How do I restore/code modules back via PIWIS2. HELP !

[mjansari]

Hi I ordered a PIWIS 2 kit a couple of weeks ago.  I finally got round today to connecting it to car and having a play around for the first time and familiarising myself with the menus and functions.  Ran through all the headings 1.  Fault Memory 2.  Actual Values input signals 3.  Drive Links checks 4.  Coding Adaptations 5.  Maintenance repairs and 6. Programming.

And then I made a mistake, I was about to finish and out of curiosity I on the programming menu I selected Auto programming and ran it.    It starting running but then the installation aborted.     The cars modules seemed to have decoded itself.    The electric rear spoiler retracted and what I can assume is the cooling fans are constantly on when the car ignition or engine is switched on.   

I’ve rerun the scan but cannot see any modules on the car and I seem to have accidently wiped the modules.     I have spent the remainder of today going through every single menu/option on the PIWIS to try and recode but have had not success in recoding/programming the modules back (I don’t even have a working instrument cluster although the car engine starts and drives)

Does anyone have any advice on how I rectify this?  

 

I have a 2009 997.2

Oh boy.  Question #1: Is this a legitimate PIWIS II or an aftermarket clone?

Doubtless it is a Chinese clone. With all due respect, it just goes to show that a little knowledge is a dangerous thing.

I don't know if it will fix it, but it won't make it any worse by running the Handover Routine. Press the F7 key (Additional Menu) at the bottom of the opening diagnosis screen, and you will find the routine there. It will search through all the modules, and with luck will restore the settings. Have your VIN handy, as you will need to confirm (or enter) it at the end of the process.

I don't know if it will fix it, but it won't make it any worse by running the Handover Routine. From memory, press the (F7?) key at the bottom of the opening diagnosis screen, and you should find the routine there. It will search through all the modules, and with luck will restore the settings.

That is what I was thinking. We always encourage people to become familiar with their diagnostics tools, but not to go trying things unless the know exactly what they are getting involved with, because things like this can be the result. 

 

Some of the clones also have the ability to program, but not the programing files themselves, so starting the process kind of leaves you in the lurch.

Had this happen to me - was able to use manual coding (took two tries) then fans went off.  wad programming a rear control unit with PIWIS III clone on 2006 Boxster S.  still only have partial coding, but at least car can be driven.
