I got a 2004 BMW X5 that gets a trans fail safe light that only comes on after the car sits overnight, I can run the car for 5 minutes then shut it off and it goes away until it sits for 8 hours

Asked by John Nov 04, 2017 at 10:15 PM about the 2004 BMW X5 4.4i AWD

Question type: Maintenance & Repair

Ive replaced the battery but it still doing it, like I said
after running the car for 5 minutes I can shut it off
and the alarm goes away and won’t come back on
the rest of the day, until the car sits overnight, I’m
not sure if the car is overcharging when it starts and
it gives me the alarm or something else, I’m not
having issues with my transmission it shifts fine
other then locking me out of 1 and 2 gear when the
alarm comes on. But it will reset after I shut the car
off and start it back up.

You probably need to take it to an authorized BMW repair center. You need a code identification computer. It sounds like one of two items either a bad temperture sensor or problem with something in the cold start circuit. The problem I keep having with my one engine is the air injector in the cold air circuit keeps getting cloged and needs to be cleaned with a pipe cleaner, but it keeps kicking back a code for cylinders 5 and 6 in the cold start mode.

Then i jump start again and drove for another 4 mils to a parts store. They checked the battery and said it is fine, but the machine says 9.8 - 10 low but good, then we try to start it but it was in starting, so he jump start it agin and i drove about 15 miles, then i shut off, and restart few time, without any problem, but after a little while the alarm go of by itself.
