I agree on the trail. Threads like these will be useful.

The KESSY will look for the ELV as they are part of the security of the car. I think it just looks for it but not sending any instructions. They confims if both party has the same ViN. That’s the reason why the chip needed to be transferred to the emulator. It contains the ROM that stores the VIN. New column which includes a whole new ELV needs to be coded to the car. Apparently it’s a 1 time thing.

one thing I wanted to try was to see if I could change the fake unlock sound by the emulator to something cooler. Haha.don’t have the time for it.

 

Hopefully this thread is stil alive, I have an 04 Cayenne SI am trying to help a client with. He's a great guy, he is 90 years old. He just put a 71k mile replacement motor in the car in January as well as new cats and the wiring under the passenger side was corrected and then shortly after had a oem driver side headlight installed. Thus far he has paid 17,400 dollars in repairs to a 7k dollar cayenne S. My objective is to help him for free. I have done the unplug and plug back in trick, no luck. I have a durametric enthusiast for my 964's but the key doesn't power anything on. I've done the break hold, as well as the flashers and brights. Durametric shows as scanning. And light just blinks when its plugged in. I did read somewhere else that there is a fuse or module to send power to postentially to power up the system to scan codes. I think that is my next step. Can anyone tell me what im looking for and how to do it? Also a few other questions 1. do you leave the drivers side door open? Do you plug in durametric after you hold the brake or prior and let it search the whole time. Do you hold the break and let the hazards go as it scans? The order of operations seems to be all over the place. Vehicle is an 04 Cayene S (US LHD) milage on Odometer is 174995. Thanks in advance.

 

Durametric used to have a glitch that required a very specific connection sequence in the mid-2000s year vehicles. First, make sure your Durametric software and drivers are the latest version, then follow this sequence.

1. boot the PC fully
2. Without the OBD2 side connected, plug the USB end of the cable into the PC, wait for it to complete the add new hardware wizard it that pops up
3. At the Cayenne, then the ignition key to the full accessory position with all the dash lights on and the PCM powered up ( you can turn off the PCM and HVAC if you want).
4. Turn on the hazard lights
5. Open the Durametric Software on the PC
6. Now plug the OBD2 port end of that cable into the car
7. From the Durametric pop-up menu select the generation and model of the vehicle you've connected to and click the next or ok box or whatever it says
8. The next box should pop open and should show the engine type of the vehicle you're connected to automatically and the bottom of the screen should show connected

Let me know if that works for you.

 

I had all the same issue you are discussing now. I put a new battery in and reset the codes with my Durametric and all was done. If the client let the battery get low and he tried to start it that is what most likely caused the issues. As far as what to do with the Durametric: If you have the current program you should not need to do anything. My works with door open closed whatever. But if you are in the middle of a "session" and it get disconnected: Turn key-cable loose, etc it will freeze up and you need to restart computer. The hazard light stuff as some say the Car computer will go into sleep mode- that keeps it alive. I have never had the issue with either my 955 Turbo or 996.2.

But I would start with good 13 V plus power. These Porsches are very power sensitive wise. I also now keep it on a charger if I know I will not be driving within a week. Good Luck.

 

Thank you for your time I really appreciate it. I did get a little further but when it comes to selecting the cayenne model it then brings me to a box that says connection is in process and another that says cable is not ready. And status shows “device is not powered on, make sure cable is plugged into the car and the key is the ON position” I’ll attach a photo for reference.

 

i will order a battery thank you for the reply, it’s appreciated.

 

When you first.plug the USB into the PC, does it show cable connected.innthr bottom left.corner, does the PC dong likenitnknows you just plugged something in?

Might try to delete the drivers and reinstall the latest versions

 

yes show device is plugged in.

 

Know anyone else with a similar car where you can test the cable and PC on theirs to see if it works, which would tell you if it's the hardware or the vehicle.

 

Test it on a non Porsche or you'll burn one of your VIN's.

 

Good point - forgot he had the Enthusiast version.

 

Last week I got the steering faulty on the dash in my 2009 Cayenne GTS with 111k up to this point I’ve had no issues with the truck.

I checked the battery and it had a Iow reading so I replaced the battery with a new one.

I rented the durametric tool on eBay and the first time I cleared the fault it started I got it from infront of my sisters house back home in the garage.

I read all the forum posts regarding the steering fault code and started looking for water. Yes, there was an unbelievable amount of water under the carpet on both foot weels. I pulled the carpet up and soaked up the water with towels and used a portable heater to dry up the foam.

I pulled apart the looms on both sides to check for corrosion. I couldn’t see any immediate signs of corrosion. I pulled apart the 3 factory splices. The black ground, the brown and red and the red and yelllow. I used soder, liquid electrical tape and heat shrink.

In retrospect I should of checked the fuse box first on both sides because when I did I realized that on both sides the 2 bottom rows of fuses arnt getting power. Using a pen light it shows no power when the battery is connected and it’s in the accessory position. Rerember the car won’t start. I also noticed that fuse 26 on left side a 10 amp that controls the ECU etc is not getting power.

Can you guys lend some assistance?

ps. This is my first attempt at a DIY

Thanks

 

I use the cable on my 964s occasionally and it works fine. Cable blinks and shows as connected until I click on the 04 cayenne and it brings me to the next menu. I will double check on my 964 but it should be fine.

 

Drivers deleted and redownloaded! Thanks for the tip. This car will be the bane of my existence.

 

Not sure I understand what you mean. I will google. Didn’t know by plugging in I could mess something up. I do have a Snap On system as well as a generic one for certain makes that are not supported by Snap Ons Computer.
