Has anyone here have had their ECUs replaced before? My 2006 3.2 V6 has been in the workshop for the past two months as it seems a replacement ECU is 'blank' and that it needs the codes in the previous ECU to be copied into PIWIS and then coded to the replacement unit. I am not able to do that as the previous ECU was practically 'fried'. My ECU is a Bosch Cartronic 022 906 032 GF. I would appreciate urgent advise from any expert brothers here.

Issue started when my 2006 3.2 V6 stalled without warning one day while I was cruising along a street. It started with hesitation for a few seconds and just died. At the same time ' PASM failure' appeared in the console. I turned the ignition off and tried to restart it but it would not crank. After a few failed tries, I got the guys at German Motors (Kuala Lumpur) to tow it to their yard. PIWIS was not able to read anything when connected, it just had this 'accessing' message which went on forever. Soon they chaps realised that the battery was draining very quickly as it constantly needed to be recharge even after replacing a new set. Eventually they found a burnt ECU. Upon opening, brown stains could be seen on the PCB and cover near the connector solder joints of the power input area. we still do not know what actually caused this burnt-out. We did find a cracked coil though and it was smoking after we connected the new ECU.

I hope to hear some advise soon. Thanks in advance.

If they have a real PIWIS they don't need the old ECU, they just need to code the new ECU to your VIN number. As in your situation, there would be many occasions where having the old ECU would be impossible, but due to theft, the ECU's are coded to the VIN of the vehicle they came out of.

Without a real PIWIS Licence they cannot get the manufacturing codes for your VIN. The fact that the ran the battery down tells me that they do not know how to use it since the first rule of PIWIS is Put the Battery on charge first.

I think they broke the ECU, never heard of an ECU frying

Thanks @hahnmgh63, @mudman2,

Is it possible for me to send the ECU somewhere for me to code (according to the VIN) and just having to plug it back into the car once its done?

Sorry but I think you will need to get it to an Authorized Porsche dealer or someone that is an authorized Porsche repair facility.
