545i manual - momentary power loss
I've been scouring the net for weeks and can't figure this out. I have a 545i manual and pretty much every time I drive it, without fail, after about 1-2 minutes, as I'm accelerating, the car will momentarily lose power (like half a second). it only does it once and only within the first couple minutes of driving. I can't for the life of me figure it out. Anyone else experienced this or have any ideas?

Mine sort of has that feeling but barely almost unnoticeable, I feel it about as I leave the drive way and about 1 block from the house almost at the same spot every time. Almost like a hiccup.

Loss of power or hesitation would describe it. This is a MT so that doesn't answer the problem here. It really is like a hiccup though but super fast. Almost like a miss-fire but I have no codes or errors.

I had the same problem a few weeks ago. mine started same way momentary power loss when accelerating from lower gears. there was no codes at the beginning but then I got misfire and SES light. replaced all ignition coils and no problem since. everything is normal. one of your ignition coil is going bad. you can replace all of them or wait till codes come on to find out which coil is dad and replace that particular one or get the meter and check them individually.
check my thread also that I have started a few weeks ago
