Hi looking for help, got a 2013 Fiesta ST180, it was recalled to Ford last week with a coolant issue, they replaced Header tank and more, got car back and since then sometimes on acceleration the spanner light comes on and dash say Engine Service Now and loss of power/turbo but still runs!! Was running and driving fine till went into Ford for Recall, took back today and they done a reset and said it wont be connected to the work done on the recall, however told them nothing like this was wrong before. Any ideas?????
