Without the codes, it's hard to form a useful thought. But replacing the ECU with a new one is going to cost a significant percentage of the value of the car. A used one with matching numbers would be a more reasonable choice.

 

For the best advice you should post the list of codes found, the sensors actually cleaned/replaced and the "computer" they are playing with.

Reflashing is an extreme method of troubleshooting and, if the underlying cause of the fault is still present, is unlikely to have any effect. Of all the faults we get reported on the forum, genuine module failures are a very small percentage. Unless the shop has systematically elimated all other possible causes, they could be jumping straight to the least likely.

Lots of old threads on "Dynamic Stability Control" warning - check them out. The sensor is usually OK but the wire that connects the sensor to the wiring harness is often at fault. You can replace with OEM versions or make your own if you get the connector. I think I posted on making your own a while back.
