Yellow Engine warning light
last year my 54 plate MCS engine emissions light came on for a week or so, then went out. It continued to come on/go off for a couple of months with no other problems with power, consumption etc etc. I mentioned it to the garage when it went in for its service in November. They cleaned up the connection to the sensor and it was fine for a while, but has come back again. Does anyone know exactly where it is, or can provide a picture please? I,d like to take a look at it myself, maybe even change the sensor if its easy enough to do.
