Hi guys , hope someone have a clue on what happening with my car
Sometimes the cooling fan won't stop, and others it just blow for few seconds as i turn on the ignition, and sometimes it just work fine, also have a message ''Car service necessary'' pop out with the strange behavior of the Fan ???
the car is a 2012 1.6 turbo with just over 30000 miles on it.
Thanks for help

Could this be related to the thermostat wiring harness issue they had?

It is a 1.6 Petrol Auto
