Oil temp issue?

[Arvai]

So my 99.5 B5 1.8T is having issues keeping the oil temps down while going down the freeway. I’ve seen the temps get near 220 while cruising for a while doing 75. It’s ok in the city but not at higher speeds. I went ahead and checked the oil cooler and even replaced it to play it safe, and it made a barely noticeable difference. I’m wondering what could be causing this? The oil is perfect on the dipstick, and has fresh coolant. Car doesn’t run hot coolant wise either. Im at a loss. Any help is appreciated!

thermostat, radiator, fan, oil temp sensor maybe. Could be a bad connection with the sensor

Make sure you do not have a small oil leak. The hot oil dripping from the oil cooler side can reach the pan sensor. FYI.

A little late to be of help.Consider that this is the normal, ie the design . My MY15 S3 8V runs at this temperature when fully warmed up and I am content with that. To evaporate dissolved water in the oil the temp needs to spend time at 212 degrees
