I have a sedan and I'm trying to replace my ECU right by the glove box. However, it has been really hard to find one that exactly match because I have been told the part numbers have to be exactly the same. Please tell me if this part is interchangeable and the end numbers can be off by two numbers?

Good morning,

No, the numbers must match exactly and it must be flashed or programmed to your car once it is installed.

Each part number represents something with your exact car. By installing the wrong one, many features may not work and the car may not run correctly at all.
