anyone would advise the cost of replacing the oxygen sensors before our cat for PreFL E90? as got an error code for this. heard that this will be coming in a set of two sensors together.

Re: replacing oxygen sensors

yes.. there is total 4 sensors, 2 before & 2 after.. Best is change all the 4 together to save your labour charges.. cos the norm is when 2 spoil, the other 2 is also about time.. I check with the boleh land ws, the labour to replace 4 is about rm300.. the 4 sensors will cost about $740..
