Hi guys,
I found a problem in the reading and in the writing of the maps through the serial port with mag pro v 4,
the machine ? a audi a4 140 of 2007 during the reading of the information of the control unit,
the program gives me the following error:

The ecu is Locked, unable to continue programming,"Error - Step n: 37".

We mapped the machine several times with both mag that with mpps any problems,
do you have a solution to part of the bdm?

For case, there is a counter that stops the unit if it is written with a defined number of times?

Thanks to early
