Hi everyone
I have a 2010 mk6 golf, 1.2TSI. It has a fault, when diagnosed comes back with P128F which I believe is a coolant temperature outlet sensor malfunction
I have replaced the sensor on the bottom right hand side of the radiator (I think it's attached to a hose) however the problem still remains.
Is there another sensor? If so where would this be located please
Thanks for your help
