Hi guys

Recently read and flash a burned REAR BCM of a Porsche Cayenne 2012 and flash D.Flash and P.Flash and worked well for a couple of days but again failed (my fault the wiring had  short close to rear left  Bose amplifier and fried the flashed one... now its finally fixed but i have a problem to flash it again...

My partnumber is 7pp907279BN and now i cant find the same partnumber with a reasonable price.... i have now 7PP907279BT used one to use..i read it can works, but i´m not sure i have to program it (first is metal crystal oscilator and the new one is ceramic type)

The question is 
- Flash only D-Flash (for immo info) and preserve P-Flash of the new one 
- Flash D-flash and Pflash and pray unit will work

Any advide will be very very wellcome

Have a nice weekend

You may have a problem.
Turn signal lights may be on
I had to program online

Hi, you mean i will have this problem if use P-Flash from original one? I decide to program only D-Flash and let original P-Flash and try, the idea is let original program or software of the "new-used" unit

I´ll try and report...

PD: No possible for me program online...

Hello there again, and to share my experience with this bcm, finally program old-original D-Flash of the BCM burned with reference number finished with BN, and let de original P-Flash of the BT reference number used one.

All start to run again as interior lights, no immo problems and work rear trunk door, but as bikej78 said may be problems with lights...turn lights no problems, but cluster said check daytime lights check...

The car actually is totally run out of battery and "electric consumtiors disconected" DTC because low battery are detected, so i will charge or replace it and again test

PD: No piwis available for me, only launch online coding is available, so if you think i have to code it "yes or yes"...any alternative will be wellcome
