Hi, In the mornings I have to start my car 5-10min prior to leaving my house to heat the car up, otherwise the yellow engine light comes on (if its cold). The light stays on until I start up the car after 3x then it comes off. Do I need winter fluids or should I do an engine flush? Under -30 weather the car is very hard to start aswell..

I also have 2 sensors out in my car. The E-brake sensor (ebrake is working just fine) and the passenger air bag sensor. Are those a must fix? And how can I fix them?
