EMC warning light
 

hi Guys I realise this is prob a common as question re the EMC warning light coming on and the 6 or so problems it can relate to and
has probably been discussed to death but the one thing I can I can add to our 2010 Cooper is it came on under load returning home. We spluttered home under lose of power and parked it up. Upon restarting car is running rough and almost 3 cylinder like. Recently serviced 1000 km ago by Mini/BMW garage. Any suggestions ie oxygen sensor etc.
Thanks in advance. Merry Christmas
