Thank you so much, Terry.

I have parking spots but no garage spacious or lit enough to work in. Well, one spot is, but the queen boxster lives there .

Since I'm not doing plugs (they are only 10k old), I thought I could do the coils on the street or in my driveway. Is that too optimistic (or ghetto)? Everyone made it sound so easy.

It should be easy - just take the plastic cover off to access the coil packs. I tend to not want to do things on the street because that just temps fate with some silly little thing you need and don't have, and of course the car is apart.

Here are the instructions (for an E46, but the only difference is how much of the cabin microfilter housing you need to remove to get to the rear part of the engine cover): https://www.glaver.org/transient/coils.pdf

Give me or Sue a call here if yu run into anything - we can at least roll w/ instructions, tools, and parts.

This exact scenario played out a few months ago when I swapping the steering wheel of the 535i. I broke a small wire connection and the car was on the street right in front of my living room. The car without a steering wheel sat there for about a day. Our town has no street cleaning though. Which means there is the occasional carcass () or eccentric car that never moves.

It should be a 20 min job roadside or in a parking spot without issue. The only tool needed is a socket to remove the engine cover. The coil latches swing open (be sure you swing them all the way vertical) and disconnect. There is a hole in the latch to put your finger through and pull them out. The plastic at the hole is a little sharp, so you may want some light gloves or a rag to displace the load a bit. pop the new ones in (be sure the rubber sleeve doesn't bunch at the top of the opening, snap the latch down and you're done. (at least that was how it was on the n54).

Did the DIY. I had some other stuff going on, so it took the better part of a day on and off. Total time spent, way more than an hour, probably two. Next time around, maybe 30-40 minutes, done carefully, but definitely not roadside work. Some cables/harnesses to unclip and move around. Turbo intakes all running on top etc. Coils themselves were relatively easy to pop in and out. Access? Not so much. I think part of the problem was that there was exactly zero write-ups/DIY's to follow for the f10 platform. Only for e90 and f30 with the same engine. So I had to remove as I went and figure it out.

Anyway, it does feel a bit better, still a slight idle shake but dare I say it, car feels smoother and stronger 2 to 4k rpm, i.e. under load. We will see if the CEL comes back.
