Background:

My 04 Cayenne S has been at the Porsche dealer for just over a month now.  I took it there to have a new key programmed into it. I lost my only working keyfob. I was able to copy the blade of my non-working keyfob at a local locksmith.  Well, the next day, I get a call that the computer won't take the new key and that a new sensor, immobilizer and keys were needed. Estimate: $1900.  Upset, I felt I had no choice and agreed to it.  A week later, I get a call that the parts are coming from Germany and it's be sometime next week.  As promised, a week later, the parts made it and were installed.  Computer still will not learn the factory new keys.  I'm told of numerous emails/calls to Porsche tech support over the course of another week.  The last time I called to check around the 18th, I'm told that Porsche has discovered a bug with PIWIS v3. Seems that it cannot program keys into a PIWIS v1 vehicle.  Now I'm waiting on Porsche to special deliver a working PIWIS v1 computer.  

 

My BS detector is alarming. I would like my Cayenne back, running or not, but I am at a loss on what to do.

 

Questions:

Can anyone backup the PIWIS v3 computer story?

What are the odds that my original sensor, immobilizer and key are really fine?

Should I make them reinstall my old parts and try with the PIWIS v1 computer?

The bill should go from around $1900 to $125.

 

Is there anyone at Porsche I need to make aware of the potential service problems at this dealership?

 

 

A little more on the background.  They also claim that they have a non-working PIWIS v1 and that Porsche can remote brick the PIWIS computers when a new unit is issued...??  I'm also told that the Durametric cable and software cannot program keys.

 

Any help or ideas are appreciated.

There are 3 iterations of the PIWIS Tester, and it isn't surprising to me that there are bugs in the latest PIWIS3, which was released a few months ago.  I remember cases of 9x6 instrument clusters being bricked when trying to re-code them when PIWIS2 first came out.  The PIWIS1 had a "time bomb" introduced with one of its last software updates, which caused it to stop working after a certain date.  They don't seem to have done that with PIWIS2 (yet).

I would certainly ask for the original parts to be refitted.  Why do you need new ones if the fault is with their PIWIS3 tester?

11-30 Update....Got the call today explaining what was going on.  The PIWIS v1 that Porsche sent in would not program the vehicle. Porsche had them 'send data' from a PIWIS to them to analyze.  According to the data, a control unit (955-618-602-20) and/or steering column computer (955-347-009-09) need to be replaced.  Parts + Labor = $4400.  This is in addition to the $2200 I currently owe them for the 2 remotes (955-637-944-06-0), immobilizer (955-618-036-05) and labor that were installed.  This puts the bill at $6580.

The remotes and immobilizer are not returnable because they were programmed.  The remotes I understand, because they were cut.

 

Anyone interested in a donor vehicle in the SouthEast US?

 

Just for the record, I took it to them on Oct 24 to simply program a replacement key.  36 days what a ride.....

My God I think I would be kicking off, that's nearly as much as the car is worth. 

 

I took my Audi last month in for some "extended warranty" repairs just a couple of broken lower control arm bushes. They sent me a invoice for 6400dhs about $2000. They said bushes and engine mounts need replacement (they failed to check all these items was replaced under the warranty just 11months prior, yeah great OEM quality!). 

They said because my car was "modified" intake, supercharger pulley and stage 2 tune they would not cover the warranty, really!! suspension bushes excluded. I took that as a challenge. 

Luckily the audi head technican Tyson is a fellow English man, wink, I sent him an email and didn't pay a penny to the anger of the service advisor ha ha ha.    

Sorry my story doesn't relate directly, but this goes to show the dealer takes customers for a ride if they think they can get away with it. 

 

If you didn't instruct then you don't have to pay.

The modules your mentioned are immobiliser  (kessy) with 2 keys, ECM Engine control module (dme) and steering control module. 

It sounds more likely because of their software issues they want to replace all the other modules to get around it, at your expense. What if that does not work? Crazy

      Hello Guys, 
       
      I got my 2014 Cayenne Platinum edition and it seems that the remote unlock and locking mechanism using my key fob does not work unless i am close to the vehicle, range is i would say 5 feet. 
      I tried to change the batteries on the key fob but issue still there, is there anything else i am missing or is it a design issue by Porsche that they corrected on a later versions ? 
       
      Thank you,

      Sometimes when programming the DME or Alarm control unit with the PST2 or PIWIS, you will get an error of "Test Step Aborted" followed by an error number, such as 3, 21, 25, 71 etc.
       
      I have the PST2 manuals, as well as the KTS manuals and the 986 and 996 Dealer manuals, but one thing I have not been able to find in any of them is a list of error codes that follow the "test step is aborted message"
       
      Sometimes, I have had the errors when I have put in an incorrect "old immobiiser code", or "old learning code", which kind of make sense.. But I often get the error when programming a control unit (yes I do have 14v onto the control unit and pin 60 powered up on the DME when it is a 5.2.2 DME)
       
      Has anyone ever found a list of the error codes and what they mean, or even worked out what they mean?
       
      When programming a DME 5.2.2 for example, I can often get to about 90 percent on the progress screen before it bombs out with one of these codes.
       
      The unit will still start the car etc if it bombs out, so I don't think it is a bricked DME, but I am just curious about the meaning of the error codes
       
      Anyone have any clues? or is my curiosity sending me towards a massive mission of discovery in an unwalked path? lol

      I posted this on the MacanForum, and it was suggested that I ask the very knowledgeable people over here.  I tried a search, but couldn't quite find what I was looking for.

      I'm trying to decide between the PIWIS Tester II from http://www.uobd2.net/ and the Durametric. Apparently the Durametric will not reset the electronic parking brake for service, and some have said on other Porsche forums that the PIWIS Tester II can do much more. 
      For those that know or have done research in the past, or have owned one of these, does the Piwis Tester II absolutely require up-dates to work, or just when you want to access other features? Do these Chinese products work at all?  I'm hoping it will be able adjust the level reading of the Oil Level display (mine's off, and the dealership says they can't do it), show the fill level when changing oil, as well as allow servicing the rear electronic parking brake. Since uobd2.net is a Chinese company, I'm not sure how trustworthy they are in giving accurate information about their products.

      Any one here have the PIWIS Tester II or at least tried it?  It's about 3 times more expensive than the basic Durametric, but if it can at least reliably do a few more things, I thought it might be worth it.

      Any other opinions?

      Hello All,

      Few months ago I bought PIWIS from ebay (T30 with piwis v29 installed + KTS 520) and everything seemed to be working fine so far, but I just noticed that it doesn't see all the modules in my Porsche 996. I scanned two cars with it and didn't find convertible top module in either of them, also it gives an error when trying to open ABS/PSM module.
       
      I ran a PAG plug test and I got an error saying that system didn't respond. I then did some research online and found out that the cable I had was a chinese clone, not an original .504 bosch cable. The only place where I could find a working cable was here: http://www.ebay.com/itm/181421870784?item=181421870784&viewitem=&sspagename=ADME:X:AAQ:MOTORS:1123&vxp=mtr
       
      I bought it, but it behaves the same way as the old one - PAG plug test fails, all modules work except for PSM and convertible top.
       
      Any ideas what might be an issue? Does anyone have piwis VM, installation files or KTS firmware available?
       
      Any help would be greatly appreciated.
       
      Patrick
