    Error code "Inefficient Cat Bank 1 &2" on R230

    This code has popped up a few times and been quickly reset. Any ideas as to the cause? The only other fault likely to have been there at the same time was a temp gauge failure. It only clicks the management light on after about 5 miles and at low speed.
