Mine does basically the same thing as yours but not quite up to 120.
Yesterday the car was at normal operating temp for open road driving of being just past the 95C mark, so probably around 100C. There was a crash on the motorway and it took about 20 minutes to drive 4-5km with the speed never going above 20kmh. In that time the oil temp got up to being aimed at the 1 in the 120, so probably 110-115C. I don't think I've ever seen it that high before but as the engine doesn't have an external oil cooler it is fairly typical to see this sort of behavior in traffic. The outside temperature was 23C.
I don't know if there is a way to check the flow through the heat exchanger, but here is the link on Realoem.

By the way, yes the search result is for a 530i. The N52 engined cars were designated 530i by BMW but for some reason the Japanese market cars were badged as 528i. The N52B25 cars were 523i and the N47 diesels that were 520d everywhere else were called 523d. |
Yeah, I got little confused with badging coz car said 528i on trunk and when i tried to decode vin, some websites say that it's 530 and some say it's 528
Thanks for reply and sharing the link.
I'm planning to observe little more and then if all stays same I'm probably going to check Thermostat & water pump.
No leaks visible from coolant hoses but will double-check that as well.
