Hi I want to go to Super Cheap and Buy a OBD2 Reader and want one that also clears faults for a reasonable price just to have in the car on long trips. The reason being I put AD Blue in the car yesterday that I bought from Super Cheap and this caused the Amber warning light to come on I dropped into a mechanic and he checked it and it was O2 Sensor not sure if car picked up different Add Blue as Jaguar has always filled it in the past but I was told today it should not have effected the car and the mechanic said sometimes dirty fuel can cause this. So on a long trip if it came up again I can check it and clear it as do not like seeing the Amber incase it is masking a serious issue.

Thanks
