up, but you have a lot which can cause oiling problems, and I would be concerned about the fine black debris in the oil sump cover and on the oil plug. Fortunately, the oil filter does not look that bad, but I would think that further investigation at a minimum is required.
  13. Welcome to RennTech Try posting your request in the correct forum thread, and you will get an answer: "Lost Radio Code - post your request here"
  14. The service manual says: "Side-airbag sensor (sensor for airbag) Fault codes 85, 87" "1. There is an open circuit in the wire to the sensor. 2. There is a short to ground / voltage between pin 3 (sensor for airbag) and control module pin 20 or pin 21 3. The sensor or control module is faulty. Check wire to the sensor for open circuit / leakage resistance. If no fault is detected in the wire, replace sensor"
  15. Never said it was fun. When you are done, replace the bolts with appropriate sized stainless steel Allen head screws, use SS lock washers and brass nuts to reattach the header; the brass nuts are sacrificial and can be thrown away after use, but the SS screws will stay like new forever.😉
  16. You still have the misfire, and it is impacting the O2 sensor on the same bank.
  17. If you ran it without the MAF connected, the engine should idle fine.
  18. It is extremely hard to read your screen shots due to the reflections, but from what I can see, the O2 sensors look like they are performing correctly. As for the misfires, you are going to need much more than the diagnostic software to trace it. The coil packs on these engines have multiple leads running to them, which would require a wiring diagram for you decipher which is which. One wire carries a 12V signal on it at all times the engine is running, another of the wires runs all the way to the DME where the DME creates a momentary ground at the moment the coil should fire; you would need a digital multimeter to check these harness wires for the correct voltage on the power lead, and a ground signal on the wiring going to the DME only when the DME creates it; if shows a ground at any other time, there is a short to ground between the coil and the DME causing it to constantly fire; if there is no short to ground, the DME MUST create a momentary ground at the correct crank rotation point for the coil to fire the plug. If that is not happening, either the wire is cut before it reaches the DME, or the DME is acting up. If all this is out of your depth, I would suggest taking the car to a qualified Porsche shop for them to have a look at it.
  19. Then you need to pull the plug on that cylinder and check it out and then start running electrical diagnostics on the cylinder in question; is the coil seeing full voltage, are there any shorts or voltage drops in the coil harness wires, is the coil seeing a firing signal, etc.
  20. Did you clear all the codes after changing the coil? If not, do so now, and then wait to see what returns, There are only a few reasons why a cylinder misfires: Coil is bad, plug is bad, coil is not getting power or firing signal from the DME.
  21. Should be in the right side of the rear hatch area.
  22. Welcome to RennTech I am not aware of another or better tool for this than the Stomski unit, particularly if trying to do the repair with the engine still in the car. It is the tool we have used when required. Good luck!
  23. You need access to the proper diagnostic tool; I would not attempt to drive the car in its current form.
