If you get the full expension tank of mix oil and water and white ''mayo'' in the engine first !!! Replace oil cooler !! Don't believe if someone says : Head gasket or even : Engine block gone. The only problem is to clear off this oil from cooling system. Best way to replace set of hose and new tank.
It is not hard to replace the oil cooler of your Audi A4, but it is advisable, however, to get it done from a professional mechanic instead of attempting to replace it yourself. The head of the oil cooler must be removed and the gasket must be checked. It must be ensured that the head and the block of the oil cooler check out without any warping.
Most mechanics will tell you that the oil cooler is likely to be the culprit since there could either be a problem in the block or the oil which originates in the oil cooler may be mixed with water. The chances of the engine block introducing oil into the coolant are not very bright. Oil coolers do undergo a lot of wear and tear. It may be a slight problem to obtain a replacement for your oil cooler at your local automobile parts store, as it is unlikely that any replacements are being manufactured. However, if you are fortunate to get a new one, do take it to a mechanic rather than replacing it yourself.
