E90/E91/E92/E93 (2006 - 2013)
I have a 09 328xi coupe with the oil temp gague. The other day it started fluctuating while i was driving at operating tempature 10-15 deg (f). The dealer is claiming that its normal but I have never heard of a car doing this nor have any of mine (97 dodge, 03 Mitsubishi, 97 328i, 11 328i)...
