Hi. I have seen articles about changing a the after run mod thermostat switch to that of a blue type that operates at lower temperatures.
Has anyone fitted one of these as I read that it can only benefit the engine but would like to know if anyone off here has done the mod and if so is it recommended? Why did Audi not do it then?
Car is a B5 S4 (2000 year)
Thanks
