VW passat 1.8T oil leaks?
I've noticed some coolant mixing with oil next to the oil filter. It's also mixing where the oil filter is connected. There's a sensor right above the mixture but I'm not too sure if that's the problem. What is it that I have to replace?
You don't have a "oil cooler" it is more a oil stabilizer as it uses engine coolant to keep the oil at the temp of the antifreeze.
These are know to leak and intermix oil and antifreeze.
You need to buy a replacement
