Traction control, engine management light have come
On and cruise light flashing. 
Anyone any ideas what issue maybe, got an Impreza WRX 2.5T hatch 2009.

need to get it plugged in to find out the fault code, i;d drive it as little as possible and if you do have to drive it very very gently and low revs and no boost

As said above mate. Will need to get the codes from the ecu. There is apps about now with Bluetooth obd2 reader's that can do it handy little device but be better getting a garage to do it with proper equipment.
