PCM Issue after battery replacement

[Omega99]

Hi everyone,

 

I just recently purchased a 2014 cayenne platinum edition V6 with only 22k miles on it, it’s in mint condition.  
However, the previous owner took it to the dealer installed a new battery , and now the PCM keeps shutting off every 2-3 min . I already did a factory reset on it a few times , without any luck. The dealer wants $300 just to “diagnose “ it, they refuse to even do a simple software update. Any codes I can enter ? And how exactly? Any help is much appreciated.

 

 

Thanks

Yes, I already tried these exact reboot instructions of the PCM several times , but the issue has not been fixed and it continues to shut off randomly even when the engine is on. Any other solutions?

Just to be clear, there are two "resets" available under the Reset PCM menu:

1.Factory Settings

2.Vehicle Handover

Vehicle Handover is the one you want.

Right, I did the vehicle handover PCM reset by holding down the info button for 10 sec , and hit double yes . I did this 3-4 times now, but it still shuts off after about 3 min or so . I am thinking I have to input some type of code or do a software update somehow?

I tried to find the CD for the software update 4.76 version, but it’s sold out everywhere. Any way I can get it from someone who has it ? The pcm currently shuts off every 2-3 and it’s really frustrating, will the software update fix this problem?
