Hello I've just had my car fully serviced recently also new anti freeze as well. The radiator been fine the water level also engine oil the same as well. But recently the radiator water a tiny bit foamy or frothy. But that cleared up now in to black sludgy stuff in there. You put your finger in there its oil for sure the only thing it can be. Something recently the car was smoking black then white smelling funny. That cleared up then black, white blue smoke this cleared up to nothing. Now there no smoke at all fromt cold to hot nothing clean now all the time. But since back then the oil in the radiator problem started.
The car doesn't over heat it runs normal temp, The oil clean in the engine and on dip stick and oil cap, The radiator doesn't loose coolant. Also the car starts and runs fine hot or cold. The car doesn't smoke anymore it just normal all the time now.
The only things I can think of is the headgasket or oil cooler problem.
So I'm not sure whats happening at the moment.
Its a 306 hdi.
