Default Ignition delay on Key Contact

Hello guys,

This is probably totally normal, but I wanted to ask (I've had my M3 for only 2 weeks, which is why I'm asking so many surface-level questions):

Probably 1/3 of the time when I turn the key forward to fire the mighty S54, there is a small delay before anything happens. Now, she always roars to life within 1 or 2 revolutions - that's not the issue. It seems to be an electrical issue (problematically or hopefully intentionally) that causes this slight delay.

It's never failed to start, but even after a year of driving an 05 330, it's a long enough delay for my heart to skip a beat and think, "Oh crap! Starter?! Battery!? What!?!". Since I'm a hyper-active, turbulant madman, this might be a 1/4 or 1/3 second delay.

Is this normal, as the computer verifies the key? Or is this a sign of an issue that I need to investigate?

Thanks!

Okay, so it's not normal... Roger that. She's going in the shop tomorrow at 8am for two days - Carbon Fiber intake! Headers! Section 1! Section 3! 50k mile maintenance/service! - so I'll add that to the massive list.

She's a 6 speed manual, but I've made sure it isn't a matter of not having the clutch depressed far enough.

Thank you guys.

I'd be interested to hear what you find out, I'm new to mine as well and just figured that was normal. Always starts but usually have to hold the key for a moment before it does anything. Mines an SMG, not sure if there would be any difference.

I highly doubt this is an issue to worry about. Mine did this on its original starter. I replaced my starter last year after it finally died and the car still does this every once in a while. My car is a 2004...so 11 yrs on the original starter. Nothing to worry about if you ask me.

Mine is an '06 with 64,000 mls, manual and it does it everytime, there is a fraction of a second delay b4 the starter turns but it starts everytime. I woudn't worry about it.

Okay, thank you guys! That's one less thing. I had a 2004 Land Rover Discovery whose starter/solenoid needed a good ass-beating every now and then.
