Audi S3 8P Won’t Stay at 90 (oil temp) HELP

[Az97iah05]

Hi all,

I have recently got an Audi S3 8P 2007. First thing I noticed is that when idling it reaches 90degrees both gauge and digital reading. When driving it drops to 70-80 on the gauge and reads 77-84 on the digital dash.

First thoughts - thermostat! Had this changed and the issue still persisted. Had it changed again to be sure, tested the thermostat it works. But no the same issue is occurring.

I let the car get hot idling then took it out and it seemed ok. Cooled a tad (65) then went back out and can’t get it above 80.

I am stuck.

Any ideas?

Thanks guys!

Apologies I worded that badly. I let the car cool to 65 and then went back out for a drive.

Yes still does it with No AC or heating on.

I believe it is holding pressure, best way to be 100%?
