X3 06 taking little longer to start.

Hello Everyone,

Hope everyone had good holiday
My X3 is taking little longer to start. It not battery problem and its not stater problem because there are no signs of that.
Does that meen I need tuneup? You think it could be because it time for new spark plugs?
It has 60k mils.

Thank you in advance.
Yaz.

Next time you start it turn it to "on" and give it about 10 seconds before you turn to "start". This allows time for the fuel pressure to build up before you try to start it.

If that improves it then it's likely just the check valve in the fuel pump allowing the fuel system to depressurize itself overnight. It's really no big deal if that is what it is. Just pause between on and start. Sometimes it will clear itself of whatever is causing the leak and go back to normal.

X2. I just made it a habit to wait until the third "beep"

Also, does it feel slower to crank? like the starter motor turning slower than usual? it could also be the battery letting you know it's on its way out...

I tend to do the same on my X3.

I started to do it on my e46 as well but only after leaving it for a couple days without a start.

I wouldn't think the plugs are the culprit.

You might want to run a bottle or two (one at a time) of Techron through it and see if that helps.

Same here

Ours always has requred more cranking than I felt should have been required. I recently read a thread here regarding waiting a couple seconds after turning the key to position 2. I usually wait until the dash lights start turning off (maybe 3 seconds) and it works for me. Can't tell you why though especially in your case where it was cranking immediately apparently and then all of a sudden it wasn't. Techron, different gas nor a new starter (obtained under warranty) had any impact for me.
