I have been able to change it to V6. PIWIS seems to report that the change was successful. However, on a restart it showed the same errors. I'm gonna give it another go with another PIWIS II setup after the new years. Been having this PDCC issue for a year now. Need my sports mode back.
Hi Richard, What I meant was that I have the exact same problem with the control unit - the fault code was "0003 - Control Unit Faulty". Can't get anymore generic than that. LOL. My repair strategy would be the same as his. The difference was that he was running PIWIS I and I tried to use a PIWIS II (friend's unit - he's an independent workshop). The replacement CU was exactly the same part number as my faulty one. Even the revision suffix is the same. I can tell that the replacement unit was made about 30 weeks later. I don't quite understand what you meant by manually coding the CU. When I go under repair & maintenance > control unit replacement, there was only option to read or write data. And as for the coding tab, it only showed 1 coding option : that is if the car is a V6, V8 or diesel variant. My car is the V6 whereas the donor unit comes from a V8. Even without able to write the data (to replace basic coding and VIN on the CU), I was able to calibrate the unit. But the errors of non-calibrated came back after a restart of the car - with the coding and VIN errors of course. This brings me to think that PIWIS II or that particular PIWIS II setup might have problems writing data. Is that possible that it is not configured correctly? I'm not particularly familiar with the PIWIS. When you get the security access code from actual values (for levelling calibration), where do you have to key it into? I did take a peek at the actual values tab, but I don't remember seeing any security access code in that page.
Hi all, I was trying to replace my PDCC control unit on my Cayenne 2008 with a used unit. Exactly the same problem discussed in this post in another forum. Also attempting the exact solution -> https://www.6speedonline.com/forums/cayenne-turbo/367160-07-ctt-pdcc-pressure-sensor-calibration.html. I read the data from the current faulty control unit with no issues. However, while trying to write the data on the replacement unit, I got the above error "65010 : Security Access Failed!". Anyone with experience with PIWIWS II that knows what that actually means? I've googled the whole day with zero hits on the description of the error.
