    sounds like it will be the radiator fan switch (£10 part), or possibly the engine temp sendor switch (£10)

    Is your air con always on? Air con being on starts the fans immediately.

    no air con is off very rarely use it to be honest, the fans just come on straight away and then you can lock the car up and go back out in say an hour and there still be running so i have to pull the fuse out to stop them

    OK, fair enough. Best to check the obvious things first.

    It is likely (99%) to be one of the two coolant switches.

    Firstly, you say the car runs at 80ish deg C on the dash which isn't right.

    VAG COM scan would help and most likely identify the problem - however it pretty likely to be one of the two sensors. Change them both. All will be well.

    Could be, and is the more likely.... BUT since you have a new CTS to use already, I'd start with that.
