  1. Massive wear edge on rotor can cut into new pad and then into wear sensor. I only use OEM brake pads as I think they have the best overall braking performance.
  2. Have you checked the fuel pumps for volume and operating pressure? Sometimes misfire codes can lead you down the garden path, you have misfire codes for certain cylinders but it might actually be the paired cylinder at fault. Example would be a four cylinder engine with firing order of 1-3-4-2. Cylinder 1 and 4 are common to each other as is 3 and 2. Engine fault code P0304 but actually cylinder #1 is at fault..... just something to be aware of. Also carefully inspect the ground path and wiring harness for the coils on the bank in question. Age/Heat can deteriorate the harness and cause issues
  3. Replace the EVAP purge valve located on the drivers side of the engine (left), it has a long plastic tube that runs along the valve cover and connects at the throttle body. It often causes an intermittent vacuum leak and draws in hydrocarbons from the charcoal canister tank. The part has been updated and only takes a few minutes to change out.
  4. The locking mechanism that engages the steering wheel lock fails which is controlled via a module operating a small electrical motor which is all part of the steering column. A new unit must be installed and coded by a OPC or someone with the correct scan tool/software. I've tried to install used units with no success. Porsche isn't the only manufacturer with systems like this, it's the norm these days and many other makers have many more problems with their hardware than Porsche.
  5. Have the freon level checked, unfortunately you need to measure the recovered amount to know if it's low or not.
  6. I have reset the reminders early on my vehicles without issue several times. The only problem I've ever encountered is with the laptop not being plugged into the mains, they slow down just running on battery and sometimes it doesn't reset in the Cayennes.
  7. I'd start by checking every electrical connection near where the work was completed and make sure it's all seated correctly.
  8. The only thing I'd like to add is in regards to the engine stall, have you cleaned the throttle body and reset the throttle body adaption after a cleaning?
  9. Sounds like a battery fault. How did you test the battery to determine it's good? The early production first generation had a problem with the alternator cable, your vehicle doesn't suffer from that issue.
  10. PCM is just a head unit, it will have all the buttons but you need the corresponding modules much as phone, nav, sat radio for it to function.
  11. Check fuses then inspect the wiring to the sensor, if everything seems in order replace the sensor.
  12. You'll need to return to the garage that completed the repair. I'll guess your assumptions are correct and they've wired it incorrectly.
  13. What spark plugs were installed? Maybe it's just a matter of a cold fouled plug? Where they torqued correctly?
  14. Friend has a 2005 Cab and something came loose inside the muffler and caused a rattle- had to replace the muffler.
  15. I'm wondering if anyone with a 993 that was originally bought in Canada can send me a pic of the compliance decal located on the drivers B pillar. Dimensions of the decal would also be appreciated. Thanks.
  16. Front lower control arm big end bushings? You need to have it inspect as this is all guess work.
  17. Remove the electrical connection and see if it has oil in it. No oil= no problem.
  18. Nothing to lube but you'll need to closely inspect all of the drive accessories again with special attention to the water pump.
  19. Mounts will reduce the vibration transmitted but not stop the actual idle control fault which is causing the shudder in the first place.
  20. Properly installed is the key. I've had many times an after market audio unit wired in improperly and stopped communications with a scan tool and have read of cases were it has damaged the scan tool. Some OBD cable are even fused to protect the scan tool.
  21. A lot of the Durametric problems with the Cayenne line has to do with the use of Siemens made DME's in those models, which apparently use a different diagnostic logic. From what I have read, VW diagnostic systems, which do not work on other Porsches, seem to do a better job with these cars. I was informed by Durametric not to use VW diagnostics ( such as Ross-tech )on the Cayenne as it can cause CANBUS faults.
  22. It's probably the starter bendix bushing making the noise, have the unit rebuilt or replaced. I've never seen the starter outright fail over this fault just make noise.
  23. Any after market audio component? Are you having a problem with the vehicle or just this code showing up with durametric?
