There was only a small amount of oil in the coolant that I drained not at all a concerning amountĪs mentioned on several occasions I'm trying to fix the problem before it gets worse I drained the coolant today and flushed the system through with clean water before refilling with fresh coolant. It very well may have done the job and been a quick temporary fix to help me isolate the problem.
I decided to give "Holt's Radweld Plus" a go this week to see if it would seal up the leak. I've also been trying to work out if I could have accidentally introduced oil into the system myself by accident. I can't think otherwise what it could be to be honest. It's very hard to tell if it's actually engine oil. I have already fished out some "oil" with my finger. Still making up my mind what I want to do but welcome any more suggestions. They quoted me over £250 for the same part but said they'd happily allow me to supply it. I have called up an independent garage and got a quote for £39 for diagnostics and £119 for labour fitting a new oil cooler, which I would supply myself as I can get it for just £50 from Eurocarparts. Obviously I won't be taking them up on that offer. Quick update: I called Audi this morning and got a quote for £320 for diagnostics. Not sure of how much this might help pending other replies.Ĭan you extract the oil? Using a srynge or similar, so you can check that it is indeed oil. If this oil was entering the coolant via this gasket, then there has to be the start of a failure between the oil gallery and an adjacent waterway. It can also protect links between (high) oil pressure and usually (the lower pressure) the coolant channels. There are a lot of misconceptions about head gasket failures, since this gasket protects not only combustion pressure to combustion pressure, but this pressure to a coolant channel or the oil way.
possible point under "My thoughts" in this case. If anyone has any ideas or thoughts please let me know!ĬIn the absence of any other replies to date, I would be tending to follow your 3rd. I'm not even certain it is oil if anyone has any other guesses, but I am fairly sure it is. My guess is either the oil cooler has a tiny fracture or there is a leak in the rubber oil cooler gasket

I believe if the head gasket had cracked I would not still be able to drive the car Wherever this leak is it has to be astoundingly tiny I first noticed this issue about three months ago and it's seemingly not gotten worse There are absolutely no signs there is anything wrong with the car and no performance issues There is no sign of any moisture entering the oil system whatsoever, no froth, sludge, nothing When running the car with the expansion tank open there are no bubbles indicating there are no exhaust gasses escaping into the cooling system The car is not loosing any noticeable amount of oil or coolant at this point The oil is not mixing with the coolant, there coolant otherwise is fresh and clean There is less than a 10p coin size amount of oil floating on the surface There is a tiny amount of oil floating on the top of the coolant in my expansion tank I have had the issue for about two to three months, but I haven't used the car a lot in that time. I have provided details below and done a lot of testing and thinking on the matter.
I really hope someone can help! I have a tiny amount of oil making it's way into my cooling system. I'm having some issues with my Audi A3 2.0 TDI Quattro.
