Bought a bluetooth ODBII fault code reader from EBay and dowloaded the Torque lite app from the Google play store to my phone. Plugged the reader in and it worked a treat... read the code and I could clear off the EML. What a bargain for £2.99..!

Anyway it gave the code P0141 which I think is the O2 sensor under the car on the exhaust. Is this correct? Looks an easy DIY fix - is it?

It's a fault code for the heater circuit to sensor 2 (downstream of cat).
Either there's a wiring fault or the heater in the downstream sensor is burned out.
Downstream sensors are usually very easy to get to, but not always easy to unscrew.
Make sure you get the correct sensor with connector, not a universal sensor that you're supposed to splice wires to.
