How to Replace Ignition Coils 2007-12 BMW X3

I want to disconnect the battery. So, get to the battery in the back. Just use a 10-millimeter socket, remove the negative cable, loosen it up, just slide it off and out of the way. Make sure it doesn't arc out on there. Take these two trim clips out. Just use a trim tool. Try to take the center part out first, and take the push pin out. Do the same on that side. I'm gonna take these two bolts out on this side and the two on the other side as well. On this side, I'll just use a wrench and 13-millimeter and the other side, I can use a socket and a ratchet. And slide this bar out of the way. You want to take this cover off. Twist this right here. This one over here as well. And one on that side. And just grab it, slide it up and just pull the cabin filter up. I'm just going to use a bungee cord. Just go around the wiper arm, just to hold this up.

I'm gonna just keep that out of the way. I'm going to take these four bolts out. Gonna use a T30 socket. And just grab this piece. You should be able to slide it up. Slide this out, and throw all those leaves out. Now, I'm gonna use a 5-millimeter hex bit and take these four bolts out. There's two in the front, two in the back. And just slide this cover off. Just like that. To remove the coil, disconnect the connector. I'm just gonna slide this tab up just like that. And then the connector's going to slide out. It's going to slide straight down. You can grab the coil, just rotate it a little bit back and forth. Try to slide it out as you pull. Now, we're going to pull out the rest of the coils the same way. Now, we can put the coils back in. And reconnect them. Get the connector lined up and push down and lock. Do the same for the others. All right. Now, we can align these wires up. Put this through this retainer there. All right. Slide the wire through here. Put the bolt through. We'll tighten that down. And snug that up. That's good. And slide this thicker wire on top. And slide that right there. Put the nut on. And snug this up. That's good. Put the cover back there and line the cover up right here and lock it in place.

All right. Take the cover, line the cover up. And take the bolts, get all the bolts started and just snug these up. Not too tight. Take this panel, get this lined up. All right. Get that to line up. Get these bolts started. And just snug these down. Now, I'll take the bungee cord away. Put the cabin filter back in. Slide that in position. Actually it goes this way. That looks good. Put the cover on, tighten these down. Turn the locks. And take this bar, line this up. Put these bolts in, two on this side, two on the other side. On this side, I'll just use a ratchet wrench. Tighten these down, snug them up. And take these pushpins, line this up, and lock it down. There we go. Now, we're gonna reconnect the negative battery cable. And tighten up the nut. Just make sure you wiggle it, make sure it's tight. That's good.
