I need help with my R56 MCS, some time ago I realised that my fan is not working so here is image with my coolant temperature before some tweaking:

so it goes to 105 and stays there but after resistance mod and some playing with climate control(low temperature and maximum power in auto mode) my fan started to work at 2nd stage i guess and it started to looks like this:


Also I had some issues with low oil pressure light after some driving, this probably is tied together but I have no idea where is my problem, I hope someone knows whats this is about.
