I am wondering what is involved to reset the engine management light / clear any fault codes. The EML light is permanently on.
Do I need to buy any special kit to be able to do this? I know modern cars connect to a laptop (which I have) but is there a special connector and software required? I am technical but not in the garage trade.
I am not keen on paying a Ford dealer a king's ransome for what must be a simple job. The objective is to see if Cataclean has resoved a catayst efficiency problem that I have at the moment so I may need to reset several times before I know the answer.
The car is a Ford Focus Zetec Climate 115PS TI/VCT model.
Any advice appreciated.
