Review: Did the trick. - With the engine warning light coming on periodically, (following an OBD2 scan) it became clear that I was having problems with my catalytic converter. After fitting this device to the downstream O2 sensor the engine warning light stayed off, (and with the use of a catalytic cleaner) allowed me to pass the MoT test. Well worth the money !
