Can anyone help me or suggest someone who is able
to replace serial number in this dump. It is visible in ASC format,but is also crypted.
I am doing some experiment of teaching used ECU on this car.

IIRC EDC17C66 is a Peugeot engine, so it might have, but MB usually does not have OTP.

It doesnt have for sure because i have already cloned this type of ECU EDC17C66 used in MB W447 with KTAG.
