F48 cold idle

Eggbert · 10-24-2020, 07:20 PM

Anyone have cold idle issue on F48 where car kills on startup? Doesn't throw a code for BMW but my Carly picks it up. Seeking solution.

How many kms/miles on the odo? Have the spark plugs been changed? If not, and there's >40,000km/24,000m, that's where I'd start.

Dealer implemented a coding fix for me that worked.

I’ve read like above that coding fixes it. My dealer couldn’t get it to do it of course and said if there are no errors they can’t really do anything. Car has 61,000 miles. Pretty sure original plugs. It’s done it in cooler weather since I’ve had the car.

If it were mine, I'd "invest" in an hour of diagnostic testing on the computer at a trusted indy or even at a dealership if nothing else is available close by. Obviously Carly is picking up an error, although you didn't mentioned what the code was.
