Hi all,
I need a solution for check if a car have a modified ecu sw and reload the stock one.
I need that for a car buyer that need to have buyed cars with stock sw before resell them.
Car's are mainly mercedes from 2010 to recent one.
What sw is the most simple solution to archieve that ?
I can access car's with stock sw for save original programming.
I also have original mercedes ecu/obd2 solution but if the car sw is modified and signed with a version highter than the last original one is impossible to reflash to stock.

Thank's in advance,
Marco.
