Hi, i bought innovate mtx-d ang scg1 3 months ago. 2 days ago suddenly,at cold start, my oil pressure increases slowly, at past it sticks at 6.9bar at first cold start. On the other hand my values of pressure dropped at warm oil temp %40. I changed the oil but did not make any difference. I want to know are these symptoms refer to broken pressure sender or am i should look somewhere else ,here is the cold start video. My oil temp gauge not work, please neglegt it. and the values are metric(bar)
