Hey guys so my car has been taking ages to warm up. From cold start i would drive 10-15minutes and it would only reach 2 bars, after 15minutes it sometimes goes to 3bars but fluctuates back down to 2 bars again and back up. Some days after 30minutes of driving it will only stay at 2 bars. any ideas?

 

your thermostat may be stuck open? at least that's be where i'd check first.

 

^ I agree,thermostat.
