How Long Is The PCM 2.1 Radio Code

[Jim Mavrokefalos]

I would like to replace the CDR23 on my 2005 Cayenne S with a PCM 2.1. I know that I need the PCM 2.1 radio code so that it can be programmed to the vehicle. I called the local dealer and gave them my VIN and serial number of the PCM 2.1 and they gave me a 4 digit code. When my independant connected the vehicle to a PIWIS tester and went to the section to input the code it looks like it needs a much longer code than 4 digits. Does anyone know how long (how many digits or characters) the PCM 2.1 code should be? Or do I need the 4 code digit plus another one? Any help help would be appreciated.

The code should be on your list of IPAS codes. Sorry I do not remember the length - it is a long list of codes.

Thanks Loren, unfortunatly here in Canada the dealers don't have to give you your IPAS codes (I fought 3 weeks with them just to get my immobilizer and ignition lock codes to program a key). They did give me a radio code for the PCM that I want to put in, it's 4 digits long. Is it possible that I also need the ICS/Seimens code that you were talking about in one of the other threads on this site as well as the 4 digit code that they gave me already? Thanks for the help.

I suspect so - I have only entered what was on the IPAS code sheet.

On the IPAS codes - IMHO if you own the car you are entitled to the code for your car.

Thanks again, I will have to try with the dealer again. Will let you know the outcome.

You can always try other dealers if the first one does not cooperate.

Thanks, will do.
