Pre Cat O2 Sensors

Post by Bi11 » Sat 31 May, 2014 19:08

I have error code P0154, which from internet searches is the pre cat 02 sensor. I will book it in for repair, but at 59,000 miles is it as well just to get the 2 sensors replaced rather than wasting time looking for dodgy connections etc first?
