An "ABS like noise" coming from the well behind the driver seat indicates that TCS was trying to enable brake intervention.
Maybe the TCS switch is defective. When he turned TCS off, was the "Traction Control Off" light on and was the tech getting the vibration feeback though the accelerator pedal one gets when TCS enables? If not, it might be that even though he pushed the switch, TCS was still enabled.
There is an easy way for you to test this.
Find a wet road or wet parking lot. Turn TCS off, then try and spin the tires. You should be able to do that easily. If TCS is on, you won't be able to spin the tires. You will feel the accelerator shaking and the rear brakes enabling.
