hi i finally bought a td5 disco on a 51 plate (best i could afford!) and love it much better than the freelander or the x trail! but in all this snow my abs tc and hd lights came on last night i have searched some old threads but my question is would it just be the sensors have frozen as i was in high when i was driving and havent used hd or am i unlucky enough to have a proper fault with it? many thanks
