hi guys got a toyota avensis in with p0420 cat efficency stored scoping both oxygen sensors confirms faulty cat normally a straight forward fix, however custumer has been told by dealers that the ecu also needs to be replaced. After a bit of searching on the net i have found the technical service bullitin from toyota has anyone had any experiance just fitting a cat an sensors as changing the ecu seems a bit severe thanks lee
