Hoping for a bit of advice here, just bought a td5 on a 52 plate, drove it home about 80 miles last Saturday, everything seemed great, never moved it until today, as it was cold I swithched the heaters onto hi on both sides, to be greated, with cold air only, water in header tank is fine, levels are spot on, checked the control flaps they are working, matrix pipes coming into the car were just Luke warm, bleed the system to check for air lock, now I'm puzzled, temp gauge sitting at half way on a good run ! Any ideas ? Thanks
