Fitters...

truckman020:
all the DAFs I have driven over the years have all had ABS warning lights come on,seems to be a common fault with these vehicles,

I drive DAF CFs at a company with a fleet of over 600 trailers and it happens on just a handful, it is extremely rare to get one that does and that is including trailers that are thick end of 20 years old. It isn’t a common fault other than if you work at a company which doesn’t maintain their fleet properly.
