Old ecu burnt and my mechanic ask me to change the ECU (PND33820)but when i connect the new ecu car wont start bt crank and Security comes up.
My question is, Do i need to reprogramm it ; please help me
What year is the vehicle?Did you reset the alarm system bec if not it won't start either, plus most of the newer vehicles do require the dealership to reprogram the comp system.
