The battery died, so i replaced it and the car would not start. Everything else works. Dealer said the Computer was fried due to battery being hooked up backwards, which it was not. Wants to charge 2400$ to fix and says the new computer might not recognize the wiring harness, which would be 6000$ to fix. My question is about the "computer". Is that the ecu and can i get another and flash it to my car, or do i have to get the one he wants to order from "Germany that is programmed specific to my car". Also, shouldn't the computer be smart enough to protect itself from something like that, inline fuse or something. I just need to know the truth before I let him bamboozle me into 6g's. Thanks.
