  1. I was at dealer ans saw, what he did, VIN from donor is requirement to get radio work on new vehicle. Also, before I went to dealer I contacted to online services to get unlock code and they do specifically ask for VIN from donor vehicle, it requirement. When radio first installed on the car and car is turned one, it assigned VIN and generated security code and get that code to non volatile memory, built on the board in side that radio. The code will stay they forever, until dealer assigned new security code.When car is started, the PCM module is checking the radio security code and compared to VIN on new car,and then you radio start working.If the security code is not there or it not matching your VIN, radio do not work at all.

    In conclusion, to generate new security code, donor VIN required, so the old security code, based on old VIN and associated with old vehicle can be deleted. Also, donor VIN, required to update a sales code on the dealer database.

  2. The injectors do indeed make a clicking noise that is audible with a mechanic's stethoscope, and that is a good way of verifying an injector is not dead, but that noise is not normally audible while the engine is running, and I doubt that is what you hear without the stethoscope. Valve noise is more common; if that is what you are hearing it will become much louder then you take the oil filler cap loose (be aware oil may splatter when you do that). Exhaust leaks around the manifold gasket make a surprisingly metallic sound that typically is loudest when cold and quiets down when the manifold warms up but from what you have said I don't think that is your sound - I think it is valve lash or (if you have hydraulic lifters) a collapsed lifter.

    Clicking or ticking sounds from fuel injectors is normal. Most likely the fuel system cleaner has removed some gunk and varnish from the fuel system that was providing some "cushioning" to the injectors and quieting them slightly.

    There's nothing that you can do to make it go away. As long as the engine is running normally and the ECU isn't throwing an error code there's nothing to fix. Arguably you could replace the injectors and any rubber components of the fuel delivery system and that might lessen the noise level slightly but the cost would far outweigh any benefit.

  3. At least all this modifications, do not void warranty:"NON-FCA MODIFICATIONS

    The warranties in this booklet do not cover repairs required because of non-FCA modifications,
    installation of special equipment or accessories, or use of special materials, fuels or additives. This
