Need immediate help. 2000 1.8 turbo new beetle. Car turns

Customer Question

Need immediate help. 2000 1.8 turbo new beetle. Car turns over, will not start. The problem is NO CHECK ENGINE LIGHT at start up, not allowing car to start. Replaced ecu with used (programmed) unit. Still nothing. Continue to show codes 0725 1780 1850. Fuses and relays are good. Is there something I need to do to pair new ecu with car. something is keeping ecu from showing up on start up. Thanks for the help

Thanks for choosing Just Answer .
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.
