Coolant leak into oil

its in your owners manual and on cover of fuse/relay covers https://www.manualslib.com/manual/396576/Audi-A4.html

Sounds like a cracked piston ring to me. If you didn't do a re-ring when the head and turbo work was done, you probably should have. Now it may be too late.

Engine oil capacity with oil filter replacement = 6.0 litres.

Please do rate my response. Thanks!

check your engine oil. if you see any coolant or water in the oil then most likely your engine gasket is burnt. I hope this helps

no. suspend engine with engine brace and lower suspension.

hi did you get a solution for this? the same thing happened to me too.I had my oil change yesterday and today I saw the engine oil pressure lights come off and the oil started leaking very bad and the mechanic told me that the oil filter housing cracked.

Check the coolant temperature sensor housing in back of the engine. This is made out of plastic on some model years A4 and eventually leaks coolant.

I have an A4 quattro 2003 and have the same problem. Found hose at the top end of engine at the back close to the battery housing was leaking. Terribly awkward job to replace , been quoted £200.

Could be thermostat this regulates the water flow around the engine to keep it cool sounds like it is sticking open when water gets hot!!

I hope that you had the proper weight oil installed, at your oil change. If your oil is up to the proper level, and it's rattling ,this is VERY bad. White smoke usually means steam in the exhaust, and that means a blown head gasket. Check your coolant level. I wouldn't drive it anymore......until someone knowledgeable can diagnose it!!!!!
