Oil in coolant tank.

[AndrewA6]

Hi guys

I've found thick oil inside my coolant tank.

Before I pull everything apart, I'm  after any advice as to what might be causing the issue so I can have parts at hand for doing the repair. 

 

Side notes

There is no sign of water or coolant in the oil or engine.

The oil level in the engine is good, the oil is a bit dirty and it probably needs a service but there's noe emulsion happening inside the block.

Car is an A6 2004 2.5 TDI V6.

Thanks in advance for any advice or ideas 

Andrew

Thinking it could be the oil cooler 🤔
