Over winter, on Sweden, I asked the engineers to renew the antifreeze. Today, I checked and it was dirty black sludge deposit inside the top of the filler.
I regularly service all the other usual stuff like oil and filters etc but always asked others to do the coolant. (This time I managed to over fill the oil by about 6mm on dipstick. VP2020)
Any ideas on cause? Do I need to worry?
Thanks
