135i starting in -25c weather oddly?

Curser55 · 01-03-2022, 05:37 PM

Sorry I had no clue how to word the title but basically it’s really damn cold here in Alberta, Canada right now (-25c) and my car has a little trouble starting as expected but pretty good for a car with no block heater but when it starts up it idles like the car is already warm? No high cold start idle just instantly at regular idling rpm’s? Seems really odd and only ever does this when it’s super cold out. Is this something I should be worried about or is it normal?

Do you have a tune on the car ? MHD has a quiet start option that drops the revs immediately. The high idle on startup is actually to heat up the cats quickly.
