Does the n52 have a habit of blowing coil packs?
There are a lot of posts on here about coil packs but could not really find anything regarding any issues with wearing out coil packs too quickly.
I replaced mine Summer of 2017, and just last night she, 2013 128i, started doing that little engine rumble when they start to go. My curiosity has anyone had any issues with coil packs going out to fast? I am sure there is the possibility of it being a bad part also. To boot, I do have a Stage 1 tune..I don't push the engine very often; maybe in DS mode about once a month for less than a few miles on the interstate. It is my daily, most of the miles are commuting and drive in D mode. Looking forward to everyone's responses. |

I think the coil pack issues are compounded by spark plug issues, as the DME will charge the coils more aggressively to compensate for worn plugs, wearing the coils even faster. I don't know what really causes either of these issues, but my car, with 181k miles on it, hasn't had any issues since I bought it at 159k.

I'm wondering if the tune overworked the plugs, which is likely what you were suggesting in your original response. I've read in some posts that tunes can wear those out...maybe swapping out the plugs and singling out the coil should fix it right up |

You might be driving your car too gingerly, these engines like to be pushed a little. I actually have to beat on my car, just a little, every day to actually have a smooth, and enjoyable driving experience.

Yes throttle adaptations that can be reset and AT adaptations if you have an auto.

If it were me, I would replace the plugs any time I had the motor torn down to the point that the only additional labor was screwing out the old ones and replacing them. Same logic as replacing the clutch any time you have the transmission off. Regardless, as usual I consider the practical service life half of what BMW says, so I do the plugs every 50k miles.

Most modern plugs come pre-gapped, but it never hurts to check - I've found them out-of-spec out of the box. Of course if you're dealing with multi-pronged plugs they are non-adjustable.

I did plugs a couple of weeks ago and checked the gap. They were not consistent. Not by much maybe 0.002 to .003.
BTW - my plugs were really hard to loosen. I think they were slightly seized up. I put an ever so slight smear of copper based anti-seize on the new ones and reduced the torque spec by about 25%. Opinions are all over the place on using anti-seize.

I always slather anti-seize on anything that might stick in place inconveniently. As long as you adjust the torque (wet vs. dry torque is a real thing) it shouldn't be any issue. I've seen some very difficult to image damage caused by anti-seize on lug bolts being rattled on by a tire shop gorilla with a giant impact gun and not an ounce of common sense.
