Thank you all for all your help. That fix the car,no more noise thank again.
You were right on, thank you very much.
Your welcome and no problem.Thank you Jo E Lefors for that helpful picture. There have been so many people in the past have a faulty Subwoofer under the seat and not know what to do. I tried to describe the best way to unhook it, but since mine doesn't have a sub I couldn't provide a picture. You solved the mystery and I'm sure there will be many more people need to see that picture in the future. DCO.
If you have a North American Smart with a subwoofer, the sub will be under the seat, above the carpet. Under the carpet is the yaw sensor (smaller “box”) and the TCM (larger “box”).A while back I posted about selling a 2008 Fortwo flood car. Everybody on here thought my car was fishy and I never got any offers and then my thread was closed by the man. Well after lots of procrastination I have decided to partner with my neighbor and repair the car. We are starting with the ECU's or similar that were under the water line of the flood. That being said we need to identify which two boxes are located under the drivers seat. Thanks for bearing with me on this project. We will bring this car back to life...with some good help.
