Hello friends first post on here.

I have a 3.0 signum diesel and the radiator fans wont stop even when the engine is off and the car is locked then run until the battery dies.

I have had the diagnostics on and the got the three codes

p1481
p1482
p1483

they say the fan control circuit 1, 2, & 3 low voltage,

iv been on to vauxhall and a new ecu is £110+vat.
Has anyone else changed this ecu and did it fix it, as i see a few people have had the same problem

regards
