Recently I checked my cooler water level, and noticed that there was a layer of oil, I also checked to see if there was any water in the engine Oil, there was non. So i heard from VW, saying that it could be oil cooler, intercooler or the head gaskit.
All answers welcome.
Kind Regards

it should not be a water in oil tank it is mean engine cracked
Oil in the radiator expansion tank can be caused by a blown head gasket, which allows engine oil to mix with coolant. Another possibility is a cracked engine block or cylinder head, creating a pathway for oil to enter the cooling system. Additionally, a failing oil cooler, if equipped, can leak oil into the coolant. These issues typically indicate serious engine problems that require immediate attention.
Cracked Engine Block or blown head gasket.
you dont mix water with oil. If you have a two stroke engine it needs oil and petrol in the tank or it will just die on you. But if you have a 4 stroke you just put petrol in the tank. Hope this helps.
Front corner of the engine - passenger side, right near the radiator expansion tank and radiator cap.
tank top in the engine room
Oil in the expansion tank indicates a leak between the internal oil channels and water channels within the cylinder head. This is usually attributed to a failed cylinder head gasket, cracked cylinder head or cracked oil cooler (where fitted).
The most likely cause of this is a leaking or failed head gasket,with the engine running,see if there is excessive pressure reaching the header tank,also examine your oil dipstick,and an emulsified oil level (a creamy consistency),indicates also a failed head gasket,if you are not sure,take it to your nearest garage for a check to be carried out.
if there is a mayo like substance in the oil/water which is basicaly oil in water or water in oil, or the system is pressurising (water coming out from the expansion tank) also exessive white smoke coming from the exhaust (water entering the cylinder) if its pressurising or overheating replace the thermostat & expansion tank cap first as the cheapest option, if its mixing or burning water its atleast a head gasket (possable head skim) hope this helps
The oil pump moves the oil from the tank through the engine and filter and returns it to the tank the way the heart circulates blood.
there is no need for an engine oil drain plug, because when the oil filter is removed and the oil is drained from the oil tank (by way of the oil tank drain hose located by/under the battery box) there is no oil that remains in the engine.
The engine oil sits in an oil pan that is bolted to the bottom of the engine block.
