Amablemiguel! I don't think the problem with PSM error is there because of weak battery or broken ABS sensors. At least in my case (and in all other cases I came across) the problem was due to impossibility of the new stearing wheel position sensor to communicate with ABS module of the car properly. My simptoms were exactly like yours - sometimes the error came, sometimes it was gone after few hundreds meters of the car movement... My problem was fixed only by hacking of the software of ABS module done by the Russian technicians (Serg124 mentioned this few pages above). And it was done not by PIWIS.

Airbus Driver! Error free retrofitting of the new stearing wheel is possible. Probably (depending on the other components in your car) you will need to hack your ABS module software. If I were you I would wait with retrofitting until Amablemiguel is done. Completely done. But you can go ahead with buying the parts...

 

I ran the new steering wheel with everything else unchanged. No errors just multifunction buttons not working. So is it the new lever unit or clock Spring which is failing to communicate with the ABS module rather than the new wheel?

 

Gtrust, what do you mean by "everything else unchanged"?

Firstly, the wiring shall be changed in accordance with the diagram posted in that thread. Secondly, the new components shall be adopted by PIWIS. After that all functions (multifunction buttons and gearbox paddles) of the new stearing wheel shall work.

Then, depending on your particular car version of software, PSM error may arise (that was my case). Which can be fixed, as far as I know, only by hacking of the ABS control unit software.

And yes, clock spring unit (to be more precise, the stearing wheel position sensor in it) fails to communicate with ABS module without software modification in the last.

 

I get what Airbus Driver says. I get what YOU say. In my case PIWIS 3 says i have a broken ABS sensor. Again i still need to change my rear sensors. Keep in mind that if you install the wheel the paddle shifters do work without the need to code anything. Only the MF buttons will not work. There is no way he managed to just put the wheel and magically it's all working. New clocksprings needs CODING.

I perfectly understand that it could be a the communication error. I was told that at the beggining by Serg124 but i must follow the PIWIS 3 errors found. At that moment when we finished the installation we coded, we cleared everything. 3 days later PSM came on, i went to the shop with the intermitent error and got that an ABS wheel sensor was broken.

Now if its the module, could installing the most recent MODULE fix the problem? lets say 2015-2016 Cayenne ABS Module?

Listening to anyones thoughts.

 

NN I meant I bought the wheel and put it on the car without doing anything else. Everything was ok except the multifunction buttons didn't work, no PSM failure.

I have all the bit now to do the proper conversion but I'm hesitant if you still get a PSM failure.

My car went in to have the work done but the tech got scared of the liability and put it all back together again. Unfortunately I then had PSM, chassis, PDCC, stop start, and headlight control failure. They've ordered a new clock Spring to try and sort it out. After all that I'll just be back to square one!

 

yes petty much you'll get all those errors if you don't punt a corresponding Clockspring (15-16) remember you'll need the new levers BUT FOR ANY REASON DO NOT DISCARD YOUR LEVERS. You'll need to swap the high beam and an internal part.

 

This is with the old wheel back on! Everything back to original and still a dashboard full or errors

 

tell the tech to recode.. It'll take him 2 min

 

We never got as far as coding, but he has tried recoding the existing. I hope the clockspring works otherwise we have a real problem

 

There can't be an error removing the old and putting it back on. Unless he put the system on while the closkspring was off. You'll need recoding then. He should know. Again there should be no problem removing your existing components and putting them back on if no change was made whatsoever.

 

From my personal experience nothing helps, but only recording/hacking of the software of the ABS unit. And I think it doesn't matter what version of PIWIS you use 1 or 2 or 3 to check the errors.

To be honest, I didn't change ABS sensors, battery or something else... May be it could work, but I don't think so.

 

NN. How are you?

Well that's i would start by the sensors and keep discarding until a solution comes up. Again the PSM error is not constant, it doesn't bother me all the time. But today i'll change my battery, is due anyway and get on the rear ABS sensors. I can test the module step with another suv at the shop (2015-) and see what happens.

If the last resort is hacking can the module be shipped to you or needs to be on the Cayenne?

 

Hi there, amablemiguel! I am very well. The only thing, it's around forty centigrade around here, so we are all the time either in the pool or inside the house under aircondition... What about you?

I wish you all the lack, but I doubt that the change of ABS sensors will work...

I did asked the engineer, who fixed my car, if it is possible to send the ABS unit to them to Russia to reprogram it (in case I need to change mine). He told me that they don't have the facility to do it without the car. So for the moment we only can ask them to come over for the re-programming...

And also please note that personally I have no connection/interest to that people. The only connection is that I am also Russian. And am proud of it ))))

 

Without the hack is PSM fault/disabled all the time, or does it come on and go off?

 

jejejejeje i get it... I'm Dominican... It's around 33°C now... For me is hot.. Talking on the sensor/module today no light... But I'll keep posted.
