artscot79 Posted March 30, 2013 Share Posted March 30, 2013 if its a 2013 car it will be under warranty so really you should take it back to where it was bought im assuming it is you said mk3 which is the newest ford out if its older and bought from a garage etc its covered by law for 3 months im not sure which is one or two to be honest Quote Link to comment Share on other sites More sharing options...
