Hello guys,
yesterday I was trying to read the flash of a the Siemens Simos PPD1.3 ECU from an Audi A4 B7 2.0TDI on the bench.
I was using my MPPSv16 for that, because the ECU is listed in it.

When reading with all pins connected (CAN H, CAN L, KLine) the following happened:
=> "ECU found on KLine!"
=> I klick "Read"
=> Error: "Invalid Key"

So I removed the KLine.
When reading just over CAN (CAN H, CAN L) the following happened:
=> "ECU found on CAN!"
=> I klick "Read"
=> Error: "The ECU didn't respond in time"; Something like that, I don't know the exact error anymore, something like a timeout.

I thought that maybe the IMMO makes problems.
So I connected the ECU to the car the immo is learned to and tried reading over OBD:
=> Same error like on the first try ("Invalid Key")

I used this pinout for the ecu:

The "ECU ID" Button worked perfectly, I got every information from the ecu.
Even VCDS worked fine with it, so the pinout coulnd't be wrong.

Does someone know why I couldn't read it?  Huh
I can't find much information about it...

Hello mate,

The only success I've had with this ECU is using KTAG or Magic Motorsports BDM Tool with the respective pinout. I have also received the invalid key error on multiple occasions with many tools. I hope this helps someone else -> USE BDM! Cheesy

I am here to learn and help others learn. Smiley
