Hi all

I need help, have a customer with an old Golf4 18T.
I need to write a file to the ecu, file I have, but can’t write the file?
The ECU is 0261 206 517 Bosch ME3.8.3.
I have Mpps, and chose golf 4 18t ME5.9.2 
Connected bench wires to ECU
12V –   Pin 1,3,43
Ground – Pin 2
K line Pin 19
Connected bench wires to MPPS
Pin 16 – 12V
Pin 4 – Ground
Pin 7 – K Line
With Mpps if I want to write it waking ecu, then ecu not found?
If I connect Vag com cable and open Nefmoto, I can connect to ecu, choose 29B200, Can’t write either?

Any suggestions are welcome.

Thanks
